Which HT reveiver to replace Nak av-10?

I would look into the Yamaha line and see what you could find at a discount...

When my AV-8 died,this is what I did and at well under half the price!

It outperformed my Nakamichi in almost every way (although setting it up was more complex, but once done it worked very well).

You'd be surprised to see how far along quality has increased for less and less bucks.

I also have heard some nice things in regard to the Denon line as well.

Good Luck!

Here's 3 letters that is very hard to beat, IMHO.
Great amplifier, ability to handle difficult loads and
a lot more bang for your buck.... N A D.

Good luck and happy listening.

The new higher end Onkyo and Denon AVR's have all the bells and whistles, support all advanced audio codecs and have lots of inputs. I have the new Onkyo 805, which can be had within your budget. You should go to AVSforum.com where there's lots of info on the latest AVR's.
