Hey Matt. Thanks for checking in. I have been working in the background on a few things and here are the high-level updates:
  • Bought a third Sherbourn PA7-350 so ALL of my amplification will be matched for all speakers and balancing subs, excluding LFE
  • I transitioned from a UH480 and ATH1 automated sled to a DC1 with ATH2 automated sled
  • I purchased two Stereo Integrity HS24 24" subwoofer drivers to augment my LFE beyond the four UXL-18s I have going into the room
  • I bought a few more Savant SSR-1000 remotes to complete the automation system control for all the rooms I wanted the handheld remote (total of 7 rooms, including the theater)
  • I've dumped the idea of using Quest panels for the room and will be pursuing a 4" DIY panel similar to RPG BAD Panels to get the lower octaves of diffusion and absorption
  • The room rendering is complete and only lighting has to be added over the next couples of weeks, along with some subtle tweaks. Looking forward to everyone's feedback on the design aesthetic, for sure!!
  • After talking with a number of preamp / processor manufacturers, it is apparent that it will be best to wait on any SSP purchase for at least 6-7 months. Only then will full-spec HDMI 2.0 boards with HDCP 2.2 be available and integrated into the new hardware. If I bought now, there would be upgrade cost(s) later and I want to avoid that.
  • I keep coming back to the same projector as you - the Sony 600ES - because of the native 4K, sufficient brightness and HDCP 2.2 compliance on HDMI 2. If that Sim2 was 4K, I'd snap it up immediately. I just can't put that kind of cash into anything 1080p at this point
  • I've nixed the idea of going with an HTPC. I will use my Synology NAS as the DLNA server for any streaming content, so no additional hardware costs and no further installation considerations.
  • I will be waiting for Oppo to release their 4K Blu ray player sometime late next year and will not be purchasing any interim machine. If I need Bluray playback in a pinch, I'll use my PS4.

That's it for now. Final rough inspection for the rest of the basement is scheduled for Monday. With any luck, drywall will start by the end of next week.

My deal-killer with the 600ES is the 120ms of lag, making it unusable for gaming.

Tim - for what it's worth Jeff Meier isn't a fan of the 600ES. Can't exactly remember all the reasons but had to do primarily with the lens quality.

Hey, Tim.

Nice meeting you last night.

Tim comes to my place, brings Pizza, Skyfall as a gift, and the fantastic Dolby Atmos Test disc for trial in my theater.

Tim's meet is one I'm traveling to after getting the skinny on his plans...when it happens! Should be a reference build in all respects.

Fun time demoing last night and shooting pool.

Thanks!

I'd be interested what he prefers. To me it is the best value out of all the high end projectors I've seen. Let's see...main pros: tons of light output (albeit it on noisy high lamp mode), very decent black levels, superb color performance (accurate saturation and luminance tracking), motorized zoom and focus so you don't have to use an A-Lens. Value seems an odd word to use for a $15k projector but the image is fantastic. I think you'd have to spend $25k plus to get anything better. I don't see any better options on the market at the 600ES price point and there abouts for most AVSers.

Actually Tim, my My SIM2 Lumis/HOST that we watched was calibrated by Jeff Meier just a few months ago.

The picture as you saw was rich and dynamic.

The only thing you might keep in mind is that a HTPC is much more than just storage and streaming. It is very handy for Room measurements, DSP configuration, Web content streaming, etc, etc.

Also I dont think MKV rips will stream DLNA. Does the Oppo support MKV? Will the NAS/Oppo work in this way? IDK, and you might not be interested in MKVs, so thats up to you.

Honestly I cannot imagine my house without a HTPC now that I have one, it does so much. I built a modest one and I can serve several HD streams all over the house simultaneously while the main system in the LR is being used for whatever, streaming(net) watching movie etc.

For standalone disc playback, I still like something like the Oppo. The HTPC has a rabbit hole of configuration and setup steps. The Oppo, you pull out the box, plug it in and it works.

Thanks! I see the light at the end of the tunnel for all other projects being wrapped up with only the theater remaining. I have some West Coast travel coming up in January and February, so perhaps we can finally get together for a little project inspiration.

Don't worry, Jim, you'll get there eventually. After all, I know you were waiting for the dust to clear on 3D audio codecs before moving forward with your plans, right? Take some comfort in the fact that my theater has been in studs for just over two years with only electrical and low voltage added to this point.

I've owned a PS4 since the 2nd week they launched and have yet to buy one game. I'm not sure which games are unusable with the projector latency, but I would be most inclined to purchase a driving/racing game when the PS4 eventually relocates to the theater, so I wouldn't expect any problems.

