I am looking to upgrade the amplifier with either an Integrated or a power amp (Wadia recommends that the 121 hooks directly into a power amp).
I am considering used equipment (and assuming that I can resell and swap if the sound isn't what I am looking for) and have a budget of $3000 to $3500. I am looking for something that will pair well with the Proacs and leave a bit of room for growth down the road.
Due to kids, pets, etc, I am leaning towards solid state, but I haven't ruled out tubes.
I have considered: Ayre V5Xe McIntosh MC252 BAT VK-255SE (pushing the budget) Simaudio W-5 Krell S-300i
I drive my 140's with a tube Cayin 100, and VAS tube monoblocks. Great sound, great value. Both provide better sound then solid state class a Marantz mono blocks, which I still have to drive ProAc 1SC's.
Jdstrawn-ARC is widely accepted as a good match with Proac. I demoed the VSi-60 and thought the sound was thin and overly bright and there have been reliability issues with the VSi-60. IMO not in the same class as the BAT-300x. I didn't mention Pass Labs because at $3500 you would be hard pressed to find a nice 30.5 or int-30a. If you decide on a BAT-300x make sure you get a late model version(check serial#)with the 6922 tube.
I have also heard these speakers demonstrated with a Leben integrated. You should hear them with a Leben if you can. I think that is an excellent match. It has tubes, but none are exposed.
