Audio Research Ref 3 Preamp + Mcintosh Mc501's

Hello Primare , the most imported issue is the input impedance of the Mac 's .ARC REF 3 likes 100 to 200 kOhm ,
see the specs of the balanced power amps of ARC .The input imp of the Mac 's is 20 kOhm , you have to try , as it is possible you loose low frequencies . I 'm using BAT VK1000
monoblocks with my ARC REF 3 with excellent results.
Greetings from the Netherlands , Hans

I've known the potential mismatch issues. However, would like to know if anyone has really tried out this combo
I like the sound of AR Ref 3 but really have reliability issues with AR power amps

Thanks

Is there anyone who has tried this combo? Can you give me your feedback please?
Thanks

No concerns, they work well together I had them paired up with Eggleston Andra 2 speakers.

Connected via balanced IC's

The only way to be assured of match perfection is to get the components from the same manufacturer. I found that this gives a synergy that few if any combo might have.
