In regards to the Black Gate capacitor mod to the Adcom GFP-750, ask audiogon.com members 'Lmack' and 'Mitch2' about it.I think both of them had this mod done to the Adcom GFP-750's at one time or another.
Should I upgrade my adcom 750 w/black gate caps
Has anyone heard or have owned a modded adcom 750 w/black gate caps upgrade. Is it worth the money. And how does the mod sound after a few weeks of break in compared with a regular adcom 750. Also looking in to upgrading my amp with a Parasound Halo A21. Has anyone heard this combo? Any thoughts? Any info would be great.
