Pioneer make an adaptor, Part No. CD-RB20, which allows you to feed an external source into any 'P' series head unit via the IP bus. This should work OK with the Empeg but, you might have to reduce the Empeg's signal level by fitting resistors in line, as the adaptor's probably not designed for the sort of signal level the Empeg can kick out, and you might also have problems with noise - Pioneer's latest units seem to be a lot more prone to floating ground problems than most other units, and in combination with the Empeg's floating ground output stages, it could cause a few headaches. Definitely worth considering though, especially as it'd mean not only keeping your existing unit, but also avoiding the need for external amps.
