The Denon POA 6600A is a flagship amplifier from a time when quality and sound came before been counters.Absolutely brilliant piece of kit, and would cost you an easy 3000 USD to replace at the same price performance ratio per amp! I have owned top line American amps and these POA 6600A's kick most of there butts. You really need to spend big money to surpass this sound quality.As for the owner complaining after owning them since the late 80's. Geewiz spend a bit of money on maintaining them already! Most parts, if not all are still readily available. Still an amazing high quality built product with audiophile sound!

re: POA-6600

My comment concerns the POA-6600A and its lifespan.I bought a pair of these mono blocks back in the late eighties...Early nineties . I was warned back then , that I might have problems with these amplifiers , but I ignored the warning . I was just to excited about these amps...The right price for an awesome piece of audio gear.

The only problem is that they were made with faulty chips/ics and nowadays there is absolutely no support...

You are taking a real big chance with these amplifiers,you could land up with an anchor and a working monoblock...Or two anchors and no music.I am sitting here wondering if I should buy a working set and use the single monoblock I am stuck with as a subwoofer amplifier...

re: POA-6600

Hello,

I have two powers amplifiers, denon POA6600A monoblocs, no problems, I think for 26 years ago.

I do reparations when are needed, just for me, only the usual problem, in outputs relays, no more problems. that are not by fault of Denon.

I am living in Portugal, here there are many people, that knows how to repair POA6600A, monoblocs.

But if you are In US, think in "Phase Linear series 700", are also very good powers....

If you do a good price I will be happy have more two, working in 230VAC

Think about it.

regards,

Manuel

re: POA-6600

What chips/IC's are you referring to? The only IC that might be a problem for replacement could be the photocoupler IC. I was a factory authorized service centre for many years and never seen a single failure. I've personally owned many sets of both the original 6600 non-nfb design and the 6600A optical class A. I can tell you just about every kind of failure with these amps and rarely were they the result of any IC.

There is a LOT of equipment with obsolete long out of production parts. In all honesty, there isn't a whole lot that can't be replaced with a suitable substitute by a competent technician in these Denon amps. The input FETs could pose a problem but again, these are rare failure items. The list of unobtanium and such grows but at this point, I'll be happy to take on these "boat anchor" POA amps :)
