I have the ProAc 2.5's paired with CJ Premiere 12 amps and love the sound. Its very smooth and sweet, and produces a huge, well defined soundstage. The system does lean a little to the warm side (my preference), but not enough to take away from the speaker's natural liveliness. A great match for orchestral, jazz and folk music (my tastes), adequate for rock and techno. These speakers have the ability to sound good with a variety of electronics, although the best reviews I've seen have been with tube components. They tend to take on the characteristics of the amp driving them and do a very good job of matching that sound. You'll find that they match up well with AR electronics (where they are brighter and more aggressive) as well as CJ (as described above). Your tastes will determine which one's work the best for you. Try them with CJ amps and I think you'll find that they're an outstanding match, especially with the type of music you like. Enjoy...
ARC Amp for ProAc Response 2.5?
I am looking for an amp to drive my ProAc Response 2.5. My system consists of Theta Data II Transport, Audio Synthesis DAX Dac and Conrad Johnson Premier 2 preamp. Interconnects are Nordost Red Dawn and speaker cable Nordost Blue Heaven. I have found an Audio Research D125 and a D115 in a second shop and wonder which will be a better amp for my Response 2.5, or there are other better matches. I generally listen to vocal and orchestra music.
