Cary CAD-805C driving horn speakers?


I have an opportunity to purchase a pair of used Cary CAD-805C 50 wat mono block amplifiers. I'm wondering if anyone has tried these amps with horn speakers, specificly Avantgarde. Are these amps too noisy? Is the sonic signature not a good match for horn speakers? Any advice is most welcome.

These amps are really 25W class A with the ability to put out 50w in A1 mode. They are dead quiet and very nice. I have not heard these amps with Avantgardes, but I have heard them on other high eff horns and they sounded nice. If you do buy the 805C, I would look at getting them re-capped with Mundorf Gold / Silver and oil caps...WOW!
I've used my 805Cs with high sensitivity Zingali horns without any noise issues. The amps will change character with your choice of output tubes, though - despite the consistent specs of 845s and 211s. IME, the former take things a bit "dark", while the latter tilt toward a more "forward" presentation. The effect has been pretty consistent and you should consider trying both tubes with your speakers to see which you prefer.
Interesting question. A couple of years ago I was considering the Avantgarde Duo and lugged my Cary 805AE's into a dealer for a listen. There were more than a few issues with the way the dealer set up the speaker - room too small, did not get a good match between the subwoofer and the horns, etc. But I discovered that the amp was a very good match for the speaker.

I got to listen to another Avantgarde with a variety of different amps, and was surprised by how sensitive these speakers are for quality amplification. An Audio Note Oto SE simply sounded dull and lifeless. A Graaf 20W OTL sounded much better - more detail and better dynamics, but was a bit too forward.

The Cary 805AE was in a different room, so not strictly comparable. But the dynamics were something else - VERY impressive. The tone was typical Cary 805 - a touch on the bright side, magical top end, and very sweet.

I am not sure how the 805C compares to the 805AE, but I think it would be a good match.
