New Paul Hynes SR5 Power Supply

Hi Andrew,

Now that seems like an offer too good to refuse. Let's wait till after Xmas, I need to fine tune the Mike New bearing/stiffning plate/Cu composite platter and SME V before I let the Timestep go. I've only just got the whole thing set up and working so I want to listen to some vinyl before I embark on another batch of upgrades. How does back end of January sound??

Sounds good to me, matey - that's a plan, then! :)

I've been dying to compare the Timestep HE to the SR5, so now's my chance. Full review on their various merits to follow... :cool:

Btw, I've just taken a few new shots of the Techie - this time off of the rack, after fitting the new Oyaide PA-2075 DR tonearm cable to the Jelco:

Looking good Marco, looking good.

Churz, matey... Off for a listen, now! :gig:

Marco.

Just looking at Paul's PSU and being interested in the mains supply for obvious reasons, couldn't help wondering what effect this would have on the performance?

Basically a mains filter/iec inlet. Not suggesting anyone takes Paul's unit apart and fits their own, maybe Paul would like to try one out and offer it as an up-grade if it does the job?

In my case, no need as my SR5 is being fed ultra-pure mains from my PS Audio Powerplant Premier regenerator.

Is that the one that uses USA power plugs mate?

It will be interesting to know what you think about it in comparison with the Neglex cable. I was very surprised at how much better Audio Origami's tonearm cable was over the Neglex, which looks nice but is a bit average sounding. Methinks you are about to remove a musical bottleneck!

I'd definately say that it'd be much cleaner & lower distortion than via a simple mains filter, that's for sure ;) The Premier reduces distortion by a factor of 10 from what i have read which is significant, but i wouldn't call it ultra-pure by any stretch of the imagination :cool:

Still, 0.25% is better than 2.5% & a very worthwhile improvement :eyebrows:

Having said that i wouldn't dismiss a mains filter as most of the distortion on the output of the Premier is likely to be high order & high frequency ;) It is effectively only an amplifier at the end of the day & feedback reduces with increased frequency meaning distortion increases :rolleyes: These kind of filters are not effective at low frequency but increase in effectiveness as frequency increases....

No, I have a proper UK spec model with IEC (Euro) input and five UK 13A sockets, one for each isolation zone.

It depends on what you're comparing it with. A filter won't be able to reconstruct the straight-sided sinewave distortion that occurs when thousands of Sun readers put the kettle on before Eastenders, but the PPP can and does. Also, it's not just about purity of sinewave but broad spectrum noise filtering before the amplifier stage, thus preserving low output impedance. And as I think we've discussed before, it's a rather clever tracking amplifier that sits 'on top' of the mains waveform and applies correction, unlike its enormously heat dissipating predecessors. So no heat, little noise and no fans whirring.

I take what you say - distortion is reduced not eliminated - but the proof is in the listening and I've yet to hear a system that is not improved with a PPP.
