...Seal the screw and you may not be able to tighten the connection again.

 

 

explain this

 

do you know what purple loctite is?

[Ralf11]

better would be to use a purpose made heat sink - mine have thick copper "jaws" but operate like spring loaded tweezers

[Ralf11]

Exactly.  And the poster said that his terminals are coming loose, sandy.

 

 

the other issue is the use of Tweek, and Frank's belief that it is not adequate...

 

maybe he can detail his listening methodology as to whether a statistical number of trials, and whether he used blind listening

 

I agree Cornan.  For a consumer, why is less important that the result.  But one must ensure the result is actually SQ and not just an expectation that is confirmed for psychological reasons.

[Ralf11]

We need to lock Sandy and Frank in the same room for a few weeks.

[Ralf11]

I did not give any bad advice, Sandman.

 

Let's see how many items of audio gear.... maybe a half dozen - I usually focus my efforts on constructing scientific gear.  Things that absolutely have GOT to work.

 

Purple Loctite will be fine and will solve his problem - of course, so would other things, like ripping it all apart again... however, I would not use banana plugs as your close friend half-pint suggested.

 

He can probably get away with soldering the tips tho I would not do it.

 

Airtight connections are wise - he can probably get away w/o that tho.

 

And finally... Ghent

 

!!

[Ralf11]

you guys are a treasure of wrong ideas - thx for the laugh about science

[Ralf11]

Back to the cable and several caps laid out in a series along it, but which are electrically in parallel...

 

You mentioned it was hard to build:

 

I think a jig could be made to hold everything in position and make soldering easy.  That jig could then be give (or sold if you're into markets) to the next guy.

 

Or those interested could perhaps get a specialty pcb run made ... the traces could take the place of most of  the wire, and the caps could just drop in.

It is entertaining, if nothing else.

 

just wait until we get to the use of Cu vs. Ni based anti-sieze compounds

[Ralf11]

He's right about the possible damage form stray or loose strands.  And it is hard to get them all.

 

A slight bit of tinning won't cause nearly as much damage (if any).

 

If you are tinning-phobic then use spring clips to secure the tinned ends (!!)

[Ralf11]

Back to point to point wire [wrapped] tube amps!

Ah but do you get better SQ with quad or hex crimp? or audiophile decacrimp? Pure silver boots?

 

Boots of Spanish Leather

[Ralf11]

Don't forget, when you reconnect something you are often breaking a corrosion barrier.

 

That can explain a lot of the changes in SQ from switching cables, or clipping off tinned ends, etc. etc.

 

 

I like to flood my stereo equipment with Argon to 'solve' the corrosion problem.

 

 

Also, in space no one can hear your stereo scream!

(just for you marce)

This is AC, not DC. How can this help?

 

was that a joke?

[Ralf11]

lotta loose screws on this thread

[Ralf11]

I do need to go outside and wash the sports car.

 

I think I'll even turn on the aged Pioneer SuperTuner radio in it...

[Ralf11]

Ghent ??

[Ralf11]

what are the distortion artifacts that digital is always struggling to get under control??

[Ralf11]

EM noise in a power supply can affect any analog component, and all DACs have an analog section

 

I've never seen anything convincing that noise in a purely digital component will affect SQ - assuming it is adequately isolated from all analog stages (and that could include parasitic leak via transformers).

 

Ultimately, you may need to conduct test to compare 2 items or treatments and see if you can hear a difference on your most demanding source material.

In that case I would suggest that you spend more time reading the numerous threads by multiple members in other areas of the forum instead of trying to create a Guinness  Book of Records entry for the most number of posts in the shortest possible time frame in a forum.

 

 

you have me cornfused with your trolling friend - one of your Aussie mafia

The killer is that word, "adequately" - how do you do know when there is enough, "adequate"? Answer: that when you add in even more isolation, that such makes no audible difference ...

 

 

If there is not enough EM noise to flip bits on the digital side you are fine (and that is quite a bit of noise).

 

Your point really comes into play where Digital meets Analog or in Analog components.  I certainly agree the DAC needs careful noise isolation.

 

If anybody has either:

[1] engineering explanations, i.e. mechanistic explanations, 

or [2] valid listening tests (say by noise injection)

 

that EM noise in purely digital components is a problem (with the caveats above) then set them forth.

Sandy,  Pls re-read; you seem to have missed item #2.

Yes, while we are talking about the purely digital areas, and we have established that there is zero spillover into any analogue areas, by any path whatsoever, to a degree that has audible impact on SQ - then there should no problem.

 

 

ok, so we isolate, re-clock, use Big Buffers (the subject of a song by Sir Mix-A-Lot)*

 

and then we need to be very careful with the DAC and with the amplification chain.

 

That will accurately reproduce all the crummy masterings we have (and the few great ones too)...

 

...until we get to the speakers & room.

 

Those are the problems as I see it.

 

 

* which are the things the iso-regen focuses on, does it not?

[Ralf11]

I advocate batteries too, BTW

[Ralf11]

If the OP hasn't specified, then it is not so limited.  Now did you read item #2?  

 

here is a helpful hint: item #2 is a Subjective item.

 

I feel sorry for the ostrich who posted above, and hopes he finds his snowflakes.
