Class D Amp Parts Upgrade
« on: 17 Apr 2010, 03:05 pm »
Ok now that I built this amp using basic Rat Shack stuff I think it is good enough to upgrade the wire, rca's, speaker binding posts, maybe even the ac stuff.

What do you guy's who do the diy kits, mods etc recommend for parts?
Within reasonable cost I do not want to buy $90.00 rca or binding posts.

I picked up the CMC nickel free binding posts and rca's from this ebayer. Delevered in 7 days air-mail and nice quality and sound.

There are so many choices, it's really up to you. Take a look at Partsconnexion or percyaudio
and go for what tickles you.

I like the fancy stuff for cheap. Like 16awg solid core pcocc wire for the AC connections

Doesn't make sense to spend a whole lot on binding posts unless you're going up
the chain materials-wise ($$), so maybe

http://www.partsconnexion.com/product9694.html

list is endless.

BUT imho, the best mods you can do for this amp for cheap are:

power cord:

Pangaea's super cheap cords are the rage here and on audioasylum

If you're not too green to DIY, I'm one of many fans of VHaudio's DIY power cords and interconnects

http://www.venhaus1.com/diymains.html

power supply -- swapping in some larger TS-HAs as discussed in the main thread.

power conditioning -- anything Alan Maher has is a great start. but he's on military tour 'til July : (

He's also contributed cheaper DIY methods. I have several of the 193L chokes
and they are the supershiite. :bowdown:

Anyhoos, the bottom line is replace the Shack stuff by a notch but focus on the
AC/power supply. The Class D is transparent enough to reward you for it!

Thanks for all the leads,
The ebay guy has some nice stuff, good to here about a reputable dealer at a good price
The mono crystal wire is what I here to use for the least cost, I am using a basic power cord that I cut open for the ac wire
The Alan Maher stuff looks interesting
Thanks again

Check out Vampire RCA jacks from Sonic Craft.  As for wiring, Neotech makes some nice stuff.

I ordered some 28 gage fine silver wire yesterday to make some interconnects. If I like what I hear then I am thinking about replacing the Kimber copper source wire I liberated from a extra pair of speaker wires with the silver wire with Teflon sleeve. I can try it and if it is unsatisfactory then I can put original wire back.