It's probably the acrylic optics vs. the glass optics of the the 1100ES, but I have few alternatives with adequate brightness in a native 4K projector that doesn't bust the budget. If there was a 4k version of the Epson 6030, I'd go that route. The price of the Epson LS10000 is such that I am in the 600ES pricing territory in either used or online e-tailers. That was my thought, at least.

The word of the day was 'DISAPPROVED'. The inspector had previously pointed out a few things I needed to fix (add receptacles since a few small wing walls "broke the plane of the wall", requiring more outlets as per the NEC), which I did, but now there were problems with my fireblocking, almost all of which was focused around the pool table area where I added the perimeter soffit and coffered ceiling. This then 'joined' the ceiling structure to the wall structure which is a potential route for fire. So I'll be adding that this weekend and having another inspection on Monday. My drywaller cancelled anyhow, so no worries there.

Jeff - I am so glad that our schedules allowed to get together. It was well worth the trip and thank you again for your hospitality.

It goes without saying that you have an incredible system that is equally adept at being open and airy while bringing BRUTAL LFE with all of those Seaton Submersives!!! The Datasat RS20i, the Sim2 Lumis, the Quested speakers and amps....the system was truly outstanding. And I had just as much fun trying - trying - to hold my own against you in pool. I clearly need to practice and get the rust out of my game after a thorough pounding into the felt!

I look forward to getting together again and having you down for the unveiling of the Stonewater Cinema, whenever that is!

These were my thoughts exactly. My hope is Sony will release an update to the 600ES by the time I need my projector next year and have taken market feedback regarding latency, the lens system and additional brightness to heart. Or perhaps Epson, JVC or others will jump into the game at the same or lower pricepoint for affordable native 4K projection.

Hey Nick. Thanks for checking in and sorry to have missed you at the GTG last month. I was unfortunately marooned on the West Coast over the weekend for work. We'll have that beer together eventually.

My Synology NAS has DLNA streaming capabilities, so there's no worry from that perspective, it just lacks the fancier GUI of JRiver, XBMC and other programs. I will probably have some sort of HTPC, but I can foresee very limited use in my system as I don't plan to rip content. I sold off my entire DVD collection and never made the investment in many Blurays since I didn't have my system up and running. Now that 4K Bluray is on the horizon, I am definitely suspending any media purchases until 4K Bluray is launched. Of course this would be a revolution in hardware for an HTPC to function in the same way it does today for standard HD Bluray content, so it's something I'm going to hold off on for a good, long while. I just don't have any content to rip to an HTPC and the content I would buy is going to be 4K spinning disc.

Thanks for the complements. We'll do it again at your place. Your place will likely be the ultimate when it is completed.

Looking forward to it (and more pool).

Have you tested any of your 7-350's to see if they have the dreaded hum?

Ya! That's what it is! Nothing to do with not getting off my....chair. I finally picked up some empty wine boxes today to pack up some of the wine from the temporary racks so that I can get them out of the way! Maybe tomorrow (next week) I'll get to installing some of the racking...

Sorry to hear that you were disapproved. I know the fire stops could be awkward to fit in around the soffits. As a compromise would the inspector consider filling, say 2' of the stud space at the soffit level with Roxul insulation . Even the regular thermal batts are flame retardant. They demonstrate it by holding a butane torch to it.

Season's Greetings and happy New Years!

Not one of them. The two I bought directly from Emotiva are still in their sealed boxes. For the third, I was the purchaser of Dave's Sherbourn amp that had a hum. I had it sent directly to Emotiva in Tennessee to be fixed under warranty en route to me. After a day of bench testing by their QC, they weren't able to recreate the issue, hear any hum and concluded that it met specifications.

I was intimately involved in the high voltage electrical layout and design for the Savoy theater and David told me that Jeff Meier said the amount of electrical noise was extremely low and among the best he had ever seen. Given the accolades for the electrical layout and the fact the amp still had an unresolved hum, it will be on my 'watch list' when I go to install. I'll probably hook up a guerrilla system first to see if there is any hum before permanently installing.

I wasn't too worried about it but the stink of it was that the same inspector had been out before and didn't even mention it, so it was something new he found. They said it could be any kind of blocking - scrap studding, OSB, Drywall......practically anything I had on-hand.

Merry Christmas to you and yours as well!

Do you remember who you were working with from Emotiva?

