mods for Adcom GFP-750

Sean, thanks for your input. I'll remove the product names and just ask the questions in a generalized way. In terms of "bang for the buck" which components are usually better to replace in the power supply and analogue output stage circuit? Capacitors, Resistors, or diodes? Please give order of biggest improvement to least improvement. Does it pay to attach the noise damping and RFI/EMI blocking sheets to the top plate of the chassis? Thanks, Mike

I work with radio communications gear and most of my audio based "experimentation" has been on some specific power amps and mostly speakers and DIY cables. I'm currently "gutting" some preamps and will consider this to be a "learning experience" in this area. As such, i will say that there is no ONE thing in ANY design that is a cure all unless the product is really just underdesigned to begin with. From what i've found, "modding" or "tweaking" gear is kind of an accumulation of a bunch of small steps forward that add up to a long and pleasurable walk down music lane. Most of it is trial and error based and that's why it is important to be able to reverse your "mods". Even the experts run into "why doesn't this work right" type of situations. As to shielding, i would try that in your sources, especially digital. I have found that my DAC's are quite susceptible to RF based interference. Other than that, let US know what YOU find out.... : ) Sean

Obviously the individuals against mods here take a flat earth view on the issue. as a close personal friend of
Stan Warrens i have heard 100s of his mods many have been done on adcom gear and all i can say is you don`t know what your missing if you haven`t listened to one of his pieces.
If an individual knows what he`s doing and what to do it to
the result`s can be wonderful.
most of his mods are less than $300.00 and more often are around $160.00

Remember, the GFP-750 is Adcom's cost-cutting iteration of a Nelson Pass design they licensed. If you want to improve it you'd be far better off selling it for $800 and buying the real thing: a used Aleph P (with remote) for well under $2k!
Think about it. I even queried Nelson about the GFP unit, and he said he had no idea how well they pulled it off.
OTOH if you use the GFP passively, it's probably worth keeping. If you use it actively, I'd try the Aleph P. It's build quality, transparency, ultra-quietness, and 3D staging are quite remarkable...and that heavy remote oozes ergonomic
luxury! Good luck. Ern
