Thanks guys for providing new answers which they make a total sense to me.
I've read a lot about comparison between different gear and now some of your arguments comes into place and that makes better understanding to me about the sound. I heard McIntosh MA7000 on Sonus Faber Electa Amator II but I did not made any conclusions at that time as it was to short to make them. Sound was pleasant and very listenable, but still I asked myself and told to my friend that his Gryphon Tabu might be even better sounding than this sexy MA7000. If I would be greedy I would be able to live with any of them I think :).
I also found some comments of users on other forums in regards comparison between Jeff Rowland Continuum 500 and MA7000 and there are similar conclusions than here. The only problem I had was to find comparison that we talk now here -> Gryphon vs McIntosh. Only on one Italian forum I helped myself to find some comparison comments between Diablo and MA7000. Users there were mentioning some veil in the Mac's presentation. But it was not defined as something ultimately bad but rather as a tubby sound or musical forgiveness by my interpretation :). Also MA6600 was judged as a good alternative with maybe event better balance of sound than MA7000. But this again I think is much more of a finesse and associated with the equipment used I believe. I found this last mentioned discussion on Audiokarma forums. But my preference would be to discover MA7000 prior to MA6600 more as of technical advantage of the amp.
And finally Diablo on Italian forum was mentioned again as strong, full controlled with excellent transparency and for some better sounding than McIntosh MA7000.
If I go back to my experience with Gryphon Tabu and its bass area. It was simply excellent that is how I remember it with great energy and push. Gryphon just drove my speakers like no amp before or after. Even at low volume speakers still sang so good and with a great body. The only problem as said was first hour as Gryphon Tabu was sounding good, but nothing extra special. Magic came alive after 45 minutes or something.
Coz of the age of Gryphon Tabu I'm now leaning my curiosity towards Gryphon Atilla. Atilla is an entry level Gryphon integrated with 2x100W. It is a proper dimension for my place as I don't need more power for my place. It has also HT bypass that I need and there is a word that it is also a bit more forgiving than Diablo and that maybe can work very well for my system?!? Now a challenge how to find a piece to test it and to confirm this. But Ok I'm not rushing anywhere. How much better can Atilla be in comparison to Tabu? Is it possible to be better sounding at all? Technically certainly, but still I wonder what the reality can show. If weight is the main factor for judgment of the quality then Gryphon Tabu would outperform Atilla by around 8kg. What about the sound?
