Proac D48R

I would consider pre plus power (not integrated) of Macintosh or Bryston for the D48R ,it will cost you more than 5K for new but for speakers that cost around 10k do deserve better amplification maybe you can find better options in your budget at the used market than you can consider Pass lab,Audio Research, Krell,Classe act  as well .

I use the Audio Research VSi75 integrated. with Audience SX cables with my D48Rs. Sounds quite good, very musical

@heinrichmilw,
I was wondering how you have positioned your ProAcs? I am trying to find the BEST positions for them in my room which is 18X15X8. I have currently placed them about 5 feet from the back wall and 3 feet from the side wall. Both positions are approximate for now, since I am still trying to adjust to the new sound. I have also toed them per ProAc's recommendation - speakers are facing directly at listening position, with neither side of the speaker sides seen.

((((I was wondering how you have positioned your ProAcs?))

With almost a square room why not try an asymmetrical approach.
This is where you sit in almost the back corner and stare straight ahead into the front corner than each speaker goes up each wall 6 feet maybe 7 or so adjust speakers so you can see just a little of the inside wall of each Proac.
Bring speakers out into the room or push back to taste.

Thank You for letting me know JohnnyR. Not really keen on the asymmetric approach. But will move the speakers slightly away, instead of facing directly at listening position and check the results. I believe I have tried that, but will experiment more.
