Very interesting bluster Richard.

I'm listening to the R3 proms as I type this on an Accuphase tuner encased in a steel case. I've just removed it - absolutely no difference, nothing. It is currently playing through a Cyrus 2 amp (not the usual amp) and that also sounds the same clothed or unclothed.

I've worked on and repaired many amps over the years which means testing and listening with the cover removed. Never any audible differences apart from the odd bit of RF pickup.

I don't doubt your ability to build good amps but there is no need to dress up your products with this nonesense. By your own admission you use simple circuits and you execute them well enough. But believing that changing or removing screws from a case will improve the sound of your products puts you into the same catagory as the magicians who constantly invent the perfect cable year after afer year.

Doesn't wash with me Richard.

BTW please stop refering to your opinions as 'facts' - they are not.

I think you need to look a little closer to home there Richard.
