First off...Congratulations Mike for getting something you have wanted for a long time. I have never heard any Soulution products in my travels, but hope to soon rectify that given the strong positive comments from a ton of people.
Alpinst: Thanks for the short technical breakdown above, but as mdp632 asked, would you (or anyone else here for that matter) like to share sonically what is so compelling to you regardless of the technical chops of said amps.
While I realize that each has their own preference and areas that they look for in components, I am assuming these amps do things that others just don't do in your eyes. For example, how do they compare sonically to Constellation, Pass XS (as mdp632 asked), the big Boulders, etc. or others you can make comparisons too. I am more looking as to what you feel are they absolute strengths. Also, what, if any weaknesses do you feel they have. From the definitions above about end-game amps, etc. I would think they don't have any in your eyes.
Finally, what are the main differences in the 700 series vs. the 500 if you can say. Is it the same "house sound" with more juice or is there more to the story. I have read the "professional reviews", but take comments here much more seriously.
Thanks for any data you are willing to share.
Like with your D'Agostino amps, the Soulution are at the pinnacle of what is possible with solid state amplification. I cannot speak to Constellation because I've never had their amp(s) in my system and from what I heard and compared at a friends, I was never impressed (very weak on bass I found). The Soulution, Pass XS 300's, Vitus, D'Agostino and Boulder amps, along with many other SOTA solid state amps offer slightly different flavors from one another, but none perceivably better than the others, just different.
As for a "house sound", I would say the Soulution amps have a touch of sweetness, with incredible bass control, amazing separation, seemingly endless dynamics and wicked transient speed. Vocals are very fleshed out. Tonality is also pitch perfect. You don't feel as though you are listening to "solid state" as there is not remanence of transistor sound. Very natural.
I don't perceive any weakness, but if you're looking for 300b midrange bloom, than a Class A typology like the Pass XS300, Boulder or Vitus amps might appeal to those looking for a more liquid midrange sound.
Soulution amps project a "10th row" experience, whereas the PASS XS300's and Vitus project a "1st row" experience.
But the speed, control, separation and sheer size of soundstage is just some of the leadership qualities of Soulution.
Mike,
What makes this brand so special? I've heard them once at an audio show but, the volume was turned down and wasn't playing material that I knew. I've always wondered do audiophiles/reviewers go nuts over the Swiss Electronics(Solutiion, Dartzeel, CH, etc) because of the higher MSRP thus one assumes these must sound better?
From my understanding it's a faster amp with a high dampning factor but, these are switched with global feedback correct? How they compare with something like an all Class A Pass Labs XS?
I don't think price is the driving factor. Soulution, CH, Dart are all building precision instruments. The build quality and sonic achievements are something that must be experienced in ones own system to be fully appreciated. That isn't to say that Pass, D'Agostino, Boulder, Ayre, etc. don't build SOTA amps - they do. But like comparing a 2016 Corvette Z06 to a 2016 Porsche 911 Turbo S, there are differences, but both are excellent with slightly different approaches.
