I accidentally left my review in the 2500 section but i actually have a Onkyo 4500 mk2.Its paired with an Onkyo cd player and A/D/S L 880 speakers.It sounds great,it took the place of a Marantz 2252b,to my ears,with these speakers it just sounds better.I was surprised, they are underrated.I have heard the 4500 mk 2 was one of Onkyo's best,i'm starting to believe!I had to replace a few bulbs,a common problem with these units,but not to difficult.

These Onkyo receivers often get lost in the admiration for Marantz and Pioneer but they really hold their own. I own a TX-4500 MKII and find that it is clear and crisp with great separation. I also enjoy the three tape inputs so I can run computer, TV and MP3 all at the same time. The two phono makes it easy to compare sound from two different turntables easily.

re: TX-4500

I bought a new TX-4500 in 1977 when a pay-raise came through. What sold me compared to the others in its price-range were:
- three sets of speakers (even though it would only play A-B or A-C at a time)
- three tape inputs (!) - I had a reel-to-reel and two cassette desks and could copy a reel to two cassettes simultaneously
- the Quartz-Lock tuning

A couple of years later I was in Germany and at the post audio club I found a JVC graphic equalizer with 12 or 14 sliders on each side. It fit into the system in place of the Dolby NR perfectly, without taking up a Tape or AUX slot.

The 4500 eventually yielded to an integrated set of Pioneer components in the late 90s. One "problem" with the Onkyo was the size. At almost 22" wide it was hard to find furniture it and the other gear would fit into. I also down-sized my speakers to a Cambridge Soundworks satellite/subwoofer setup (Ensemble II) which I am still using today, almost 20 years later.

I have my eye on a TX-4500 II in eBay and may have it by the end of the week if the other bidder doesn't go nuts. If I win I'll report back here.
