That definitely helps, Tickfight. I can certainly convey my impressions of the 2A3 and the 300B, having owned both. I am not familiar with the sound of the 211 or the 845. The other power tubes I have either owned or heard extensively are the KT88, EL34, 6550, 6C33C, PX25--all in a push/pull format, except the PX25 (SET).
With your musical tastes, room size, and speaker choice, I would highly recommend SET amps. You have sufficient bass response from your active woofers, so no worries about the bass extension of the amps. As well, the 99dB speakers can be powered by very low wattage. The only choice really is what type of midrange sound you want.
I find the 2A3 to be an honest sounding tube. It is accurate, detailed, airy, without any frequency exaggeration. From the listening position, it begs you to find fault with it. I feel that if there's something more I want from a 2A3 amp, it's a matter of personal preference, not an issue of musical accuracy. The 300B has a more bloomy sounding midrange, almost milky to my ear. It has an incredibly blissful sound, and sounds good no matter where you are in the room, or in the house. I've come to believe it to sound falsely lush and holographic, not at all as a measure of good or bad, but simply exuding an effect that sounds more an attribute of the tube than of the music itself. It is seductive and inviting, but IMO it is exaggeratedly so. For some, it can be just the ticket. It's hard to listen to a 300B and not feel like you're getting a sonic massage.
I did actually hear one 845 tube amp, and wasn't enamored with it. It ran exceptionally hot as well. If I'm not mistaken, I think that NOS tube rolling for that type can run in the thousands of $$$.
If you can listen to some different amps, that would be best. Some manufacturers offer trial periods, and for $3K, you can certainly find some excellent products out there. I'm sure some others can chime in--or search the archives--as to the many options available. Again, with your preferences in music, I think you will find yourself closest to the music with SET amps. Just my opinion, of course.
Enjoy!
