The Belles Aria Signature Integrated Amplifier

I think the Belles Aria is a fantastic amplifier that sounds better than some other integrateds I've recently owned, like Naim Supernait 2 and Hegel H190.  The Aria costs about 50% as much as these amplifiers, so it is a great value, too. I may upgrade to the Signature model but time will tell.  

Going online to the Belles/Power Modules website for more information, I was disappointed not to find any product information for the Aria Signature (other than an image) or the Virtuoso integrated.  So these products are offered for sale and the manufacturer does not provide detailed product information?  Strange.  I know, the administrative stuff gets overlooked with a small company but Belles has been around long enough to do better.   Just my opinion, of course.  Still a big fan.  

For the moment Johnny at Audio Connection can tell you about them.  David B. is too busy cranking out units, for enthusiastic customers...

I need to talk to John Rutan about the differences between the Aria and Signature. It would be nice to do an A/B comparison.
As far as Belles' website, I agree, it would be nice to get more information, but I can understand that Belles probably doesn't have the marketing budget of, say Wilson Audio or PS Audio.

Obviously the output is significantly more, 125W into 8 ohms, but my impression is that the biggest improvement is in the preamp section, where he's trickle-downed new designs that were developed while he was working on the Virtuoso preamp.

I recently had the opportunity to compare the Aria Integrated with the Signature with Johnny R. For full disclosure, I spent most of my time there (a few hours with my vinyl) with the Aria and Rogue Sphinx v3 as the Signature is outside my budget. I would definitely say that the Signature was an improvement, but I was very impressed with the Aria. 

I also much preferred the Aria to the Rogue, and as I wait for mine to be built and shipped, I can confirm that Dave B has quite a few orders to fill.
