Competitive class D amp suggestions

I gather Jason Lim shut down production of the Evolution monoblocks because the Evolution STA offered 90-95% of the performance at just over half the price, so it is now their flagship product.  I can't seem to find out whether the STA uses proprietary modules or ones purchased from an OEM.

I took a chance on a used pair of Audions because they don't come up that often and I wanted to hear them.   Count me highly impressed.  Totally black background, very fast, neutral tonal balance, good spatial representation - I do think they are revolutionary.  From my perspective, the current top contenders are the AGD and Atmasphere Class D amps (Ralph, I may be giving you a call).  I would love to hear Ralph's Class D amps and the Vivaces as well. The AGD Audions sound great with my VAC Signature IIse preamp and my Tekton Encore speakers.  Have yet to feed them into my Avalon Eidelon Diamonds.

Would love to hear people's experience of the Atmasphere Class D.  From what I've heard, people who have heard them very often end up buying them, and they are flying off the shelves...

Think there may be one or two who were not blown away with AGD.

But the comments of AGD owners are unanimously raves.

If you don’t need mono blocks (and/or are not a fan of the “tube” output stage)

the stereo Tempo is uses the same technology as the mono models and is said to sound virtually the same as the Audions for $2K less.

I believe that the much more expensive Vivace also sound very much like the Audions. Just a bit more full sounding. And the top line Grande Vivace is also very similar to the lower models just another bit more full and twice the output.

If going for the upper models, the Grande Vivaces are the ones to get.

I do agree that they are revolutionary. 

I have the AGD Tempo di Gan.  It's excellent.  I too would be curious to hear it pitted against Atmasphere's amps under controlled conditions, but there really isn't anything I want to improve at the moment, so that's not a priority.  Either it, or the Audio Envy Mega PC that I put on it, took a little while to break in, but then everything snapped into place.

If anybody has the Atmasphere classD amplifiers in the Seattle area, let’s get together and do a comparison.
