Power amp s for Avantgarde Duos?

Hi, I'm looking for new amps for my Avantgarde DUOs.
I have had different tube amps, and prefer 300B/845/805..
Now I have Cayin/Spark 9084D, 845 monoblocks; but I have some problems with hum, and they are not the best with respect to resolution.
Noise is of course a challenge with these speakers.
I have recently tested a BAT VK-75SE, and were impressed by the dynamics and the fantastic bass slam together with excellent resolution and imaging. But the midrange (vocals) seem a bit "too neutral" (analytical?) to me........
I have a BAT VK-51SE pre amp, and Acoustic Zen Silver Ref IC's, Audience Au24 speaker cables (might be replaced with AZ Double Barrel.....).
Source: Pink Triangle Anniversary TT + Wheaton TriPlanar MkVII tonearm + Lyra Titan PU, and a Pass Labs X-ONO phono stage.
Room size 3.5 m (w) x 5.5 m (l).
Price range (new or used): up to $4000.
I prefer monoblocks, but no must........

Best regards Ola

Some popular pairings are:
Viva, Lamm ML-1, Audiopax Model 88, Tom Evans Linear A and B (some folks I trust think these are the best),Tron. Probably lots of other good ones.

Top choice IMO is the Lamm ML2, but in your range look for used Audiopax 88s or Art Audio PX-25, you might get lucky and find some near that $$ level. Happy hunting!

I believe that 845 SET is not a logical choice for Avantegarde DUO's ... I would rather think in direction of good SET with 300B or 2A3. There are a lot of producers of quality SETs with these tubes. Look for example in direction Japan ... Shindo, Yamamoto, ...

Another possibility is to try Pass Labs XA 30.5. Excellent MOS-Fet A-class design.

Third possibility is to try Avantgarde mono's of 50 W in A-class. I heard them with Avantgarde Trio's and they sing together. Very expencive though ...

Hi Ola, your speakers are very sensitive towards quality amplification. I heard a pair of AVG's hooked up to Audio Note Oto SE's. The sound was simply unacceptable - not transparent enough, poor imaging, and a LOT of horn coloration. I was about to walk away, when the dealer suggested Graaf OTL. The sound was MUCH more acceptable - more neutral, detailed, and with better rhythm. I have also heard the Duo's with my old Cary 805-AE SET's. Very nice, but I preferred the sound of the Graafs.

I have not heard sound from the Avantgardes which have really impressed me, but that might be because they need better amplification than what I have heard them with. Best of luck with your quest.
