What is the best Preamp+Power Amp for Proac K6 ?

Hello Razvanvrs, I am a Proac k6 owner and I use an Accuphase E560 integrated amp with very good results. It has only 30 w per channel (pure class A) but I find it more than enough to get the Proacs singing.

I have also heard the k6 driven by very low-powered Audio Note tube amps and the sound was fantastic. So I unless you listen to music and ear-splitting levels, I wouldn't worry too much about having lots of power.

Basically I believe the ribbon tweeter used in the k6 needs to be matched with a tube or class A to maximize its performance.

Hope this helps. Good luck!

PS if you still want a pre power combo, try the class A ones from Accuphase.

I am driving my ProAC K6 with Conrad Johnson ACT2 Preamp and Conrad Johnson LP140M PowerAmp with good result. My sources are: Audio Aero Capitol Reference SE CDP and Micro Seiki RX500 (Turntable) + Moerch DP8 Tonarm + Benz Micro Ebony Cartridge. All cables are Audiance.

I have the K6's, which I love, and have paired them with the Octave MRE 220 monoblocks.  A superb pairing.  The strength and beauty of the K6's is their planar like alignment and coherence.  They do a terrific disappearing act and have ample bottom end in medium sized rooms (e.g. 14'x 16'), with solid gear.  I had the Ayre MRX's but was diappointed with the bass and highs.  Admittedly the mids were luxious and real, but the Octaves give me everything now and better.
