I must say that once you hook up w/ an idiosyncratic sound it's hard to accept other sound. J-10 prefer's Cary/Senn to Omega II is quite understandable. Because Cary is very SWEET.
For me, I prefer RKV due to its almost perfect balance, resolution, and neutrality. For those like to try Cary, Audiogon has plenty of used but great samples for $2000. I must say that Stax betters RKV and Cary in almost all categories objectively, but somehow lacks the darn "magic" quality.
Difficult to explain but allow me to give an example. The McIntosh MR67 tuner produces a sound that I feel I prefer to some of the best sources out there including the Sony 777. The is no kidding that Sony beats crap out of MR67 in almost every category. But the sound of the vintage tuner is so open, liquid, and beautiful that I can forgo details, tolerate noise, wait for commercials, and surrender choices of music... I almost bought a 777 and glad didn't do so as nowadays I pretty much only listen to tuners.
Down to the root, it's all about personal taste and preferences. After all, this hobby is an acquired taste. Doesn't matter what other gentlemen say, I prefer brunette over blonde. Stick w/ your taste and you will find the amp you love.
