Howdy, I mated my CDM9's to the new Krell integrated, KAV-400xi. Simply phenomenal. The CDM9's dissapointed me for close to a year before I got this amp. It lacked bass response and the soundstage would literally collapse at higher volumes. Plus the system was plagued by undue sibilance. I tweaked the speakers by adding Sonic care spikes. A big improvment in bass. Then I added some decent OFC wire. Another improvement in bass. But they were still lacking. The sibilance was still prominant and the bass was woolly. I then replaced my CDP to the Rotel 1072. Better, yeah, but not greatly. Then I replaced my preamp/amp combo to this integrated. Wow. Tight controlled bass, elimination of sibilance, balanced sound at all volume levels. Clearer and more articulate too. Palpable bass even at low listening levels and seemingly limitless, distortion free power. Sounds great.
FWIW: I heard the Classe pre 35 and 101 amp combo w/ the B&W 703's (the CDM9's replacements). I couldn't tell the difference between this combo and the KAV-400xi, but my wife could, she liked the Krell much better (women tend to have better hearing). For less money I went with the integrated. A great piece. Check it out.
