Best current footers for preamps?

I used to endorse Herbie's Tenderfeet until I got my Marantz Reference series integrated and SACD player. I found it muddied up the sound a bit so now I use the standard (really overbuilt) feet that come on the units. They sit directly on thick maple shelves and sound best that way.

I guess it all depends on your units footing, the medium it's sitting on, and your take on it. Time to experiment as you'll get lots of advice (all which works for those advising) but as usual, YMMV.

All the best,

I've had very good experience with Marigo Mystery feet, currently on the F8 extreme -- they are expensive ($1500 per set of 3) but work very well on my ARC 40th pre and Ron offers a 30 day trial and full upgrades to any future versions. You will need a good amount of clear space on the bottom of your pre to use them. In the case of ARC components there's not really enough room between the bottom ventilation plate and the front plate
