Want help for my system

go to yba ,better matching but try better cables

The YBA and Goldmund are two excellent choices. You should listen to them both in your system and make a decision based on your preference. You've already got other good components. I think the solution is pretty simple. As stated by Adsal above, you can then work on fine tuning with cables. As far as the Bryston with the YBA preamp, I am surprised by that recommendation, as they seem to me so different in nature, one being smooth, warm and relaxed, and the other, the Bryston, fast, detailed and upfront. Maybe there is a balance there, I just don't think I would go that way.

I was going to write that this is clearly a case of too many dollars chasing too few......but then it's possible that Diakonov has never heard of Milton Friedman so I won't bother

The best advice is buy mark levinson amps. And you harmonic technology cables. The levinson amps are great a 331 would cost you 2,200 on the used market and a 334 around3,000 good luck

Salut Diakanov! With all due respect for all the above, and if U like yr YBA 2 pre and yr. JM Lab Minis, partner with YBA 2HC rather than the Mimesis. This is MHO, having heard cross combination, pre & power, from the two brands. The other way round (mimesis pre, YBA 1/Passion) works well -- but, why bother? Yr YBA electronics are excellent and match JM lab well (it is rumoured that Mr Andre --YBA-- uses Utopias too...).
Regards!
