I do not have experience with those tubes-wish I did. Here is a post you may find helpful:

Thanks Howard,

Yea you are right. I am shooting in the dark a bit. I asumed there was a destinct sound to the tubes i.e. 211 is balanced but less bass, 300 more base and extention but gives up midrange some etc. I have alwayed used SS but the majority of audiogoners agree that SET's are more musical.

I have decided on the 99's. Have found a good price. In answer to your questions:
Types of music you listen to? Accoustic, Classical, jazz. Most everything accept rap, pop and hard rock

Will you be listening critically or having music on in the background? Critically

Size of the room? 15 x 17 x 8 with room treatments

Which speakers? DB 99

What volumes? low to loud- full range when I want it.

Type of sound you're looking for? Musical, detailed, great soundstage. Emotionally involving being # 1.

Integrated or Separates? Seperates- plan to use CD player and run directly into amps.

Budget? Outside of speakers $3,000 on amps- looking for used or dealer demo.

Hope this helps-

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!

Thanks, that helps- I certainly don't want "bloomy" and have read that eleswhere also about the 300b. Nore do I want a hugely exspensive tube to replace. If somone could chime in about the 211 that would help.

I thought I'd add my impressions of the 2A3 vs 300B into the mix. In my system the 2A3 had a soundstage that filled the entire front wall (small room). It went well beyond the speakers. I didn't find this quality pleasing because I listen to a lot of cello, either solo or duet with piano. With the 2A3 the cello appeared to be much larger than was reasonable. Small jazz groups had some of this exageration as well whereas with a symphony orchestra it was fun but still not what I've experienced at the seats that I usually purchase.

The 300B by comparison had a soundstage that was more from speaker to speaker (perhaps a bit beyond). For me, the cello was more pleasing.

Finally, for those times that you just feel like you want to get visceral with the volume, the difference between 3.5 watts and 8 watts can make all the difference.

Perhaps others can verify or counter my impressions. They're my impressions for my system in my room and may not be the same for others.

My personal favorite is the type 45 tube. It puts out 2 watts per channel. I would describe it as having a very rich timbral quality. I also use a tube preamp (with 6SN7 tubes), finding that I much prefer that to going directly to the amp. I'd describe the preamp as adding richness as well (others might describe it differently). A very nice preamp with 12au7's had a refined almost sweet sound but I preferred the 6SN7's (though I could easily live with either but not without one of them).

Good luck, you've got a lot of fun ahead of you with tubes.
