Hegel H70 + Dynaudio X12 (on Dynaudio Stand 1 stands) with Supra 2.5mm speakers wires.
All my music goes into the amp from a computer, through the USB connection and the amp's internal DAC (16 bits/48KHz). The sound that comes out of this simple set up is truly amazing!
The system is in a room that's 13x6 metres. The punch and the bass these little speakers provide (without ever losing control) is unbelievable.
