The price reflects market value and shipping costs. This is a digital amplifier from S.M.S.L. It's in good condition. I bought and used it as a temporary solution until I purchased the one I was aiming for, as another SMSL amplifier of mine died. It can adequately power my living room's tower speakers. I connected it to my PC in my work room and used it to drive Cambridge Audio and Audio Pro speakers. It can connect to a PC via USB, and supports connections using USB audio interfaces and USB DACs. Bluetooth connectivity is also available. Instant purchase is welcome. Please understand that this is a used item. #smsl #douk_audio #nobsound #fosi #aiyima #digital_amplifier #chinese_amplifier #FX
