30 years on...

I have nerdily put my stylus on the run-in groove and tapped the plinth of the LP12, as penance. With the preamp on full volume, a faint "bonk"-style plinth-tap noise was audible through the speakers. Audible acoustic feedback is not really going to occur with an LP12. Mana still has an effect, apparantly, when the hi-fi bits are in a different room from the speakers. I don't find that surprising, but many people do.

 

Bub,

Just for kicks, grab a beer and head over to your hifi. Assuming noone else is around, stand near your Mana array and "bark" at the damn thing like a dog. One short, sharp, loud bark should do it. Back-off ten feet and try it again. Exactly what would you call the weaker replica (echo) of your bark which emanates from the Mana array immediately after you barked?

regards,

dave

 

I'm sure bub's already done that.

 

Well, I always thought Mana owners were barking so I guess here's my proof.

 

Could you then explain the reasoning behind your posts? can you produce the proof that Bub has failed to do despite promising it pages ago?

 

Hi all,

I use Mana stands under everything (although not towers of the stuff), and I use it to tune the dynamic frequency response of my system. I find that the stands do have an effect on the perceived frequency (although I doubt you could measure it). However, this effect is not fixed, in that the stand has a sonic signature. The equipment's position on the stand alters the perceived response. It is as if resonanses are being shifted as you slide the equipment backwards and forwards, and this is audible through the loudspeakers.

I have not done this with a TT, but I have a four box CD player, and each box has to be in the right position to get the sound right.

I know this sounds mad, but I am happy to demonstrate it to anyone who is interested.

The moon is made of cheese.

Dcathro - yes that's insane.

 

So... if stands etc alters the tonal balance then why not just put the HiFi through a graphic EQ?

 

No doubt it is in your world. And the trees are purple and the the sun has a smiley face. Still nothing to back up your story over here in the real world?

 

Fox. Some of us have done this. The trouble is there are 1 million and one combinations to try if you want to deviate from strict neutrality. But I have tried this with both mains filtering/cables and racks.

 

You are the one with the wacko theory, laddie-boy.

 

That has been supported by Markus, DCathro, Penance, Michael etc etc.

Your supposition still stands alone in this world, awaiting the proof you promised to provide.

 

I'm looking for reasoning that shows how stand can affect tonal balance, that justifies the addition of random noise as equating a change in tonal balance, that makes any attempt to rationally quantify the effects being claimed. For any reasoning at all in fact.

Maybe the turntable that doesn't howl round is actually rare? And usually a 30 year old design?

Paul, how else do you explain the subjective tonal shifts referred to by a number of Mana users on this forum?

 

If the tonal balance of my equipment wasn't right for me I'd first look to see if there is equipment that is right for me first not attempt to alter it with stands and cables ... Now it it were for a definite/consistent tonal balance problem. I'd trim the-EQ on the ATC's active crossover. No big deal.

The concept of 'neutrality' dies when speakers interact with the room anyway.

 

Hey Bub,

I know !!! But I can easily demonstrate it.

 

Change the record, you are beginning to become rather tedious.

I have had plenty of people listen to my gear. I am not aware of any tonal shift issues, and neither are any of my visitors.

Markus Sauer is seriously ill at the moment, but when he recovers, he will instruct you in the ways of righteousness.

In the meantime, whilst we await his recovery, I would suggest a hearing test.

 

No Mana users on this forum report any tonal shiftiness.

 

Come on, now! You are a one.

 

Because a graphic equaliser would destroy my system!
