Official Wyred 4 Sound Amp Thread - Page 17

I'm sure others will reply but my first suggestion is to ask EJ. Second, you can never have two much power. Third, if you ever switch to speakers that do present a tougher load with more you won't have to change (ie See point 2).

Can't comment on what you are mating them with but my experince with the MC channel has been outstanding. The "slam" is there, and then some as for mids I've found them to be clear, not forward and not rolled off just clear and non-fatiguing. The highs will depend on you. I've had some very open electronic amps matched with speakers that would either smooth them or add to the openness. In my younger years that was very interesting and very revealing but I found 2 isses with the extreme openness of other amps 1) Listening fatigue 2) challanges with finding good source material. So I now lean towards a more liquid top end that is revealing without the fatigue. The W4S does that for me and still is very open (ie not layed back) but others may be wanting for even more. I haven't had a chance to try my amp with more revealing speakers - I'm finishing up a room redo - but that type of a change may add to the openness without becoming to brittle. Will have to wait and see.

Forgive the indulgence, here's my beauty:

Hello Klao,

I'm sure that adding some line isolation and regulation would help sonics, but the amount of improvement is debatable. Different locations (homes) will have different power qualities, and some will gain more than others. The power supplies in the amps are really robust to start with; I don't think that they could run out of power unless the line voltage dropped dramatically.

The new STP has so much filtering that I would be surprised if it could be further improved from different line sources. With over 164,000uF of capacitance, the power supplies in the preamp are pretty much rock-solid. This must take partial credit for why it sounds so good.

Hello Liv,

Well, as much as I regret saying, I’ve been let down once again! I really hope that you didn’t have to go through this much trouble for your speakers. I’m unsure how AV123 finds enough people to continually put up with this type of treatment, and delays?

Please confirm that I’m not wasting my time, and that I should continue the wait. I find it really hard to "hang tight" any more, I think that ended a couple of months ago. I really need to get a set of full range speakers in my system to continue development with, and may need to start looking for other options…

Thank you,

Hello Chris,

That's great, thanks for the update. As much as I would love to stop other projects and start on that, we have our hands way to full at the moment. Every design we do is taken really seriously, and tends to take for what seems to be a long time. I think we may try to do such a thing after the release of the preamp, mini mc, integrated amps, and dacs.

So many things to do, but very little time to do them in gotta love it!

Thank you,

Hello Hogganbeck,

Thank you for your support. I'm sure that you would enjoy either one of those choices, but the ST-500 will offer more headroom. The only downside to the ST-250 is that even with efficient speakers, the level is somewhat limited. However, this is irrelevant if lower levels are desired, and you don't ever have a need for more.

As the OEM manufacture for the GCP's, I can honestly tell you that it's a great product! There shouldn't be any integration issues between it and our amps. If you're ever looking for more, I would highly suggest the gain cell mod. Doing so will greatly open up the preamp to another level.

Not that I'm favoring our own pre, it's just the truth. We used a modded GCP for a reference as far as sonics, and built the STP based on that. The comparison between the two is definitely not something that needs to be repeated over and over.

Our new STP is by far more open, spacious, and revealing. Much of this is due to the design. In all levels lower than unity gain, the STP remains passive with buffers to prevent impedance instabilities. Once unity gain is passed (meaning what goes in, comes out), the line stage is automatically connected and compensated for in our discrete volume control to allow for more gain.

The major advantage is that the unit operates in the passive mode for most levels. This offers drastically lower noise, and distortion. As a result, the imaging, and sound stage are precisely placed. Rick and I were talking after listening for a while with the level appropriate for conversation, and came to realize that the low level resolution was stunning! We've never heard a system sound that good at such a low level. The STP is really something to consider.

Thank you ILPS9200. I have to say myself, your stereo looks really good in that rack.

Thank you for posting,

Coming back to this

I think we've decided to use the trigger input on the STP to activate the HT bypass mode. Doing so will tell the unit to automatically go to a certain input (user defined) and set the gain to unity when a DC trigger is connected from a HT processor to the preamp. You can then connect the DC trigger outputs of the preamp to the inputs on the amplifiers. This will eliminate any other setting adjustments to be made, and should be very user friendly, even to the experienced.

What do you guys think?
Is there another use for a DC trigger input on a 2ch preamp that I'm missing?

No problem EJ, thanks for such a fine product,

EJ,

Any pricing on the preamp and any release date? What are your thoughts on the SQ differences between the Mini MCH and your current MC amps? I think an all black preamp and Mini MCH would look quite nice in my rack. I also like the way you are setting up the Trigger outputs/inputs, very user friendly.

Thanks, Bill

AV123 is another company like Emotiva, you get what you pay for junk. It is a crap shoot. Go to Salk Soundfor a speaker that will give value for years to come.

We are pricing the preamp at $1799, and hope to have the first units coming off the line late next week.

