Which tubes? My amp can except El34, 6L6, KT88, an

As stated my amp can except El34, 6L6, KT88, and 6550's. I would like to know which would give me the best sound for my system? I am running quiksilver 135 monoblocks(which require 6 of any of the previous mentioned output tubes in each amp) into Vandersteen 5's which have a built in sub and 400 watt amp for low end connected with audioquest Kilimanjaro type speaker cable. I am not familiar with the diffrent type of tubes and sonic characteristics so all help is appreciated.

I have a pair of Vandersteen Model Five speakers with a CAD280 V12i tube amplifier with EL34 output tubes. I have it set to the triode mode for 50 watts per channel and with the Model Five built in subs there is enought power. I find the EL34 more detailed and musical in the midrange than the 6550 or KT88. Of course it is a matter of taste. If you purchase current tubes in production and not NOS you can try more than one type of tube without a significant cash outlay.

Maxgain, I have the Vandys low end set a 1 with the V12i. This maybe more of a room issue than an amplifier issue. I also used a Rives setup cd and a Radio Shack sound pressure meter to adjust the multiple subs settings. I like the EL34 tubes and retubed with NOS with excellent results. Good luck

It is my understanding that Vandersteen is offering a upgrade to the Model Fives, there is a change in the subwoofer amplifier, crossover and the midrange driver. The upgrade is around 3800.00 depending on how recent your Fives are. This came from my local dealer after he talked to Richard Vandersteen. There may be other changes as well, I only had the chance to talk with him briefly and probably didn't get all the information.
