I have owned both [several times].
The Parasound P/LD-2000 is overall sonically superior to the Adcom GFP-750.
I own a pair of Parasound Halo JC-1 monoblock amps, and the P/LD-2000 matches up extremely well with them.
Don't get me wrong, the Adcom is a great preamp. It is a bargain for what it does, especially used.
It is very transparent, dynamic, and detailed, and has excellent bass.
But: As Plato said, it is alittle dry and thin, has a somewhat recessed lower midrange, alittle etched and grainy on top, lacks ultimate top-end air and decay, and is somewhat dark sounding on vocals, especially in the Active Mode. It sounds sort of "HI-FI", if you catch my drift! It is alittle better in Passive Mode, but still has the same basic sonic signature. It is probably a good Class B preamp if it were rated similar to Stereophiles rankings. I do not feel that it is a Class A preamp. It does match up extremely well with the Adcom GFA-5802 power amp. Great as a matter of fact!
The Parasound P/LD-2000 is an underrated preamp! I love mine.
It is extremely detailed, extended at both frequency extremes, full-bodied, spacious, and gives true palpability to vocals and instruments.
I used to also own a Pass Labs X-2.5 and a Pass X-1, which I liked very much, but, in the end, I keep going back to the P/LD-2000. It has a certain musical "rightness" that the others lack in my system.
Results may vary in other systems and with musical tastes and priorities that differ from mine.
To each his own.
