Sopra 2 Amp Recommendation

Inhave bothe BHK250 and 300’s on mine. Both are great. Better with 300’s. I got mine for under 7k used. 

I had the sopra 2 and a JL 113v2 with the JL CR1 crossover. I ran them with a Pass 250.8 and a Pass XP10 pre amp. They sounded just ok to me and previously I’d had the Pass gear running Focal 1038 BE (which I preferred over the Sopra 2), Harbeth HLS5 S Super- which were excellent and a few other speakers. The Pass gear is neutral to warm or neutral to slightly dark I find. The Sopra 2 were always too etched for me, too recessed and too constrained, not sure what the issue was, the tweeters or mid range flatness) I could never get engaged with them- I sold them and moved onto Wilson Sabrina and then Sasha 2 which sound great with the Pass set up. I think the Sopra 2 are very tricky to mate with an amp and I never figured it out - I just know that all other speakers, including other Focal sounded great with the Pass and the Sopra 2 didn’t- they were uninvolving and not warm, musical or inviting.

The Pass preamp was your weak link...they are awful and pale in comparison to their amplifiers.

I have had my Sopra 2's for 3 years, I ran them with a BHK250 until about 2 weeks ago when I upgraded to the BHK300's.  I love the sound of this combination, in my room they just sound so natural with a mid-range that makes voices sound real to my ears, and those tweeters are absolutely sweet sounding (if that makes any sense).  I don't notice a lot of heat from the amps but they are warm to the touch.  Good luck with what ever amp you end up with.

I know you want to keep your Anthem, but a used Gryphon Diablo 300 might suit you very well! It will provide a beautiful soundstage and tremendous punch. When I chose my system, it was between the Diablo and a pair of McIntosh MC6111s. (I power a pair of KEF Ref 1 Metas). I went with the 611s because they bettered the Diablo in midbass/bass, along with being warmer. However, when auditioning the Diablo, there were many jaw-dropping moments regarding bass that just made me smile and reflect on how this integrated can do this!
