RE: Thanks for the review ...

From time to time I wonder how much of a difference a linear power supply option would make. I'm thinking the Firestone Audio Supplier PSU would be a good experiment, as it has 24V 500mA (HTA-1 approx 380mA @ 24V). Just not sure if the plug is the correct size, but should be possible to modify if not.
Then again for the price and performance value of the HTA-1, I might as well enjoy as is.
The ERS is not one of those "voodoo" tweaks. Sometimes with GRPS data phones I get that tapping/beeping noise through audio transducers, waving the ERS in between I can clearly hear the difference in blocking some or all of that interference. Inside an audio chassis, my goal is to minimize internal RF. I could take it further and cover the transistors, etc.
I use ERS on chip-based designs, I've never had to use ERS on point-to-point wired components. When people use "too much ERS" and cause the sound to get "dull", I really think they had been compensating for the "excitement" in the sound caused by EMI, and now they are hearing the real sound of the gear they have chosen.