I worked directly with Lonnie Vaughn for a week over the phone. (he's the VP of Emotiva)

I tried everything he requested despite having performed these things already in the past. Mine is a buzz, not a hum. Could be a harmonic of the line frequency but unknown at this point. To boil it down to its most simplistic form, I shut down every single breaker in the subpanel (100A panel strictly for the HT) except the 240V breaker for the 7-350. I disconnected all inputs from the 7-350. I disconnected all output connections. I took a bookshelf speaker and 12" of speaker wire and hooked it up to a few different channels of the 7-350 with a flash light (since I killed all other breakers for the room, including the lights). Turned on the amp and buzzzzzzzzz. This proves 100% unequivocally that the amp is producing the buzz with out any external interferer. I even switched the amp to 120V and ran an extension cord from another part of the home. No change.

Lonnie explained a story about a customer who had a nearby cell tower that caused issues with the amplifiers in his home. I explained to him the location of my HT (14' underground surrounded by concrete) and its design which would not allow that scenario to take place. Ironically enough, that is what I do for my day job.....supporting the engineers at the AT&T's, Verizons, Sprints....who operate Alcatel-Lucent base stations, switches, routers, SAM's, OMP's, RNC's.....so I was actually on my "A" game with that possibility.

Lonnie was going to have his shipping dept email me a return label so I could ship the amp back at no cost. I said I would do this AFTER the holidays. No sense in sending it back knowing it will just sit there since everyone will be in/out of the office due to the Christmas/New Years break. He agreed. I'll be packing it up the week after New Years. I honestly don't feel real confident it will get resolved having read so many different threads in this and other forums around the net. It seems people with the dreaded buzz send it back only to be told it can not be reproduced. If it cannot be reproduced they cannot fix it. He promised this "matter" will get resolved one way or the other. Not a hundy on what "other" is.

My take is that the power supply on the 7-350 is hyper sensitive. It's the only explanation why the amp would buzz at one location, but not another.

I was dealing with Michael Vaughn in Emotiva Technical support. Here is his exact message to me:

Thank you for sending in your PA 7-350 unit for repair; RMA number XXXXXX. I wanted to send you a quick email to let you know that we performed a full bench functionality test on your unit and we were unable to duplicate the issues you were experiencing. I had the amp tested fully on the AP and everything is running up to specs. We will send the AP report with the unit.

Your unit will be ready to be shipped in the next 1 to 2 business days. Please provide your current shipping address; if not already provided. You will receive tracking information from UPS once your package has been shipped out.

Thank you for your support,

I used the same high voltage layout / design that I normally use (similar to what I put together for the Savoy) and have a Richard Gray Powerhouse isolation transformer to handle power filtration / protection for all the equipment. Hopefully that will work. I haven't heard about all the horror stories, but then again I haven't looked. Fingers crossed, I guess.

You'll have to let me know how your situation resolves once the amp has returned from service. My amps will probably be installed late January / February time frame, so I will know for sure then.

By the way . . . . SWEEEEEET restomod on that Ford Mustang! Did you do all the work yourself? Are the three buxom babes related to you?

Like I said, based on the other stories around the net, I don't feel real good about it. To make it worse, Lonnie said the 7-350 is built like a tank. He admitted it is a "better" design than their own Emotiva Reference series amps (XPR). So now I'm seriously bummed about this. He said he worked with one of the bench techs to try and simulate my issue. He stated that the power supply in the 7-350 is a bit of a minor compromise in that it is calibrated for a line freq of 55Hz. This was a compromise between the US standard of 60hz and the EU standard of 50hz. They used a variable power supply going to the amp to alter the line freq the amp sees and used various speakers of different impedance's. Not once could they replicate the buzz :-(.

I'll let you know how it goes. Like you said, finger CROSSED.

Regarding the mustang....I haven't updated that page in several years. They actually changed the layout of the site a long while back and it really altered the way my pics were laid out and my text. If I had the time, I would go back in and shuffle things up to make it more readable/flowing. Oh well...life, right.

It sounds like you guys have all the bases covered on power supply...rms8 - turning off all the breakers except for the one feeding the amp is the perfect test...but then you said that you even "ran a power cord from another part of the house"...so I'm just going to throw this out there. If there is an issue with which phase you are on (which 120V feed you are on in the panel..."red" or "black") and interference between the two phases, then running a cord from another part of the house is a 50% chance of being on the same phase as the "problem". You would need to identify two outlets that are either on adjacent single breakers or open the panel to identify that the breakers are on opposite buzz bars (every 2nd single breaker is on the opposite phase), and then test with both outlets to make sure phase is not a the culprit.

