500 to spend on int.amp,help me match with gear.

At the risk of appearing self serving (I have an item up for auction here on Audiogon that would profit form the folowing recommendation) may I suggest you consider separates at this price point. Besides some technical advantages separates would permit you the opportunity to customize your system and allow for greater flexibility for future upgrades.

There is a used Nak ta3a available on gon for 400 i think.

I second the Audio Refinement, one day my friends and I compared one to a Levinson 383 ($6000) and while the Levinson was better (with B&W 803's) we were all amazed that the Audio Refinement was not only listenable but had at least 80% of the detail and tone of the Levinson. Not to mention it seemed quite powerful too.

hope this helps

I have three systems in my house. From what you are telling people, I would recommend the Acurus DIA 150. It is an int. amp that has a killer sound. They sell new for I think $1500. You can find them on AG between $500-$650.
Read about this amp and I think you will find it is a beautiful sounding amp with plenty of power to push any speaker out there.
Good Luck with your search.

I own an audio refinement now and think it is a great integrated. Others to consdier would be a Mistral, anthem INT 1 or 2. You can sometimes find them in your price range. Creek is also a good suggestion. If you don't like the harshness, I would stay away from the Rotel. Just my opinion.
