Amp s to drive JM Lab Diva Utopia Be


Hi Folks:
I'm enjoying a newly acquired pair of Diva Utopia Be speakers. I'm wondering what are some good amp choices for these speakers? I'm currently using a pair of KR tube amps that provide about 28wpc. I like the sound a lot but am wondering if I need to take the plunge and get some serious solid state power, or whether I have what it takes with my KR amps. Contenders I've considered include YBA 1 (or maybe YBA 2?), Pass Labs 350.5 or Parasound JC1 monos, Bryston 4bsst, or stick with tubes but get some more serious push-pull power from Canary Audio, BAT, Cary or some other..

Anyway, I'd welcome advice. I'm used a few other speakers but main set of speakers I've used for the last few years were AP Virgo II. I found the upgrade from the Virgo to the Diva to be surprisingly small, but I do hear it. The Divas certainly have more bottem-end extension, a wider sweet-spot, and overall have more weight and presence, but the Virgos did have pinpoint imaging that really did make them disappear - I sort of miss that strange effect.

Thanks in advance or amp recommendations.

Aball, the 9SE's are quite smooth and they were just released so there is no press or reviews available on that model as yet. But thanks for your opinion and concern.

The 9SEs, so far, have no weaknesses that I can detect. They are quite a bit better, than any other amps I have ever had in my system. Perhaps, over time, I might be able to spot some extremely minor weakness, but for now I hear only the great strengths of these incredible amplifiers. If they have any weaknesses they must be extremely difficult to detect, because I sure don't hear any -- and the VMPS RM30 speakers I use are quite revealing, as well. No other amplifiers have allowed them to sound nearly this excellent.
Guys, thanks for the input so far. I have heard of those Nuforce amps, and they do seem intriguing. The price seems quite affordable too. I may look into them.
I use a Bryston 4b-ST to power my 927Be's. It is a very good match IMO. The 4b-SST should be even better. I have also heard BAT gear on JM Labs speakers. I was on the floor with that combo.
Plato - HiFi+ magazine, issue 42, Reference 9 monoblocks. But maybe the 9SEs are completely different.
I have the JM Labs Ato Be.I drive them with Chapter Audio gear and also a Hegel 300 watter.And I have heard them with solid state amps and tube pre.Now that was also glorious.
