Playing it tonight and I swear it's still getting better!
That will be the burn in Martin..:eyebrows:
Indeed, Paul only hinted at how much those min-regs would need.
Hi Martin,
Just to let you that I tried your earth wire idea, and you're not deaf - it is better! :)
In my set-up, however, it's not really about reducing hum (apart from the tiny bit I had, as described, lifting the tonearm on and off its rest, which has now gone), but eliminating an underlying 'hash' which superimposes itself on the music, and that one doesn't know is there, until running an earth wire from the PCB to the earth post on the preamp/phono stage, as you outlined.
Doing this results in substantially lowering the noisefloor, which is especially noticeable when listening through headphones, where any playback noise is immediately obvious. What adding the earth wire does is create 'blacker silences' between tracks, and when music is playing, vocals are projected more clearly, due to said reduced noise, giving them more presence and realism. Detail retrieval on all material is also notably increased.
The positive benefits of this little tweak make it very worthwhile doing, and I would thoroughly recommend it to all Techy users, not just those with ebony armboards - nice one, Martin! :cool:
Marco.
Nice one, Marco. Good earthing affects sound quality in many different ways.
However, the second earth wire trick will not work with metal arrmboards - you will get an earth loop and more hum! It's only because ebony is an insulator that a separate earth path for arm and turntable is required.
Yup, hadn't thought of that, although perhaps it might depend on the earthing arrangement of the partnering PSU, preamp/phono stage and system?
If not, well it's now even more reason to get an ebony armboard! :)
Marco.
Paul,
Do the prices you gave me a little time back for the Internal regs still stand, and does this include all three stages?
Charles,
The prices still stand, as they are my normal price for each module. Do not forget to allow yourself the AoS member discount of 10%. This applies to all items I offer for the SL1200/SL1210 upgrades.
The lead time for the modules and cables is approx 36 working days at present as I am running behind schedule after work schedule delays caused by December’s bad weather damage to the local grid and the kind person who gave me their Flue-like virus in the New Year. I am hoping to reduce this lead time down to the more normal level of around 25 working days over the next month.
Thanks Paul,
Will be in contact very soon.
BTW, any news on my SR7?
Martin,
I have been thinking of upgrading my wiring from DIY Hynes SR5 PSU to the turntable. What gauge wiring are you using in your setup. I was thinking 16ga would be sufficient but not sure.
I have decided to use an XLR connector on the PSU end, I was wondering if using a shielded signal cable like the mogami quad mic cable would be appropriate for the powersupply cable? I see you use a loose braid unshielded.
I wonder if someone can elucidate me on the pros and cons of such an approach for the technics off-board PSU DC supply cable.
Cheers,
Pete
