Tube amps don't require herculean efforts nor advanced degrees, but they do require one to use sufficiently appropriate speakers in order to achieve a listening experience that goes far beyond what you've experienced with SS, though many would disagree. It's the best audio move I ever made, and I don't intend to return to SS. Lots of nice amps available, so do some web research, do some Googling, check out some of the Audiogon virtual systems.
Tube or not to tube?
I am new to the hobby and would like some input. I am seriously considering moving to a tube-integrated amp (new or used)like the PrimaLuna II or the Jolida 502. Currently I have the NAD Combo 162/272. Would I be upgrading my system with either of the tubes? Or am I just moving sideways?
