I never had audyssey, but I have been very happy with the 2x4 balanced. Very slight increase in noise can only tell when your ear is right in the horn. Not even worth measuring.

good luck on the mini, I like mine. On the sunfire I do get a little noise but cannot detect with my ears past 3-4ft even in the room is dead silent. I might sell my sunfire too but maybe go the other way and get more power. I need to read more specs and get a better understanding but I think the LG FP10k has a much greater dynamic range including lower noise floor at certain gain settings than my sunfire. I need to verify and understand that better before purchase though. I agree getting a lower noise floor in the room is so important especially for movies. For me the projector is the culprit right now!!

Speaking of Imax, I was thinking that my Noesis couples with a couple of HSUs were sounding close to the Imax, until I decided to watch Gravity tonight on my local Imax... I was yet again astounded by the sound quality of it... damn.. it still puts my Noesis/HSUs to shame... it's like taking it up several notches... Looks like our brain forgets after a while and needed to be reminded again... I wonder how many subs I'll need to add to the mix to get the sound level to Imax???

Of course, we'll have to revisit this after I add my Orbit Shifter to the mix... The highs on the Noesis are as clear as the Imax, but currently the mid-bass is what's missing most (Imax only goes down to 22 hz anyways but it's HUGE down to that range).
Indeed... I found interesting that he actually said that for movies you don't really need more than 20hz, and I tend to agree. My local Imax has BY FAR the best sound system I have ever heard, ever... and it only goes down to 22hz...
cool, I am pretty confident once you get you OS dialed in with you other subs you will challenge the IMAX at least as much as you can in a small room. Will you have independent control over each subs delay, and crossover slopes?

Mine doesn't pass on any noise whatsoever. But after proper cable management my Emo didn't have an audible problem at the LP. The emo did have a little more hiss than any of the others I have tried, but the sunfire and the 7-350 have been perfect. I can get a little bit from the surrounds when I walk directly underneath them, but once again, that is when my head is within a foot of the speaker. I know my speakers aren't JTR, but they ARE 100dB's efficient so the same thing would result there...
post #11226 of 18481
Mine have a very distinct buzz from the amp, not a hiss noise and it only comes from the CD.

I've disconnected the amp from everything and only had the speakers hooked up to the amp and it still has a very slight buzz.
Had two of my buddies over that are really good electricians to make sure I didn't have any ground loop issues and it still hasn't gone away.

I'm thinking I'll contact Emotiva about the buzzing next.

Every AVS guy I've had over wants the main seat, but friends and family - not so much.

Yes, and even forgot his beer..........for a short while biggrin.gif
post #11228 of 18481
If you have REW or another program with RTA capability put the mic up to the CD and get a snapshot of the buzzing.

I would bet you will see peaks at 60, 120...which is indicative of a ground loop or other grounding issue somewhere.

If not, I would send the amp back.

I would agree. Another test is use a cheap $2 cheater plug and see if the noise goes away. If it does, it is a ground loop. I had one last year and use the cheater plug to identify the issue. I can say with my external amp my front 3 speakers are 100% noise free. There is a tiny buzz on one of my surround channels but you can't hear it unless you are 2 inches away so it is not audible by me at all in regular viewing conditions.
post #11230 of 18481
Yep, I reconfirmed my no-buzz policy last night after I posted and I could literally sit in the MLP, with the HVAC completely off, the minifridge and laptop in the basement off, and as complete silence as I would ever get in my theater and it was almost creepy quiet. with the lights off it was even disorienting....

I'll have to try the REW method to see if its ground loop issue because I don't think I've ever seen a 20amp cheater plug and this amp has a 20amp plug on it.

Hey everyone, it's me again....(hey, I see eyes rolling already)

Ok so I left some pink, white and brown noise loops running the other day all day and the speakers definitely sound a little fuller. To the point where I forgot to turn the sub on and I heard more midrange that I was looking for when I was playing the speakers.

All that being said, now Im getting frustrated with placement. These speakers are very finicky in their toe. I almost feel like the dispersion is so controlled that you really do need to sit in the sweet spot to hear things correctly. This is something I hated about my friends Martin Logans and why I didnt go for them ever. When I ran the Audyssey for my listening position on the left side of the couch, everything sounded good until you moved over to the other spots on the couch. I then ran Audyssey to set the center of the couch as main and the other two seats as second and third positions.

