Looking for $500 integrated amp to match B&W685

Hello,

I wanted to get some opinions on the subject if I could:

I am looking for a good integrated amp to match the B&W 685 speakers. My budget is limited to $500. I know it’s difficult to buy a very good new amp for this money so my plan is to buy a used one. I don’t need an absolutely purest and cleanest sound - I like it to be soft and rich.

I had some auditioning in a couple of audio stores using my reference CD (instrumental music with some piano and a little bit of vocal). The best sound I got was from Marantz PM8001-it was soft, rich, easy to listen "velvet" sound. The NAD C325BEE sounded perhaps better in bass but for me it was too “mechanical”, less pleasant than the Marantz. The NAD C355BEE was more powerful than C325 but with same type of sound; I had an impression it’s trying to “push” sound in my ears. The Pioneer A/A6 and Pioneer A/A9 pieces were great but the sound was too bright. The Denon DRA 697 sounded bad- all instruments were in the same spots, no stereo base (all others have it).

However, the PM8001 is around $800 and I would not like to spend that much. I believe that PM8001 replaced PM7001 which has good reviews and I suppose they sound very similar. Any opinions on this or experience with Marantz PM 7001?

Or, I should consider some other integrated such as Krell, Rotel, Arcam or others (all used)? I’ve read that Rotel has a “clinical” sound compared with NAD; in this case I don’t think I like it. Cambridge Audio has bad reviews so I would not consider it. I would not like to go with used tube since I’m afraid my little daughter will grab an open tube and burn herself; in addition, they are more expensive. I listen mostly "smooth jazz", guitar music, some old disco and rock, and occasionally classics. No heavy metal, hip-hop etc.

I understand that the best way to pick a piece of equipment is to audition it. Unfortunately, there are not many audio stores in my small town and I cannot afford simply buy things for tests. So all the advices of people more experienced that I am are very appreciated.

Thanks for your help!
