Advice going from SS to tubes?


Hi all, I'm considering going from SS to tubes. For me, this means changing speakers (currently Usher 6381) to more efficient designs, and of course buying a quality tube amp(s). I have a Shindo Auriges L preamp that I like very much, so I'll hold onto that for now and see if I can work it into the new system.

My musical tastes are rock, acoustic male/female, blues and soul. I need a set up that is dynamic with good bass. So I think I'm leaning toward floor standing speakers (the Auriges does not have a sub out, and I don't have a very musical sub anyway).

My general question is, what things should I think about when making the switch? I'm aware of some of the maintenance issues with tube amps, I want a good one, but would rather have fewer tubes as opposed to many.

The other question relates to specifics: any speaker recommendations? amp recommendations?... speaker/amp/preamp combinations?...

If there are other threads on this subject pls link provide links. Thanks in advance for any and all advice.

I should add my total budget for speakers and amp is $3-4k, room is around 12' x 18' x 12' (decent sized, not huge). Source is strictly cd.
I recently bought a Rogue Audio Tempest II Magnum and a pair of Tyler Acoustics 7U speakers here on Audiogon. This is my first tube amp and it sounds wonderful. I was using Paradigm Monitor 7 speakers and it sounded good but when I put the Tyler's in, it went from good to fabulous!! I got both pieces for less than $3000.00 inc. shipping. The MSRP is $6595.00 not inc. shipping. As far as maintenance, I have been told to check output tube bias about every 6 months and adjust it only if more than 10% off from factory recomendations. This is not set in stone just a good starting point. Some tube savvy members here can probably give more technical advice. I do know this,tubes need to warm up before they sound their best. I find about an hour of warm-up before serious listening is good for my system. I have to admit that I have had good luck in buying my equipment without the benefit of hearing it first. I suggest you listen to some different tube equipment and speakers if you can. I wish you luck in your search.
I've heard PSB Synchrony speaks sound really good on a modest but very nice system using a Rogue tube power amp.