I was watching the third episode of "The Blacklist" last night on demand. I had chosen the HD version but apparently it still came out stereo. The whole time I was messing with the toe and placement of the speakers. When I was sitting in the left side of the couch, I kept hearing separate sound from both speakers. There was no feeling of centered sound unless I sat in the center of the couch. This was infuriating. I kept twisting the speakers until they were each facing past any seating positions on the couch(crossing each other in the center of the room in front of me). This worked better but still wasnt able to get the best centered sound unless I was in the center of the couch. If I closed my eyes, I could still place the speakers in the room. Again, obviously when Im listening to a movie and the center channel is on, this scenario completely disappears. It was this situation that brought this annoying to my attention though. Then I started listening to music again and realized it was happening then too.

The sound is great, dont get me wrong, its absolutely fantastic. I am just at my wits end trying to get these set up properly. Im more of a set it and enjoy it kind of guy. I dont have the time or patience like I used to to fiddle with everything to get it sounding right. Am I the only one with these problems? If so, then it must be me and not the speakers.

I hope so. I bought a processor from Johnson who also sells the clones. let's see if that works well for fine tuning my eventual multiple subs...

Jbrown just got a 20a cheater plug from somewhere, don't know where but hopefully he will post where he got it.

No eyes rolling here. This is the most helpful group of folks I know of in the speaker section. Good people all around. My major question to you though is, do you have any room treatments? HE pro style speakers yes, are very sensitive to toe-in and moreso than consumer type speakers as they are so directive. Once you get them right though, the staging should be better than any other speaker. Don't assume that each need the exact same toe as the other as well.
post #11235 of 18481
Yes, I have treatments on my back wall and ceiling as well as bass traps in all four corners. Thick wall to wall carpeting as well. Suede couch, not leather. And most of the time watching with me is my fat friend who also seems to absorb sound.

Try moving your "fat friend" around like a customizable room treatment and find his best spot for optimal sound..then tell him never to move again :-)

This had people in the office wondering what I was laughing at....

Any side wall treatments? Seems like you have a good amount already, but side walls matter too smile.gif Perhaps have a pic you snap and post of the space?

post #11240 of 18481
placement is one thing ive never had an issue with. ive done multiple REW runs and its pretty much identical anywhere on my sofa. I also dont know how good your on demand sound is but for me, its the worst of the worst. it never sounds good on any setting with Shaw.

How far apart are the L&R? The wider they are the more area you can cover and the further away the LP is the better.

You may try adding another Fat friend for more even absorption. biggrin.gif

I am going to take a shot here.. I have a feeling you have 'over treated'. I have listened to speakers in dozens of showrooms here in my country, none of them sound even as close to my 'untreated' room with my 'natural bookshelves all around'.

It's a shot in the dark though. Try taking your system to another 'untreated' room and see if you still have those problems....

I know this is an unconventional take on the matter, but sometimes, when everything else is eliminated, the only thing we did not think about might be the culprit.

I am going to 'assume' the 228s are excellent speakers considering the 212s I have are so darn good, so there must be something wrong in the setup...

I am currently living in a rented house. I got permission to 'take out the windows' and build bookshelves all around the room... at least on 3 walls (one with a computer table at the bottom end, then books up top). As you can see in my speakers pic, you'll see the tv surrounded by books...

I like living around books... this is not my 'dedicated ht' or 'listening room'.. it's just my bedroom..

I am currently renovating a house i bought 3 years back (basically tearing down the entire house and re-building).. it'll have a basement and that's where i'll be putting my actual HT... It's coming along, albeit slowly...

Dammit CoolGeek...this sounds like an excuse. I want to hear about the OS knocking books off the shelves already. smile.gif

I plugged my 7350 into a 20amp socket and had no humm through my two Definitive technology Pro Monitor 1000's. 91 db sensitivity only though. I will try them tonight with the black Furman adapter from Amazon I got though. But if you own you can just replace the 15 amp plug for a 20 amp plug.
