Bill,
Do you guys have more than one room? In speaking with my acoustic expert (and becoming close friend) Jeff Hedback (Hedback Design), he said he was helping with some treatment in one of the rooms, I thought with the Von Schweikerts. I look forward to stopping by. Your room last year was excellent.

Hello Ted,
Looking forwad to seeing you at the show!

Yes, we are in with Von Schweikert but rather than the VR-5 Annies, Albert wanted to debut his new VR44 simi-active speakers. We are debuting the Purity Ultra GT with silver autoformer attenuation which is what this year's system was built around. It is also our debut of the Harmony buffers and Purity Power power supplies.

Jeff did our room last year and has done the room again this year.

We had to take the amps out as they were now burned in enough.

I admit the McAlisters were not up to the task as they were running in stand-by mode at the time pez was in the room
Rim (woodsyi) is here now listening. Maybe we can get pez back into the room for a second listen now that we have realized our oversight?

I wondered why that idle light was lit up.

Bill Baker · « **Reply #8 on:** 15 Oct 2011, 05:38 am »

Okay KJ, and you didn't feel it neccesary to say something

KJ · « **Reply #9 on:** 15 Oct 2011, 05:42 am »

Sorry, I left the room in search of oxygen for Joe.

woodsyi · « **Reply #10 on:** 15 Oct 2011, 06:10 am »

Ok,

I am listening and it is sounding damned good. We are listening to lonewolf's rave cd and it is good. Joe mentioned amps running in idle mode earlier. It's not idling now. Real punchy.

I have this much to say about this room once everything was dialed in.

WOW

I'm not easy to be impressed and I had to say this is the best sound I've ever heard.

Good job Joe & Bill.

...thanks for the thorough list...always very helpful...

...though very odd that the McAlister OTL's weren't mentioned, even as part of the static display....especially considering they are as big as a house, and they are sitting front row center...

Cheers

Not burned in enough? The sound doesn't change very much from that, so RUN THE CHERRIES!!! I'm sure they would give you the clean power you need

Bill, would be interested in how the Cherries sound with your new gear and in comparison to the tube amps. Hopefully this can happen and Pez/Tyson can report back?

Perhaps its a gentler, kinder way of saying the Cherry didn't meet their sonic standards?

mfsoa · « **Reply #16 on:** 15 Oct 2011, 08:23 pm »

My guess is that if Albert had brought the totally passive VR44s, it'd be a better match w/ the Cherries.

With the powered subs in the semi-active, you don't really need over a KW (I'm guessing) per side and your amp options go up.

I can understand Tommy's disappointment though - This was to be a big event in his life and his company's history.

mjosef · « **Reply #17 on:** 15 Oct 2011, 08:29 pm »

Ahhh yes, the tubes on the midrange-and-up thing, I can dig that.

KJ · « **Reply #18 on:** 15 Oct 2011, 11:08 pm »

I guess I'll state what others might be afraid to say. Let me preface this by saying I think everyone was looking forward to the new Cherries being the cat's meow in this fantastic setup. However, when they were put into play, the sound was simply piercing. Whether it was due to needing time on the clock or a matter of over powering the room, I can't really say. All I know is it was tough to bear.

I think pulling them out was the last thing the guys wanted to do, but the feedback from people walking in and out was pretty consistent.

watercourse · « **Reply #19 on:** 15 Oct 2011, 11:56 pm »

Well, at least now we know. The next question is, why did it sound so different in that setup?
