Antelope Eclipse 384 AD/DAC and preamp


Have anybody experiences with this phenomenal unit as converter or processor or just as preamp?
breezer
Antelope audio does not recommend to use Eclipse384 with preamplifier, because it will affect the signal/noise
But it is itself a preamp. Maybe with not many analogue inputs, but a genuine analogue/digital "central point" of a system, even of a nice highend home system.
Or in´t it?
