I've paired my KAV 300i with 3 models of Sonus Faber and have been well pleased with all. The only difference was how many strands of OCOS speaker wire worked the best. I am using the Concerto Home currently and am enjoying a particularly nice soundstage.
Speakers that are matched well with Krell
I am looking for new speakers. My system is as follows. A Krell KRC-HR for a preamp, KAV250a for the amp, a KAV 300cd for my cd player, Nordost Red Dawn interconnects and Nordost Blue Heaven for my speaker wire. I am using Sonus Grand Piano speakers now. These speakers are from my dedicated home theater and I want to keep them there. Any opinions would be welcome.
