I jumped to tubes about 18 years ago. and I will never regret it.
Being a professional pianist and having made "live" recordings of great classical and acoustic jazz performers, AND having built and hand built soldered heathkits (component by component) as a teenager music and audiophile enthusiast... there is no more alive a sound than a tube system. Even a low-priced one. If you listen mostly to loud rock, metal or screaming singers, don't bother with tubes, just get more solid state power per channel.
If you want to hear to finesse in music then you gotta go with tubes. IF you have a friend or colleague or a hifi store (Do they still exist?), I urge you to acquire the RCA CD of Bartok Concerto for Orchestra with Fritz Reiner and the Chicago Symphony. RCA legendary producers and recording technology innovators! Sit back and listen LISTEN!
Personally I use the weytech Sapphire 300B monoblocks, and with their lowly 18 watts RMS (Yes S.E.T. 300B tubes), they rock my world every time I turn them on!
The founder and designer passed away last year. They are difficult to find on the market.
I'm keeping my pair of monoblocks
