Removal of plug/wall outlet - hard connection ?

Stehno, I know what you're saying. It's just that I interpreted the statement about "gaining another octave" as per the English language (ie 12 semitomes below the original note).
I've been a bassist for 20 years and my wife has a B.Mus Degree, so I get a little tired of a small number of A'goner's who use confused terminology when glowingly describing system sound or improvements.
If we just describe what we hear (for example, "bass notes gained more definition" or "lower frequencies gained strength and prominence") then everyone will be able to imagine what the writer is describing.

"bass notes have gained another octave"

I agree that removing physical connections for hardwired/soldered ones can improve things, but at least keep your stated improvements factual.
Bass notes can't gain another octave unless they're played another octave down originally, or by slowing the audio source down a full octave. Get a music dictionary.

I should also be able to spell "semitones"! Lucky I'm a better bass player than I am typist...

Terryakhan, please don't think I was trying to be insulting, as I wasn't. It's just that our descriptions of the sound of our systems (or any changes) are the only way for us to learn from each other; we obviously can't hear each other's systems.
That's why I'm a bit touchy when it comes to terminology on these threads, as terms are sometimes used which confuse rather than clarify.
Just don't get electrocuted!
