I forgot to mention. The 808i is probably a Digital Preamp. So if the sources you are considering are analog it will convert those to digital internally then back to analog (with no advantage of MRC, bass management, timing etc. that I know of). So if your running analog outputs it probably won't match a high end analog preamp.

If you think listening to music is fun, try learning an instrument.
