Good thread to start - especially for DHT PRE owners (DHT in the linestage = microphonics).
So far, I haven't used any isolation products with LIO DHT PRE. I'm sure they can only help and I'll be looking
into a few and will eventually report my findings. I want to try Herbies Tenderfoot in place of the stock
LIO feet at some point, and even their tube dampers for DHTs. And there are certainly others...
I will say this - microphonics shouldn't be a problem * while listening *. Of course if you are tapping on your shelf, your
LIO, and (worst case) the tubes - and have the volume turned up, you WILL hear the microphonics in the system and this
is NORMAL.
