For SF Cremona: JF Concentra 1 or Plinius 8150?


My new Sonus Faber Cremona just arrived. I have a Plinius 8150 integrated amp (and a meridian 508.24 CDP). It was perfect to drive my former Signums. But maybe not good enough for the Cremonas. Pre + power solutions are too expensive for me. As it is the new Jeff Rowland Concentra. Within this framework, a second hand Concentra I might be a good bet. Is it? Or should I keep my Plinius? Thanks.

FWIW, I have a 8200 MK.1, which started life as an 8150 (was upgraded to 8200 by the US distributor). Have read various reviews claiming 8200 MK.I is a singificant improvement over 8150, and that 8200 MK.II is a big upgrade over MK.I. These claims are unverified on my part, have not done an A/B.

But perhaps upgrading your 8150 to 8200 MK.II would provide more of a good thing?

Jeff Rowland is not a good match to Sonus Faber. I have tried 2 times, 8Ti pushing Electa Amator II, and Concentra II pushing Signum. Never get good results.

Dynaudio, Thiel and Avalon are good matches to JF.
I did the 8150 to 8200 MkII thing also. I agree with Tim. The 8200 is a fabulous integrated and, for the relatively small cost of upgrading, you couldn't do better.
