I was thinking about my forays into tweaking and how different my approach is to the clocks, and thought of a good experiment for anyone one the fence who has money to burn:

First, buy two of the clocks, and try them for a week. See what you think. If they don't work out, use that 30-day money-back guarantee.

Second, read Good Sound by Laura Dearborn, and try just one of the tweaks she talks about in the book (if you haven't already) relevant to your system; the book is 20 years old, so some of the stereo tweaks aren't relevant for HT.

Personally, I saw more improvement in my system's sonic performance after reading that book years ago, making adjustments that cost me nothing, than I ever did with any other change (upgrading cables, vibe isolation, power conditioner, etc.) outside of a significant component upgrade.

Anyone tries it, let me know.
