Should I upgrade my adcom 750 w/black gate caps

save the green and buy the good one,changing the cap wont make the magic.

Are you talking about an Adcom GCD-750 or the GFP-750? If it is the GFP-750, do you use it in active or passive mode? Sean

I'm talking about the preamp. I use active mode all the time.
Thanhn,

What would you suggest used on audiogon with $1000.00 spending cash.

I can't comment personally on the Black Gate upgrade but at the $ 1000 dollar mark very few preamps will compare w/ the GFP-750. If you can live w/o the convenience of the remote
and HT pass through, than you may want to look at the Audible Illusion M3A or if you don't have a need for vinyl their L1 preamp. For a little more green than you could pick up an older Sonic Frontiers SFL2.
Good luck...
