Ted, thanks for joining in. I did in fact at one point try hardwiring, and removed the small PC board and hardwired my IXYS diodes and Panasonic FM Cap to the secondary windings in an early modified version, but because of larger physical size and the radial leads of the components I use, simply could not comfortably fit inside the MPC enclosure. Even so, I heard minimal if any improvement. I have simply never heard great improvement in hardwiring power supplies as you have described, especially when dealing with such a small 1.5 inch by 1 inch sized PC board with only a few solder points.
I HAVE however heard tremendous improvement when one hardwires SIGNAL carrying wires, such as hardwiring loudspeaker crossovers, interconnect cables inside components avoiding chassis mount RCA connectors, and hardwiring loudspeaker cables to avoid using binding posts, etc. Your brilliant ITF Bi-Wire idea would fall into this signal carrying hardwire category, eliminating a connector and solder connection. Thanks, Michael Spallone
One other point I wanted to stress, even though devilboy mentions it in his opening post, is that the tremendous sonic results I am achieving modifying stock SR MPCs, comes from replacing the 4 active diodes to IXYS ultra fast soft recovery types, and the one passive electrolytic capacitor to an extremely low impedance Panasonic FM. This is where I have found all the sonic improvement I am hearing to come from!!
A SIGNIFICANT aspect of improved performance by simply point to point hardwiring such a small power supply instead of using the tiny PC board?? I think not! Ted & I will just have to agree to disagree!
BTW I believe SRs brilliant method of Bi-Wiring is called IFT not ITF as I mistakenly wrote in my previous post, I apologize!
Very cost effictive upgrade to your original mpc's.Everything that was there with the stock ones is now if you will more enhanced in every area.Soundstage,depth,cleaner highs,better bottom end.In my opinion all this due to an improved noise floor.Once again my thanks to Michael for such an outstanding job.
