Hey CSP+ owners... anyone else give the Valve Art 274B rectifier a try? I'm auditioning one from cryoset.com. Nice tube. Doesn't quite eclipse my current favorite RCA 5Y3GT, but it does some fun things unique to this variety.
Most significantly, the soundstage has taken on a greater 3D sense of spaciousness. It has a certain shimmery quality to it... guitar strings and voices are rendered more delicately than the straight-up visceral tone of the RCA. But overall I prefer the slightly deeper bass and rock-and-roll tone of the RCA, so it stays. But I'll keep the Valve Art for future forays into outer space.
Now if I could get the tone, bass, *and* spaciousness in one... hmmmm..... rollin' rollin' rollin' the glass...
