Amp advice for Avantegarde HELP


Hi guy's,

I am entering new and unchartered territory and need some real help. I had been running high powered tube amps into panels (see system) but have recently decided to try the high efficiency side of life. I had really good ideas about what worked well with my Logans but am quite a newbe on the horn thing.

At the moment I have a pair of Avantgarde Duo 2.2's upgraded with Cardas internal wiring in my room. I am using my Aesthetix Callisto signature (which seems to work very well) as a pre into a pair of Nagra VPA's. The Nagra's sound really good but are a little too noisy. I don't think I need 50 watts either. In addition, the gain structure of my system is messed up; I can only crack my preamp volume open about 3-4 notches (for full volume).

Help me with some good choices for amplifiers in the 3-4k used range? I am thinking low wattage SET is probably the way to go but don't really know the differing characteristics between 300B, 845, PX25, etc. I have always run my system balanced; are there any good sounding amps out there that fit the low power mold and are a balanced design? I obviously need something that is quiet. Also, I am not sure about what to look for to correct the gain structure (lower gain amps?, but what numbers?).

Some items on my radar right now are Wavelength Cardinal, Dehavilland 845, Art Audio Diavalo (sp?). Are these good choices? (BTW, I really like the looks/design of the Dehavilland).

Thanks for your help in advance everyone.

I had a pair of Uno's. Tried many tube amps. Finally settled on a Pass Aleph 3. I know it sounds crazy, but it sounded incredible.
Thanks for all of the input so far. I am wondering, can anyone share experience on the sonic traits of various power tubes? 300B vs. 845 vs. 2a3 etc.? Or, is there more in the design of the amplifier than the tube per se?

Forgot to mention per the Art Audio PX-25s. They are available either with a low voltage input or the std input. For your AGs, you want the low voltage input option.
Dear Chris,

I suggest looking at the Yamamoto A-08 SET based on the 45 output tube that got a rave review from 6moons. The reviewer has a pair of Duos and the sound is said to be heavenly! Brian of VenusHiFi is the US distributor.

Good luck. Welcome to the world of horn speakers in general and Avantgarde speakers in particular. There is no turning back!
I believe I have the simple solution for your problem. I have been runnung Duo 2.2s partnered with Atmasphere M60s for 5 years now. M60s are 60 watt monblocks (obviously) and I experienced the same noisiness and gain problem that you are. If you pull out the 6SN7 in V2 and replace it with a shorted 6SN7 tube socket that Ralph will make you for a nominal fee, your noise floor will be lowered by 12db and the gain profile on your preamp will benefit accordingly. V2 is the right front 6SN7 as you face the amplifier. ABout $30. and your done. I feelcertain this will solve your problem entirely. Good luck!
