The new [janus] signature is a whole different animal. They sound just as good as the IO.
As some parts updates in the new Janus will no doubt improve the performance, no matter what is done here, the Janus will NEVER have the magic of an Io or Callisto, signature or not. So much of what is going on in the Jupiter series products is about the power supply design. And this is what gives the Jupiter products the incredible dimensionality that comes off quite flat upon returning to the Saturn series.
Kurt_Tank, I agree with the issue of the Aesthetix products not having the ultimate in a low noise floor, due to tube noise, but once the music gets going, it quickly becomes irrelevant. Many claims of noisy Aesthetix products has been the issue of the old resistors used and people not taking care to find the required quad of ultra-low-noise tubes on the input of an Io or Rhea. But I agree, even with getting the tube noise way way down, as I did with an Io and Callisto signature pair, the background was not at all "black" as it is now with the Aria preamp.
If I could only hear the Ren Sig preamp vs. the Aria. Now this would be interesting.
