I've heard the Art Audios would make a nice combination if you have the $$. I've also pondered whether the Atma-Sphere M60's might be a good alternative... although not quite the 300B sound, they could bring that clean OTL and single ended effect [with some extra oomph] to an already sensitive speaker... could be a flattering combo. Might also consider the Joule - Electra OTL's or possibly the Stargates... for the same reasons as the Atma-Sphere. I too have Sonatas and have been contemplating all the interesting amplifier options I have. It's nice having "amp friendly" speakers isn't it? I'll be curious about your audition findings. Happy hunting and good listening.
best SET amp for Sonatas
I am currently running a Jolida EL-34 PP integrated with my Silverline Sonatas and have the bug to upgrade the power. Any advice on SET amps which will work well with this speaker (mk I Sonata at 93.5 db). I have heard good things about Cary 300b and the sonatas. My music tastes range from female vocals to Jazz, Blues, Rock. thanks for your help.
