Just noting the responses you've added from users, especially the second one: "added musicality with older cds", "intimate live performance", "listening at low volume levels" are all spot-on markers - you're on a roll with this approach!

Thanks Frank - that's good background detail of the weaknesses inherent in feedback circuitry. The transient response shortcomings are a possible explanation for why local feedback loops are considered more benign than global feedback loops - assuming the local feedback loop having better transient...

Watching what happens in circuits that rely on NFB to correct poor HF behaviour, in something like LTspice, shows why this is the case, at least in some instances. The output stage starts to distort, the FB loop then drives the input and intermediate gain stages hard, very hard, trying to correct th...

John, "low level detail" covers a lot of ground - timing issues would cause a type of distortion which would cloud the ability of the ear/brain to "see" that the content of the music all made sense - this is low level in the sense that it's hard to measure precisely what's going ...

Thanks Damien for an interesting story - I didn't know about DXing - very interesting Glad you are liking the ISO-HUB - as you say it's not about revealing new details in the sound, what I find the ISO-HUB does is make what's there sound more real, deeper soundstage, more air, etc. - all the usual ...

Very informative thread, Richard - good to see the detail laid out like this!
