A couple of years ago I put together a tube sysem: w/ lo out cart> a step up transformer> Canary Pre> Cary 8W 300B mono blocks. As stated earlier most modern speakers dont sound the best w/ a tube system. Their are a hand full of current manufacturers that make speakers w/ a tube amplified signal in mind. I bought Klipsch corner horns. I love the sound with this system. I would NOT use them on a solid state system or with many Hi powered tube amps, 60W etc... Although rated for 100W, @ 105 db efficiency maybe even a little higher, noise can be a problem. Tube hiss, lp surface noise, etc. can add up quick. Unless your LPs are really clean and you get a stylus that can get down below the general playing area of medium to poor records, scratches can be outright brutal. Speakers around 95-98db efficient would be much more forgiving. Less detail but the trade off is worth considering.
After rolling many brands and eras of Tubes, NOS millitary, new stock, Russian, German, USA, UK, etc. I found a combination that is super quiet and really gave me that large 3D soundstage not to harsh, not to lush. Mostly USA millitary NOS tubes w/ german NOS 12AX/U7s in the phono section. With quality vinyl I am Absolutely happy. Many old stock tubes blow away any modern tube on the market in my opinion.
I have found that connecting Solid State componants such as CD players might be a bit dodgy. Unexpected buzzez, etc. quality interconnect cables really made a big difference. I really like the Cary monos. If I had it to do over I would probably get a Cary Pre with or and a cary phono pre or Jolida phono pre as well.
Anyway I hope some of that might be useful to you.
