Amplifier for Q acoustics concept 500


Hi to all.

I own the title’s speakers. I have paired them with harman kardon hk 990 but I don’t like the combination.

I tried a friend’s cambridge audio cxa80 and the result was much more pleasing, so pleasing that maybe I could live with it.

But I want to do better because I think these speakers deserve better amplification.

My budget is about 2.000 euros for second hand. I was thinking for cambridge audio 851a if its’ a step up from cxa80...since I already liked cxa80.

I could also find Hegel h190 and marantz pm-ki ruby for 2k and I wonder if they worth over Cambridge audio which is very transparent. One think I don’t like about harman kardon is that is has a bit dark presentation even its power is effortless. Pairing with cambridge audio, the speakers had very good bass extension as with hk 990 too, but sounded more airy compared to harman.

If someone owns these speakers and has a suggestion for which amp will suit them best I would appreciate it.

The source is a marantz tt15-s1 and I also use the internal hk 990 dac to listen from Spotify and macbook.

My primary concern is to find a suitable amp and then I can add an external dac and phono if they are not onboard.

Thank you in advance.

I also own the concept 500. I paired them with Mcintosh Ma252 and Moon 600i.
Since the 600i is a fantastic amplifier, it sounds better than the Mcintosh gear by far.
Been said that, you could try a used 600i but I’m afraid it will be out of your price range.
You could try a used Marantz PM11S3, which I liked more than Marantz Ruby or PM10.
Another option that can surprise you is a Gato Audio DIA-250S from Denmark, which now is 40% off factory direct with shipping and taxes included for 2.495 euros. One hell of an integrated more close to the high end amplifiers that you can imagine, and with DAC included that sounds like a 2.000 euros one. I have no affiliation with them, just like their gear. I will try this combination with Concept 500 shortly. 
Forgot to mention. Hegel h360 or h390 also will be a perfect match with Concept 500. Better than Ruby to my taste.

It's not that I do not like ruby. Ruby pairs very well with concepts.

But I will always try to find the best possible amplification for my speakers.

Maybe in the future I'll try more amps to pair  with concepts which i find them absolute;y great speakers. I listened more expensive speakers but overall i found concepts exceptional in their price range or above.