I ran a temporary ganged outlet box with 14/3 split between the 4 outlets for a small HT setup. I got a terrible buzz from the powered subwoofer until I plugged it into the same phase as the amp. I now know that all the electronics in a system should be connected to the same phase for 120 equipment.

With the amp being 240V, could there be an issue with phase interference?

Again, not likely, but... I have a buzz in one of my LV pot light magnetic transformers. An electrician suggested that the plates in the transformer could be loose and vibrating...

I realize that given the quality of these components careful design should eliminate the possibility of these issues, but stranger things have happened.

rms8, if you have a subpanel for your HT, I remember having issues with a subpanel in my house, caused by a "bolt" in one of the panels needing to be removed that I think combined the grounds from the two sides.

PS sounds like we have some Mustang fans... when I was renovating part of my house there was an area of flooring that turned out to be old mahogany printing blocks with the etched plates still attached. One of them was for a magazine or newspaper ad "introducing the Ford Mustang".

I ran a cord from two different outlets. Each outlet was fed by a different breaker on opposite phases. I'm pretty thorough when it comes to troubleshooting electronics. I'll just add that I've been troubleshooting communications equipment (microwave, satcom, multiplexers, routers, switches...) since 1988.

The 7-350 is not the only 240 amp in my system. This is why I suggested the power supply in the 7-350 may be too sensitive.

That "bolt" was the bonding strap/bolt which is REQUIRED in a MAIN PANEL, but is NOT supposed to be in ANY SUBPANEL. The neutral and ground in a SUBPANEL are wired very differently vs. a main panel. In a MAIN panel, the neutral and ground busses are BONDED. In a subpanel they are electrically separated. The neutral buss is insulated from the panel by plastic standoffs in a subpanel and NOT connected in any way to the ground buss.
I disassembled the whole subpanel last month while trying to troubleshoot this issue. Removed the busses for the mains, neutral and ground. All has been covered in the panel.

The buzz is not a "huge" problem while a movie or music is playing since it is a constant level (does not increase with content). Unfortunately when any movie or music has a quiet passage, you can hear the buzz from the MLP. Disappointing to say the least from such a praised/hyped up amplifier. When you factor in the clearance price I got it for (950 shipped to my door), it just makes one want to cry since replacing it with something as powerful will cost incredibly MORE!!!!!

Progress Update

I have made a bit of progress in the theater by running all of the Canare 4S11 speaker wire necessary for two layers of 11 channels for the 'bed' layers and 8 ceiling speakers for 3D audio. For the LFE I wired for up to eight 18" subs plus the two 24" subs and up to four 10" balancing subs - all with heavyweight Belden 5000 10 gauge speaker wire. It's a massive (and expensive) amount of speaker wire.

I completed all of the high voltage wiring to the equipment racks which consisted of the following:
  • Three 20-amp dedicated circuits - One running the entire Philips Color Kinetics lighting system, one to run the Incandescent lighting system (Grafik Eye), one for all the theater receptacles
  • One 15 amp dedicated circuit for the structured wiring panel (including the entire security system) and looped out to the main equipment rack just because...
  • One Powerbridge from the motorized screen to the projector and back to the rack to be connected to the Powerhouse.
  • One double-pole 50 amp circuit using 10-3 for the Richard Gray Powerhouse
  • One 6-3 for a 60 amp double pole breaker for the latest version of the Richard Gray Powerhouse (if I ever upgrade)

Thanks for stopping by and subscribing! This project started small and has suffered tremendously from scope creep, also known as 'pre-emptive upgrade-itis'.

Now that the speaker and electrical is complete for the theater, things should get moving again in about two months. I will be wiring all the theater electronics when I install the Middle Atlantic racks since they sit outside the theater and will be up and running everything in the house. The theater will simply be a 'dead zone' on the system, although I have plans to rig up the speakers once the baffle wall is in so I'll have some tunes while working on the theater finish work.

You guys really have me on edge with these PA7-350s. I'm hoping I don't have any buzzing at all because that would be THREE high powered amps that I would have to replace which I definitely don't have the budget for. Maybe during the Christmas to New Year break I'll post up some photos of my high voltage electrical schematic along with some photos for feedback / critique. I'd love to hear your thoughts.

Just plug in the amp and try it. Use a power conditioner. You'll be fine.

The best I can do is have a good subpanel circuit schedule, plug all the amps into the isolation transformer and fire it up.

It is what it is at that point and if I get a hum on any of the three amps I will be reaching out to Emotiva to see what can be done.

Not yet. Trying to drum up a 'man date' since the wife has no interest in seeing the movie in the theater.
