Sounds like your friend need a DAC, integrated amplifier, and speakers.
There is a thread under Digital concerning budget DACs. Might check that one out. The DACs in the Outlaw and the Yamaha A-S801 are thought to be good also. RE the Yamaha the DAC in the 801 is may be better that that in the lessor expensive models of that series, I does have different specs. I own the A-S701 and use the DAC with my MACBook Pro with a USB/SPDIF converter as the 701 doesn't have USB input. The 801 does have USB. Both have coax and toslink. I believe the amplifcation in both the 701 and 801 are the same (100wpc). I also own a NAD C356BEE (80wpc) integrated which lacks DAC and phonostage. It has a warmer sound than the Yamaha, as does the C326BEE (50wpc) which I once owned. The aforementioned amplifiers were used in my secondary system which had a retail price around $2000. All bought used though nearly new. I am currently driving a pair of B&W CM5s ($1500 when new) with the 701 and am pleased with that combination. This secondary system is a revolving door.
Would your friend consider used components?
