Cheap tweaks...What would YOU reccomend?

So my previous post may have been a bit misleading and I have learned the errors of my ways :-)

Turns out the improvements I achieved was due to the additional effective mass I had added by adding a headshell weight

However - the last item . Epoxy the Denon DL103 to the headshell weight did pay huge dividends. I can see why the Zu and Soundsmith mods are so popular

Improvements included improved dynamics, a much improved sound stage and space around individual instruments.

Best $12 I've ever spent

Remove the metal cover from your tube preamp.

Never play a record with the plastic lid closed. In fact remove the lid completely.

Instead of amp stands between or behind your speakers,try this:Get a length of gray foam pipe insulation,the type that's "pipe shaped" with a slit down the length for placing around a water pipe.Cut it in 3 inch lengths and put under the amp/amps.I use 4 of them under each mono block.Really excellent isolation.I was initially going to use them for feet under maple slabs,but no need.

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!!!
