I am considering getting the Moreplay preamp and use my existing Outlaw Audio 2200 amplifiers with it. I hear about "matching" a preamp with its amp. Is there anything I need to be concerned about ?
Spec says input impedance ">10K" so there should be no problem of impedance matching. Depending on the sensitivity of your speakers, the gain might be a little high, making for a hair-trigger volume control, but there are ways to deal with that.
