    "I was using a Primaluna EVO 300 tube amp, although it drove them IMO it was taking a lot out the tubes. ...I added this Rotel amp to my Denon AVR-X6400H receiver to supply more power to my B&W CM10 S2 main speakers. While the Denon did a good job, the 200w per channel Rotel has really opened the soundstage and allowed the B&W to really "sing" (pun intended). "