The Mini MC sounds really good, almost as good as our stereo and mono units, but not quite. As far as a comparison between the Larger MC and the Mini MC, this is one of those you need to reference back and forth for the differences which I haven't had time for just yet. That being the case, for HT, you would be hard pressed to hear any difference unless you were in the need for more power.

The LS line of speakers are in a whole different arena. I don't think quality or dependability is an issue for these. Salk speakers are awesome, but for the price, the LS6's or 9's are pretty hard to beat if you can ever get a hold of a set.

Thanks, EJ. I don't see any of the GCP mods referenced on the Cullen Circuits website--could you provide a summary of (or link to) the mods available and the cost for each?

Thanks.

Thanks. That looks like a mod to the GCPH phono preamp; I was actually looking for info on mods to the full-size GCP-200 preamp. Appreciate your help, though.

Hello Hogganbeck,

Yeah, it looks like we need to get a bunch of mods on the site still. The GCP mod is basically the same as the GCA/GCC mod with the exception of the output binding post upgrade.

The GCP has several options for mods:

Stage I: Gain cell mod only = $600
Stage II: Stage I + Input bd mods + 2 sets of WBT 0210-Cu-ms RCAs = $900
Stage III: Stage II + Power supply mod (adds triple-bypassed 176,000uF of capacitance, and a 25A shottky bridge rectifier. = $1200

We will try to get this up on the site soon. Sorry for the confusion.

Thank you,

EJ, I have a question......

On your website I am looking at the 5 channel amp, which 3x500 and 2x250

The header states

in the specs area it states...

May be a typo... is it supposed to be 500 x 3 (fronts) and 250 x 2 (rears) @ 8ohms
or is it 500 x 3 (fronts) and 125 x 2 (rears) @ 8ohms

http://www.wyred4sound.com/webapps/s..._groupid=18048

Sorry I'm a bit confused....
thanks for helping

Patrick

Hello Patrick,

Yes, I see there's a typo, you are certainly correct. It should say 250, and 550w. Thank you for the correction. We have updated the site, so it should be correct now.

Thank you,

I like your idea to use a trigger to set the bypass mode. Will using the trigger in this manner allow the bypass to be set without powering up the STP? I'm still stuck on the idea of only powering up the STP when I want to listen to two channel music and leaving the STP powered off when watching video.

EJ,

I see on your site that W4S will be releasing a integrated amp. Any idea on when it will be available? Will it be similar in specs to the STP? What will the amp section be based on and what will the power ratings be?

Thanks, Bill

Is there a post I missed for more information on the new STP pre-amp? I am super curious to see and hear more about this unit. Any additional links or photos yet?

What a garbage post!!

Emotiva and AV123 make quality products, they may have production issues ( I will be the first to say AV123 did screw up in the past year) but the designs are sound and the parts/build when done right is very, very good. I doubt you have much of an idea of what really is done by each company, I doubt you have built nothing and you are just a troll looking for a sound bite!

On the other end of the scale AV products with high $$$ tend to be more about profit margins then truely better designed/better overall products so be my guest if you want to justify your wasteful spending by thinking that when you spend big $$$ you are getting quality product but we both know who the idiot is here

I have owned them all, Salk included so do not even bother to think you know anything!

So, if they didn't screw up and had parts/build that were done right would that be a company that had super-duper quality? I built an outside storage for garbage cans

Hello TitanFan,

Yes, essentially that is what the unit should do. The unit can be powered up manually (or with the remote) to listen to 2ch, or the DC trigger will activate the HT mode when the surround receiver tells it to.

Hello Bill,

We are currently working on the integrated amps. We are hoping to have these units available by the end of Feb, but I have a feeling that it will realistically be in March.

The units will consist of a combination of our stereo unit with a portion of the preamp circuitry. There will be at least 1 set of balanced inputs, and 3 set of RCA inputs as well as an AUX out. At this point, we are going to offer the ST-500 and 1000 versions of the integrated. We may also come out with an entry model using the ASX modules, but still to be decided.

Thank you,

Since my mono amps, of course without a remote, have DC triggers in, the STP has to be on inorder to switch those power amps on as well, correct?

Can you program STP's DC trigger in so that when I turn on my AVR/processor, it can actviate HT bypass AND powering up the amps without waking up the preamp? When I want 2channel music only, I just turn on STP with its remote and the monos will be turned on via DC triggers. Or is this too complicated and confusing? :P

Thanks

Hello Klao,

Yes, the STP will activate the DC trigger outputs when the unit is on, and when in HT Bypass mode. When in HT Bypass mode, the STP will have a dim display saying HT Bypass, and none of the controls will work. It will essentially be in lockdown with only the HT feature and trigger outputs activated until the DC trigger input is turned off via the AVR/processor. Once the Trigger input goes away (processor off) the preamp will go back to normal operation mode.

I previously mentioned to EJ that the AV123 is actually the work of GR Research. Danny, the owner, is great over at their forum and there's lot's to think about with current designs. For those wishing to stay with lower power ranges (ST250), many projects at this site are highly efficient, full range, or OB design. This forum is a good read. Enjoy !
