I have black diamond racing isolation cones. Would you recommend using them under the amp or using the supplied rubber feet?
Wow those are some serious isolation feet. I just use the supplied rubber feet and have not had an issue. My sub isn't too far away from my amp and have not any issues with vibrations or performance of the UPA-7.
Wouldn't those feet be used for a turntable or a tube amp or pre-amp?
Good Luck JD
2 Channel: Work in Progress...

Hooked the amp up last night and watched a couple of films.
The first Blu-ray I put on was The Nightmare Before Christmas to watch with my daughter (she loves the movie).
It is usually harsh on the 663 and I've had to reduce the volume mid-way due to listening fatigue.
Now all I can say is: This amp is incredible! There is NO listening fatigue! I had the amp at a decent level for the entire film and it was more spacious, more defined, more clear, and the NHT surrounds came to life like I've NEVER heard - I though I had all new speakers! The NHTs are some of the best speakers out there in high-fi land (why I bought them), and have been a fan for many years after I purchased the 12" Sub Onei.
I had a Marantz before the 663, and both did them NO justice. Let me say this again: the 663 ALWAYS sounded harsh (I have an upscale 2 channel with a really nice pre and amp that is always warm and inviting while being very detailed) and after putting on the Nine Inch Nails Blu for intance, I would be tone deaf and my ears ringing with having the db at a satisfying volume level.
This amp I would not describe as ''warm', but articulate. The channel separation is phenomenal, and the overalll SQ is comparable to many 'high-end' amps I have auditioned from Alchemist (now defunct), Krell, Rotel. Micromega, Arcam FMJ, YBA, etc.
After Nightmare/Christmas, my wife and I watched Taken (she is not impressed by this stuff, like most women). Everything was more realistic and 'Fun'. The gunshots were dynamic, the bone breaking was more ppainful, and the explosions more forceful. I have 4 NHT subs running in parallel (the 663 is 7.2 - one of the reasons I bought it) and they integrated much better (with resetting the crossover from 80 to 60hz).
And damn does it look beautiful. What a heavy bastard. The FedEx guy was sweating lol.
I'm seeing Depeche Mode in Toronto next Friday, so I will be re-watching all their concerts on DVD which with the new amp will be nothing short of amazing I'm sure.
What amazing value for the dollar. Even with the freight ($130) and exchange it only came to $900 CAD. A STEAL witnessing the build quality and more importantlly the SQ.
I have a question for you all, if I were to make another upgrade to my system, would you recommend the XPA 2 for the front L/R and let the UPA run the rest, or waiting to get the UMC 1 as a pre/pro to replace the 663? I want to say that I am thrilled with the UPA and am wondering about the law of diminishing returns if I were to get the xpa as opposed to the UMC.
As I stated earlier, I'm thrilled with the UPA and I'm not sure that another amp would do much, hence the comment about just pairing it with the UMC once it is available. I don't want to be wasting cash on another amp when my room is small and so are most of the speakers. Any comments?
Actually I just watched and listened to a couple scenes from Predator and the Nine Inch Nails Blu-ray, and I think the speakers have more that ample power. It sounds fantastic. Perhaps a lot of what the people on the forum are talking about is just "upgrade-itis"- a psychological created thing, not reality.
