Cheap tweaks...What would YOU reccomend?

I checked out Rick Schultz of EVS audio's web site after reading about him here on Audiogon. He makes something called a ground enhancer, their $30 a pair with a money back guarantee. I got a pair yesterday, they just hook onto the neg. speaker connection on each speaker. Very easy to take on & off to compare, they work as advertised!!! They improve everything.
When my wife came home I had her sit & listen to a Dianna Krall track then I removed them & replayed the track, she said the vocal was more open sounding the 1st time & she had no idea what I had done.
After a few hours there was even more improvement.
Well worth the 30 bucks!!!

Billgaw, there are several manufacturers of such devices. I have tried those by Exemplar and found they had a very nice improvement. When I got Rick Schultz's High Fidelity series of cables, I accidentally noted that without the Loops, the sound was better.

This is but one of several instances where I noted tweaks that worked with other cabling did not work with HFC's "magnetic conduction." I wonder if these use "magnetic conduction."

Opps, I've learned it is not the Rick Schultz of High Fidelity Cables.

Romex Power Cord - 8 feet long

Since there are a few post in Agon that mention this I thought I'd give it a try.

Had some 12 gauge cable lying around - the 4 conductor stuff used for two-way light switching.

Stripped off the sheathing and removed the bare earth wire leaving me with three insulated conductors - I used the red for earth

Figured I'd better braid them to keep noise/hum to a minimum.

Soldered Spade terminals on the ends so the mains connectors had lots of surface area to bind to.

Attached some gold/copper mains conectors like these

All parts cost about $35 and a couple of hours of my time

Results...
> Not quite as quiet as my Furutech, but required full volume to hear anything
> More dynamic and spacious than my Furutech 15 gauge
> Almost as good as my Furutech 10 gauge

Hard to believe? well it brings power to your outlet doesn't it?

RE: the trivial noise issue
- first I had to crank the volume to full and put my ear to the speaker in order to hear it
- I believe this is due to my less than stellar braiding
- get the conductors the same length and tighten the braid and the issue probably goes away

I didn't expect it to be quite this good - should be even better once burned-in

For the 8ft braided length I used approx. 9.5 ft of Romex

Only issue is it's bit springy - but it does support itself - no sagging at the outlet :-)

Wanna try a new power cord, but the cost is putting you off? Try this tweak - something to do on those cold winter nights :-)

Update - tried a 10 gauge romex power cord today.

Tough to braid - but sounds great and definitely worth the effort

Put the 12 gauge on my sources

I guess it's the same as plugging everything i to the wall outlet really.
