NVA amps

I don't use screws so none are loose, they mess up the sound

 

Precisely! So loose they fell out completely!: :MILD:

 

Richard,

Have you ever tried carbon cables as advocated by VDH for internal wiring?
It would take the removal of any metal from the amp one stage further.

 

Didn't one company use fluid in their cables?

Mmm how about a mercury filled pure silver tube? I challange you to try that Zanash!

 

You misunderstand, I like metal, I want metal, I want the most conductive metal possible, especially for cables. BUT only where I want it, everywhere else metal is used even not in circuit is *induced* to create an infuence, in that case I don't want metal. If I want a resistor I will use carbon, but other oxides are better.

I would very much like to try super conductivity for audio work but the costs involved are too great. Even so it is well worth watching the current work going on into super conductivity by the computer guys that doesn't involve ridiculously low temperatures.

Richard

 

Super cool it and you have something very interesting.

Richard

 

And your qualification to judge that is?

I don't know you from Micky Mouse, but I have been called nuts ( all we need now is a reference to bolts) by many more famous people than you.

Interestingly by the end of the 90's a large number of pundits were singing my tunes, so times have changed again have they!

Richard

 

Since electricity doesn't travel like 'normal' when in super-cooled conditions, can/should it be treated in the same way?

 

No need to get an attitude, I said it was in the kindest way possible! I think your theories on getting rid of the screws are nuts (oh dear) but I was only having a giggle a the pun.

Does it matter who is famous?

 

Since when does electricity travel normally - what is normal? Is a plasma ball normal? Is a static charge normal? It is just potential looking for differential to fill!

Richard

 

I just like to judge whether it is an idiot I should listen to or an idiot I should ignore. Anyway I am speaking to everyone at the moment. Perhaps it is time to *bolt* for cover and belt up!

Think! why does a screwdriver magnetise by screwing. What influence is at work? Is it just the screwdiver or is the screw also left with a stored potential. What happens when a piece of metal has a stored polarised potential, be it magnetic or induced voltage, and develops a *friendly* relationships with other nearby conductors.

As King Louie said "I wanna be like you hoo hoo"

Apply similar thinking to stranded twisted cable!

Richard

 

Thats why I put normal in quotes. I was once told electricity travels more like a fluid when in super-cool conditions so I wondered if it could be treated the same way we usually do in a circuit.

 

How about the fact the materials are transported around the world in all different directions. What if the screws vibrate round more in one direction than the other when in transportation? Do people with amplifiers nearer the magnetic poles get worse sound because things are magnetised more?

I'm sorry but to me it seems more likely you are imagining the effects as they would be so small. Still that does not mean you can't make great equipment, just that you probably waste a lot of time doing silly things like not using screws.

I'm not going to bother replying anymore as for one I have not read the entire thread or indeed your full post, but mainly because I just intended to have a giggle at the pun and leave it at that. I have no desire to enter into a heated 'debate' right now, especially given your attitude, which I accept is probably a lot to do with the thread I have not read so I will let it pass.

 

Look,

At the end of the day all this stuff is very interesting to discuss but doesn't change the sound of an amp or cable in the slightest.

Brass screws, copper screws, steel screws - stick the amp together will old chewing gum or toffee - It'll sound the same.

Wacky ideas are often simply a sales tactic to differentiate one perfectly competent amp or cable from another in the market place, when no real difference exists. It has much in common with the way the Linn 'tunemen' would tap there feet, smile and get animated when the 'preferred' turtable was playing, or the characters who scream and shout at the poor punters at hi-fi shows, implying that they are stupid if they cannot hear the superiority of their cable.

Belt up - now there's something to think about. You aren't related to Peter Belt are you Richard?

Anyway, enough of this nonesense, its time for bed.

Night all.

 

I can't see why you guys are having a go, in my very limited experience there is good reason to believe that casework etc. has an influence on the sound. Induced currents,rfi etc. all have an effect. Richard is not the only designer to think that un-needed material is unwanted.......didn't LFD also make amps with uncovered output wires, for the same reasons? I seem to remember that they even went so far as to remove the metal from the volume pot shaft, because they said it had a negative effect on the sound. Tom Evans seemed to prefer plastic/acrylic cases. I am not saying Richard is right and "everyone" else is wrong.......or vice versa, but there is surely more to the sound of an amp (or any other piece of equipment) than can be measured or calculated. Science doesnt have all the answers.
The "perfect" amps with better measurements than Kylie have been around for decades... but plenty of "audiophiles" say that they sound sterile. I'd sooner buy an amp from someone that places more belief in his ears than in his oscilloscope.

 

It is always the same reaction, as soon as there is a new idea, the establishment feels threatened... :NADowner:

I enjoyed very much Richards posts, a bit of fresh air...

 

Hot air more like

 

:bub:

Pardon my French...

 

NVA is not alone in supporting this approach - for example DNM have been using 100% acrylic cases (except for the heatsink on the power amp where the transistors are spaced from it by ceramic blocks) for years.

Electromagnetics also back up the theory - cables will produce an electromagnetic field from them, and metallic objects nearby can pick up the nearfield, the electrons in the metal can start oscillating (like a passive antenna element) and re-radiate back to the cable.

Best,

Andrew

 

Andrew tis very true Mr Moorcrofts designs as this way also.
His dnm reason cable (solid core) was designed to compliment his amps.
