I'm new at this so please excuse my ignorance. I recently bought my first sound system. I have a Rega Brio-R amp and Monitor Audio silver RX-1 and I have a sonos ZP90 plugged into the amp. I'm a little disappointed with the sound and obviously have no way of adjusting the bass/treble etc. A friend suggested either getting a DAC or a USB audio interface. I'm totally clueless, and don't have a lot to spend. Does anyone have a suggestion for a cheap DAC or usb interface that might improve my setup?
Thanks in advance!
