FS: Back on the market - Great W4S Class D amp, 125 wpc, musical and involving, detailed and transparent. Partially broken-in, with about 100 hours of use. Selling my Emerald Physics CS 2.3's, and so don't need this second amp for the (bi-amped) speakers. U.S. bank check, money order or Paypal only, buyer to pay shipping, UPS from 10940. Thanks for looking.
