I was reading your post with interest until.... I stumbled to the following:

---snip----
"This has proven that the metal casework that ARc use and others is a bad design from a sound perspective, Would you make a piano from metal - NO.
Would you make a speaker from metal - No, Then why a pre amp?"
---snip----

Comparing the material of a piano, a speaker and a preamplifier is obviously a simplistic/misleading comparison.

A piano doesn't process any electrical signals but it is a mechanical device. The shape and material used is precisely what gives musical instruments their characteristic sound.

The fight with speaker enclosures is the the exact opposite of the effect the material has on a piano. We want the speaker cabinet to have no "sound of its own" (that's why people go nuts with bracing , absorbing materials, spikes, shapes, sandbags etc etc etc etc) including building speakers from cement or stone.

Now...I don't dispute that you heard a difference in the sound.
I doubt it is because of the material of the enclosure.

A rusted/oxidized metal cabinet with loose fitting screws "can" cause problems in "RFI rich" areas, where the rust/oxidation or otherwise bad contact of the cover to the main chassis can act as a capacitor or diode and cause all sorts of interesting events.

Any chance of posting pictures of the discarded metal cabinet?

PS: I'll keep the flame suit on just in case... :)
