Your combination:AC isolation/condition devices

And power cords. My experimentaion reveals that combining complementary (synergistic) products offers dramatic
refinement-particularly for CD enjoyment and preamps.
One example is the use of an Equitech 2Q balanced transformer with an MIT Z Stablilizer.
I think this is an area that merits our united attention and will effect significant enhancements, far surpassing the use of any one unit or brand. Discussion of the how & why technical factors, i.e. frequency ranges affected, method of the device, could be informative & very interesting if tech savvy members contribute. Hope so.

I use an isolation Transformer, then passive parallel filters, then a 193L choke wired into the IEC end of my power cord, to my CDP and my Dac. Great results!!

Thanks Benie, what does the choke do?

The choke is another filter, helps very nicely with clarity. Do a search on AA for 193L Hammond Choke.

I've implemented the following chain of PC's for my DAC:

- Jon Risch power conditioner (choke and cap filtering and varistors for surge supression), into
- Jon Risch digital isolation transformer (configured as a step down transformer w/ a cap filter across secondaries into a step up transformer), into
- Felix power conditioner (transformer and cap filtering)

Hell, after all that it probably would have been easier to just get a regenerator from PS Audio. Anyway, it seems to be effective and I definitely hear improvements using all 3, and a worsening if I pull one of them out of the chain.

Enjoy,
Bob

Sounds thorough. Do you know up to what frequency noise is attenuated?
