My goodness Geoff. What does your gear retail for in comparison to the articles you just noted?
Any new tweaks out there?
I know we've had threads dealing with this topic but newer members may have experiences not presented thus far. 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? Or using the solder provision instead of the hold-down nuts on binding posts on the amp-side? Or going from E-I to toroid, etc.....? It would be great to hear about something new.

06-19-12: CsontosSounds interesting. Can you post a link to the video? So I would love to hear about some effective internal shielding. This is something I have not tried but have seriously considered.I've experimented a lot with internal shielding in my preamp. My first experiment was with ERS cloth. I liked it at first, but after much more experimentation, I decided it was harming things more than it was helping. The shielding I ultimately went with was a homemade sandwich comprised of 16 gauge copper, 16 gauge steel, and TI shield. I had about 20 pieces of copper and steel cut to custom sizes by a an online retailer. Then I screwed them together with the TI shield and installed them in strategic locations in the preamp (e.g. all around the power supply). I made sure each of the shields was grounded effectively to the chassis. By the time I was done, I had added over 10 pounds of weight to the preamp. I installed the various shields incrementally, so I got to hear the effects of the shielding at least 3 or 4 times. Each time, it was the same thing: a little lower noise floor, a little better resolution, slightly better harmonic accuracy. After all the shielding was in, the preamp sounded significantly better. It was a remarkably effective tweak. It was also fun. And cheap. Bryon |
