The Herbie footers - Isocups and Tenderfeet both did no harm. Cheap enough to experiment with both - he recommends the Isocups for tube eequipment, but Tenderfeet are just as good under tube equipment IMHO. I used JPC AC PCs to good effect with when I had my LA 150 Signature Edition.
Placing footers under Joule LA150 MKii
I'm using a Joule LA150MKii in a second system and wondered what footers others have found satisfactory under the Joule preamp? Stock footers seem quite inadequate and I'm sure upgrades are in order. On the same subject, what power cord have you found works well with this pre? Personal experience is prefered.
