the only problem w/getting a melos sha-gold is it will likely end up in yer *main* system, cuz it's such a nice preamp! ;~) the headfone amp is universally regarded as one of, if not *the* best headfone amps out there. another lower-cost option for a bedroom system would be the melos sha-1 - basically the same unit as the sha-gold, but only 3 inputs, (the sha-gold has 6 inputs), and half the price. all these units can be serviced & upgraded by melos audio restorations: melosaudio.com
