Nce discussions here, I’m tempted to try ATC SCM11 v2, as it’s best affordable and fit option for me, I need the speakers to play music in a more forgiving way, but articulate at the same time? Does this speakers need tube to sound musical? Currently, I got 3 amps, Marantz PM6005, Class D Audio SDS-400C, Yamaha A-S801, the Marantz is the less power but easy match with bookshelf speakers, most probably not enough to drive the ATC? I’m using Fostex HP-A3 as DAC/preamp, works well with a pair Wharfedale Diamond 9.1. The Class D Audio sound best for bass control and treble would be very much depend on speakers and source, last the Yamaha is most probably the hardest to matched a speakers, the bass sound boxy from Wharfedale Diamond 9.1, I’m not sure how well the Yamaha can drive an ATC?
