Re: Cryo EL84s
I expect that a lot of the fretting over minutiae could be explained by psychologists under the heading of "perfectionism". My father used to sit on aviation accident enquiries where details of the precise alloying of bolts and adherence to heat-treatment regimes really could affect whether people lived or died. Hi-fi is a very different matter and maintaining perspective is important in any field of life, to do otherwise is to risk the exponentiating water-slide of madness. I have read in hi-fi magazines how all sorts of things can affect sound quality as well as cryo-treatment of valves, including the precise colours of cables, sorry interconnects. I'm prepared to accept that different dyes may marginally affect things like dielectric constant and loss- but can it make any significant difference in a competently-designed system?
It's wise to keep in mind phrases such as "vanishingly small", "negligible" and "insignificant" where audio homeopathy is concerned- and just enjoy the rest of life, it's trickling away from all of us |

Re: Cryo EL84s
Um, I don't think that's 1.6 E-19 electrons to make up a Coulomb, I think that's the other way round, but what's a factor of 10^38 between friends?

Re: Cryo EL84s
Precisely. If the kit is properly designed and built and the contacts are clean, nearly all the differences vanish like smoke and those that remain are not of the variety which defies Ohm's law.

Re: Cryo EL84s
Oops, sorry, Lucien.
And there's all that wire in the speaker voice coils! Ripe for cryo-treatment. David

Re: Cryo EL84s
Continuing the cryogenic theme, there may be a good market for superconducting speaker cables - boron nitride or similar - with circulated liquid helium. It's all feasible - at a price! Probably need to install the helium fridge in the next room to avoid the background noise.
Perhaps one could then launch some upmarket speakers with a difficult impedance curve which depended on superconducting cables to maintain a flat response. I can see the business plan coming together before my very eyes! Martin

Re: Cryo EL84s
Despite repeated requests this thread has drifted inexorably towards audiophool silliness.
Closed.
