oldenough Posted March 24, 2023 Share Posted March 24, 2023 Hi all!! I've not been around the forum for the longest time. Anywhoo a question, Has anyone had any experience of Denon POA 6600 Monoblocks, I'm hoping to use them with my RF-5's. Also what is the advantage of balanced inputs? I'm going to have to use them as one of the amps has a broken RCA input. 1 Quote Link to comment Share on other sites More sharing options...
OO1 Posted March 24, 2023 Share Posted March 24, 2023 Balanced audio main advantage is less noise 1 Quote Link to comment Share on other sites More sharing options...

The Dude Posted March 24, 2023 Share Posted March 24, 2023 Good to see you again, no direct experience with those amps, but the power should provide some good overhead. There can some benefit to balanced, as OO1 has mentioned, there may be less noise, in my experience that's only over longer runs. Also in my experience, going balanced usually provides more output voltage to the amplifier allowing it to perform at its full potential (not sure if that is the correct terminology or if it even matters with those amps).

oldenough Posted March 24, 2023 Author Share Posted March 24, 2023 Thanks for the replies, and the welcome. I found these amps in a thrift store while I was travelling, I've now got home and hooked them up, they do power-up, but no output. Ah well!! Probably a bit overkill anyway, but I sure would have liked to see what 260 wpc would do for me... lol. I'll lift the lids of 'em, and see if there is anything obvious at fault. 2 Quote Link to comment Share on other sites More sharing options...
The Dude Posted March 25, 2023 Share Posted March 25, 2023 I think its odd that both units have failed. Hopefully its simple fix. Sign up at Hifiengine as it appears they may have a schematic. hfe_denon_poa-6600_schematic.pdf https://www.hifiengine.com/manual_library/denon/poa-6600.shtml 1 Quote Link to comment Share on other sites More sharing options...

I think they have sat unused for a while, both seem to have leaky capacitors. No smell or signs of any burning. I guess I'll get them to a technician to check over. 2 Quote Link to comment Share on other sites More sharing options...
