Amplifier Recommendation for Spendor D9.2 Speakers
Currently driving them with a McIntosh MC275 VI and wondering especially if solid state might do a better job. Can anyone share their satisfying amplifier experiences with Spendor D9.2's? What works best for you and why? I listen to a wide variety of music so hard to pinpoint where I'd like to concentrate in that regard. Open to mono and stereo amps up to $12K total, and open to pre-owned.
