Screw/Casing torque

Posted by: Mike Sae on 29 January 2002

Seeing as the 5 series has a specific torque setting for the screws, does the CDX have similar settings? I'd like to take the lid off mine to take some piccies of its innards. If the screws need a specific NM setting, I'll just leave well enough alone.

I'm taking for granted the fact(?) that 72/140/Hicap screws/bolts don't have any specific torque setting.

I know I'll probably be shouted down, but isn't this getting..a little extreme?

Wouldn't any effect of the screw torque (with the possible exception of just not putting them in) be far outweighed by room effects and other artefacts?

C'mon guys - just do them up quite tight, walk away and listen to some music.

The same applies to how much torque you use on many stands.

QS Reference sounds more open when tightened with just finger and thumb on its rods.

My old Optimum stands came with stern warnings about not overightening the rods supporting the shelves...

I've noticed this phenomenon regarding the QS, Stallion has noticed it also - I'm sure you won't mind me quoting you on this one Marco [smile smilie], and my dealer gave me a similar thumbs-up when I lent him my Mana Spirit level for completely rebuilding his QS Ref. stands in his demo room.

If it works with the stands, then it has to work with the boxes as well, yeah?

Moreover, Rega supply a torque kit for tightening their cartridges on the end of their tonearms, and Music Works' blocks are assembled with particular attention paid to the tightening of the screws therein.

Hi-fi tweaking is a weird game, and an open mind to these matters seems to yield sonic benefits, so it seems senseless to me to dismiss such ideas out of hand because they don't make sense on a superficial level of logic.

Systems can be made or broken on some very tiny pedantic details!

Cheers,

Steve.

Steven -

I can only apologise. Please go on fiddling with your nuts.

I now leave well alone - no more fiddling.

If I need to have something opened, then it goes straight back to the manufacturers, or my dealer who knows...

Cheers,

Steve.

I've just moved the phono boards from my old 82 into the 52 so I can spin some vinyl. I don't know how tight the rubber feet should be. Any suggestions?

Best wishes,

Mick.

AFAIK, tighten 1/8 of a turn with a screwdriver or simply finger tight.

As for the hex bolt, I think it safe to assume 3nm, as per the 5 series.
