I have assembled a pair of approximately 900va transformers to function as a line isolation transformer. These are placed inside a steel cabinet and are fused at 8A, using a circuit breaker, and definitely improved the noise floor of the digital player/DAC, and a/b amplifier setup.
What I am now wondering, is if there would be any advantages to having the differential mode X capacitors between the two secondaries, as opposed to have them after the dual transformer configuration, as they now are?

IMO if the noise floor improved and the bass is better by using cascaded isolation transformers, there
is some faulty design in the mix. I need to see double blind testing on this. By all means add the
capacitors into the mix but I still want the ABX tests

Thanks for the reply G2.
Well everything subjectively improved, I didn’t intend to describe the bass impression with bad spelling either, and have edited that.
As for an A/B/X trial, it’s going to be a very long wait for that I’m afraid.
This is a system that I listen to daily, and have for over a couple years now, so I don’t need any convincing myself, and since no one else listens to it...
I’m really looking for some compelling arguments either for, or against the placement of differential mode capacitors within the filter arrangement.
If I had a serious analyzer or something, that would be fun to play with for sure.

You may have found what I call the "dripping faucet syndrome". I have observed this in myself as well
as others. Minor little problem that on careful analysis HAD to have been there for a long time but you
just noticed it now. The trick is learning to ignore it again. The paradox is, it is NOT in your head AND
it IS in your head at the same time.
PRR has the right idea. Put in switchable caps and check it out. It may turn out to be very interesting.
Or not.
