Copper Sleeve over IEC

I was able to rearrange AC ends on back of the Hydra adding sleeves over the AC ends of the transport, dac and preamp.

If I notice any decrease what so ever, I'll remove the preamp AC sleeve first, per above comment(s)

First few notes upon fire-up and wow again.

More fully developed harmonics and smoothness, like another component upgrade.

AC wreaks an evil havoc on sound, controlling it is the key, but not always an easy task.

I would be curious however if a couple of the shields are just simply NOT having any negative effect, but also not doing anything positive but lame ducks, like the ones possibly on the preamp.. So if you get a chance let us know.. But again it will really depend on the equipment too I am sure, tube, solid state, overall design and power supply in the component can make this tweak better on some and not so good on others who knows?

Undertow,

I gathered that conclusion among other things as well as tweaks, eg. P/C's, tube types, interconnects, speaker cables etc.

Power supply is a very key matter, ask a guy like Paul or Brian at TRL,
I had a long phone conversation with them.

I'll listen for a lame duck tonight, when everything's quieter and settled in !

About a year ago on another thread, I told of removing the ferrous cover on my ac mains box. That made for a nice improvement and heard by others in my listening room as my system was being played. Tom
