Any new tweaks out there?

Jmcgrogan2 beat me to it. The tweaks and ads from Coconut Audio are the only ones coming to my mind.

I have enjoyed some the tweaks that Elizabeth has mentioned. I did a combination of them. It was speaker wire with ferrite cores and a 6 volt lantern battery with a 1000u cap across the top. Ugly but the results sounded pretty nice in one system I had them in.

Yeah right. Coconuts make me think of monkeys. By the looks of those photos, I think Darwin may have been right about the missing link. I remember that thread about Elizabeth's tweak. But I'm not really interested in relatively insignificant tweaks. If you want to meet someone who would do anything to improve his gear, you just did. So I'm past all the gimicky debatable stuff. I'm into the kinds of things I mentioned initially. Stuff a capable non-tech can accomplish with limited technical knowledge, or even higher level tasks with direction by someone in the know. This is not after all, rocket science. As an example, If you do endeavor to upgrade your amp's power supply wiring to at least 8awg consisting of around 500 strands of copper, your going to experience a very pleasant surprise. Why manufacturers insist on building a bottleneck into the amp, I don't know. If you do this, It will sound like it just became a much more expensive amp.

I have used a combination of a memory foam pillow with a board on top to allow for ventilation and leveling. It is an incredible good at dampening any vibration my preamp is ezposed to. It can be bought in sheet form from some fabric/sewing shops. BTW it is also called visco-elastic foam.

That is clever, Mechans.

For instance, I'm sure many of us have noticed the the skimpy 12-14awg leads on the power supply of our amps. Has anyone tried replacing them with say, 8awg just to see what happens? Or changing out main caps? Or changing to pure silver signal wire?

Yes to all of the above, more or less. I recently changed the wire connecting the IEC to the power supply in my preamp. I replaced the generic small gauge wire with silver plated wire from DH Labs. It was a nice little improvement, and easy enough if you can solder. My preamp also has upgraded caps and solid silver wire at key points.

I'm a compulsive tweaker. You can see a list of the tweaks I've tried here. I'm happy to discuss which were the most audible in my system, if you're interested.
