Introduction

Somebody forgot to tell the engineers

at Denon that just because you can build

a thing, doesn’t necessarily follow that you

must build that thing. The more familiar I

become with Denon flagship products, the

more I realize two things: Denon is always

the first to implement new technologies

without consideration if the end result is a

box that weighs and costs more than most

POA-A1HDCI

10 Channel Amplifier

Review

Review by Gene DellaSala of Audioholics.com

mere mortals can swing. Enter the new

POA-A1HDCI 10 channel amplifier whose

name may be forgettable but its momentous

stature isn’t. When I first saw the prototype

at CES two years ago, I remember thinking

I can’t believe they actually produced a

multi-channel amplifier that makes their

AVR-5805 flagship receiver feel envious.

Standing in at a hefty 132 lbs, it’s the largest

review

05.08.08

and heaviest amplifier I’ve ever tested.

When Denon shipped it to me with their

matching AVPA1-HDCI pre/pro on a large

palette, my wife was concerned where the

shipper was going to place it while I was

trying to figure out how I would hoist these

monsters up my flight of steps. The Denon

separates actually took priority in my garage

over my Acura TL, at least until I managed

to get them installed into my theater room.

I was more than a little excited to test out

the new Denon gear which I pegged as

being the hottest items to review in 2008.

Now that they had finally arrived, I wanted

to be sure they would live up to all the

hype and deliver true high end performance

one would expect from the very best

“separates” components.
