This is not just another gainclone

I believe the people who suggested this didn't try it out in a real environment. Instead of speculating, build it, connect low capacitance, then big capacitance and let your ears decide. It is that simple.

I used to built stuff by choosing parts according to my likening. I used to think: this part looks good, so it must sound good too. I never bothered to to listen. Recently I started to listen when choosing parts. And it makes all the differnce.

I checked my original PS yesterday and MUR860 from Motorola seems to be even better than MUR1520 from IR. And adding 4.7 BG N beside the bridge definitely improves highs (less harsh). Placing 1000u BG right after bridge degrades sound. 1000U BG on ea. rail per chip is definitely enough in certain gainclone arrangements.

My PS wiring is different. I run ea. secondary to a separate bridge. Secondaries and bridges are not connected inside the PS. I also run separate grounds for + and - rails and they connect only at amps star ground. According to your schematic there is no reason to run separate ground wire for + and - rail, because they are common (connected at PS).

You have $45USD for Cardas speaker cable. What is it for?

[Algar_emi]

I was expecting to use short lenght pf Cardas Crosslink speaker cable for the Power cable between the power supply and the Amp. This is the only OFC copper cable that I can easily get. Price is around 8$ per feet.

FYI, wirewrap wire is OFC and is readily available.

Oh, and considerably less than $8 a foot.

$8 a foot is definitely too expensive and probably not practical as well. I'm using Kimber 4TC which has exactly 8 wires, some of my friends actually prefer regular silver plated copper hook up wire (teflon) to Kimber as having more body and better tonal balance. Also Cat 5 cable might be a good alternative.

Hi Peter. Thanks for the precision on the power supply. One reason I did this schematic was to compiled all the comments on your Desing in this post. Check this version and tell me if I got your explanations correctly. Let me know if there is any other changes to do.

[Algar_emi]

Thanks for your comment on the Wire. Peter, do you know a distributor of Kimber 4TC and also the price so I can update the parts list.
