Because the supposition is that Mana alters the tonal balance of a system. Without knowing what it should be sans Mana, how can you objectively prove one way or another? Surely that's obvious!
 
Simple. On Mana your test tone CD will give you your in room response 20hz to 20khz. It will not be totally flat. Are those lumps and dips down to soley the room, or is one of them down to the Mana?
 
If your theory is correct, there ought to be wild variations in level. There weren't any.

It's a bit sad when a beautiful theory is ruined by an ugly fact. You could have claimed a Nobel Prize. Just imagine...
 
Variations of 1db in the midrange can have a noticable effect on the system's presentation. These things are somewhat more complex than you seem to appreciate. I don't have a theory.
 
Amusing, but just yet another diversion when confronted with facts.

Can you tell me what the frequency response is in your room with and without Mana, 20hz to 20khz, to within 1db accuracy?

I've an open question to all that attended: Why have visitors to Bub's recent nerdathon (or anyone whom has visited) not been moved to go the Mana route?

Fox, your email seems to have packed up. Have you sent me a cheque yet? Sorry I dissed your dogs.

I think I need an expert like you to measure properly. Come & do it.

The test-tone CD. This will demonstrate any tonal shift.

Bub,

I don't believe it will. The perceived effects I get cannot be detected on a tone sweep, but are noticeable with dynamic music.

Please note by the way, that on my part, this is not a complaint about Mana stands. The benefits I get from them are profound, and their ability to tune a system via perceived tonal shifts is extremely useful.


Also, I don't believe that the stand's are changing the freq response of the equipment, but that the vibrational resonances within the equipment are audible, and that the stands can be used to drain these resonances. The perceived tonal shifts are, I believe, caused by the changing summation of resonances.

Sorry about the terrible attempt to discribe this

David

I'm not an expert, just a listener like you.

But do you now accept that Mana results in a perceived shift in tonal balance given the overwhelming testimony to that effect?
