In a nutshell...tubes (like some women) are high maintenance, but tubes have a sound character that some find pleasant. You should find out if you like this sound before investing a huge sum of money. Unles you just enjoy tinkering around with electronic stuff, in which case tubes are for you.
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?
