All you have to do is find an LP12 fitted with an arm other than the Aro (Ittok, Ekos, Basik etc).

While fiddling with Marco's deck and Ortofon SUT (step-up transformer) on Saturday, I happened to touch one of the silver transformer housings and got hum. We realised that the SUT was not being earthed from the interconnect screens but was independently earthed via its earth wire. Connecting that to my phono amp's earth terminal made a substantial improvement to dynamics and lowering of the noise floor.
So tonight, while reconnecting my system, I earthed my Choir Audio SUT in the same way. I've just discovered an improvement in focus and a further lowering of noise floor!
The lesson is: even if you have no hum, your earthing arrangements may not be optimal. I star earth my turntable, arm and now SUT separately to the phono amp's earth terminal, which then goes back to mains earth. You might all want to check your earthing arrangements :)
Yes, I do (not my SUT because I don't use one, but my deck, arm and phonostage. I would agree that even quite subtle differences to ones earthing arrangements can have quite a profound effect.
Nice one on the SUT earthing, Martin. It was amazing the difference it make doing it to my SUT, on Saturday, so I'm glad that you got a similar result!
Yannis has been in touch, and the SPD-4 will be shipped on Wednesday, which means it should be with me for the end of next week... Can you keep your suspenders on until then? :DQuote:
So hurry up and tell me what the SPD-4 is like, Marco, as my wallet is ready to drop money on a 'special' 423.5 :)
Marco.
I like the idea of star earthing and have such an arrangement in my own system.
Attention to earthing can make an enormous difference. Dare I say it, but it can make as much of a difference as changing cables. :sofa:
Too right! :)
Marco.
Phew! - You let me off lightly there Marco. I was expecting you to berate me over my views on interconnects.
I am in the processs of assembling a tone arm cable for my Breuer arm, which has been in retirement for far too long, but whose cable was never of the highest quality (unlike the arm itself).
When I'm done, I'll post some photos and details.
Looking forward to it. Tabatha has asked if you could run the final design past her, as she wants to be the first to scrutinise your new 'snake' ;)
Marco.
I wonder how my Graham IC70 would compare to this cable :scratch:
Did you compare the LP12 with the Technics directly ?Quote:
