Here is a gross generality to think about. If you really like lots of details in your face and slam… then sticking with solid state and adding lots more power will tickle your fancy. However, if you want a more realistic sound (with all the details… just not in your face) and the bass more nuanced with great emotional content, then look to tubes like ARC…preamp and amp would be best. Or you can split the difference with Pass XA amp.
just for discussion's sake, and not to be argumentative with @ghdprentice, while i agree directionally with his comment above, i feel it is stated too starkly as to the difference between top-flite solid state and tube amps (details in your face or not, bass nuanced/emotional/weak, relatively)... the upper tier of solid state amps (including pass which he mentioned) but also a host of others, nicely ’split the difference’ and then some (with materially better bass response), in my own experience, compared to similarly high echelon tube amps
context: i currently own audio research ref 110, ref 75, vt100, v70, linear tube ref40 but they don’t rotate in often anymore... preference goes to agd and exposure monoblocs, hegel h20, smc/mccormack dna, belles sa30 -- speakers are big harbeths, spendors, proacs, maggies...(further sidebar: i generally don’t run my rel subs anymore... but for those that do, tube amps may well be best of both worlds...)
