A very interesting review and a very interesting turntable and arm. You say that with the heavy platter the spped stability "betters 0.3%". Now I wonder by how much? 0.3% is Broadcast Standard and with my belt drive Nottingham Analogue controlled by a Pro-ject Speed Box I get 0.15%. (Measured with my KAB spped strobe, which I assume is accurate) Does the Salvation Deck better that?

Hi Julian,

Given that the philosophy behind the power supply is to not hold the motor in a vice-like grip if you worry about speed drift needing to be super tight then it maybe better for you to use a deck with some form of feedback mechanism. I've heard the effect of doing this with the very direct rim-drive system of Salvation, there's no question that I prefer no feedback. Given the lack of feedback control who knows you might see 0.1% on occasion - I really can't say - but there can be no guarantees. Better than 0.3% seems typical. As it happens I can't aurally detect any speed drift with the acrylic platter with it's better than 0.6% accuracy. I think any speed drift occurs over a longish period and is benign. Can you detect the difference between 0.3% and 0.6%? Probably some people can but most can't.

I am sure I couldn't tell the difference, but if that is the case why is it important? I just (psychologically?) like the fact that mine is so tight. Adding the Speed box & its getting the speed so tight as well as claeaning up the mains signal have significantly improved the sound IMHO. By the way I am a bit lost as to what a deck with feedback mechanism is - can you explain?

What I like about the Notts Analogue is that it is so simple & the Salvation seems to be so too.

Put as simply as possible you'd have a circuit that monitors the rotational speed of the platter, if it happens to slow slightly the circuit would increase voltage to the motor & thus correct the rotational speed as it'd spin faster...

If it span too fast then it'd cut voltage to the motor slightly thus slowing it down & keeping the speed as constant as possible.

If you like it'd be similar to how quartz lock direct drive TTs work but without the direct drive.

This is perhaps an area for us to listen for when we compare T/Ts.

One thing the Techie is utterly superb at is maintaining totally accurate speed stability, and my ears are quite sensitive to any drift which results in adversely affecting the accuracy of the pitch (and timing) of notes

It's one of the reasons why I now find it difficult listening to belt-drive T/Ts, out with of the high-mass string-drive variety!

Do you have any solo piano recordings? Those are great for sussing out that sort of thing. If not, I can bring some with me

Marco.

[Tea24]

By the way Clive, do you happen to know the footprint of the deck with arm fitted? Just for interest's sake. Couldn't find this info on the website.

Hi Marco,

'scuse the short reply, I'm working from my phone.....the sound is absolutely fine with piano. Any speed drift takes place over a much longer period than a series of notes. The 9kg platter in particular is very, very steady. Any drifting is I believe due to temp changes on the bearing so we're talking drift over long, not short timescales.

Hi Julian,

I'll get the dimensions for you though I'm not home currently, I'll need to get the TT measured.
