NO, NO, NO! Don't mix up two different ideas. Maybe I am at fault for
not explaining this clearly. I am talking about inherent vinyl noise.

No you are talking about the vinyl noise in *your* records on *your* rig.

You
seem to be assuming that *that* noise is indicative of the inherent noise

floor
of the medium. I think you are likely wrong about that. I bet the medium is
capable of better.


I bet it's not capable of anything significantly better.


I bet it is.


Name your wager - I bet $10,000 that a SOTA rig is not more than 6dB
better in this regard than any basic 'entry level hi-fi' vinyl rig.
Say for instance something that you would sneer at - a Rega Planar 3
(or equivalent) with a Shure V-15 cartridge.

This is easily established with *any* vinyl of your choice.

This has nothing to do with any "grundge" recorded on a CD as part of
the program material, nor does it have anything to do with badly
recorded CDs that might sound harsh, or are otherwise flawed.

Sure it does, Unless you are using the quitest records available you are
measuring more than just the inherent noise floor of vinyl. Same goes for

your
rig.


The inherent noise of vinyl is the inherent surface noise on any
record you happen to have - so long as it's been properly cleaned.


And it varies from record to record substantially. So unless Michael is using
the quitest records available he is not reporting the limits of the medium but
the limits of *his* records.


Oh, so now you're saying it's the *record* that matters?

To suggest that only say 1960s JVC vinyl can be used, is risible.

I never suggested any such thing. To suggest that any old record represents the
limits of the medium is plainly false though.


Funny, I thought that was *exactly* what you were suggesting above.
Please get back to me when you have a *consistent* argument to offer.

However, the benchmark doesn't vary by more than a few dB from say a
Planar 3 to a Rockport Sirius III.


Really? How do you know this? Besides we ought to talk about the difference
between Michael's rig and something like the Rockport.


I'm an engineer, and I've listened to the Sirius.

No vinyl ever made had *inherent*
surface noise more than 55-60dB below the 1cm/sec reference level.


Please cite your evidence and then lets talk about how that relates to
Michael's measurements.


Measure any vinyl you have on any rig you can find, then get back to
me. I won't be holding my breath.

There
is no comparable digital artifact because, with properly applied digital
techniques, the noise floor drops to essentially zero.

If you want to know what the limitations of the medium are and not just

the
limitations of your stuff I suggest you use a Rockport TT or Forsell that

is
properly isolated or even a fully decked out Walker Procenium Gold.


Yup, I've heard the Rockport Sirius, set up by Andy Payor himself - it
exhibited perfectly audible surface noise, as you'd expect, since it
was playing *vinyl*.


So says you. I have alsow heard substantial surface noise on SOTA rigs with
noisy records. What records were you listening to and did you actually measure
the surface noise?


No measurement necessary, it was clearly audible on records chosen by
Andy to demonstrate the Sirius. Besides, why are you *now* demanding
measurements? Wasn't your point that it's not *audible* on a good rig?

If not you are just offering anecdotal evidence. You know,
the kind of evidence that leads people to claim substantial differences in
cable sound.


Sure, so I'd be happy if *you* could supply any solid evidence in
rebuttal to what is basically common knowledge, and in accordance with
known measurements of surace noise.

I don't care what turntable/arm/cartridge one uses. Lp surface noise
will be audible, especially when monitoring using headphones.

I think you are wrong about that. You *might* be able to here it cranked up
with no music playing but no way will you here the surface noise at normal
levels with any kind of music playing if you are using SOTA equipment with

SOTA
records.


Utter nonsense, surface noise is *always* audible in the quiet
passages of music, regardless of the quality of the equipment - it's
an *inherent* problem of vinyl.


My experience would be that you are simply wrong. Maybe you ought to clean your
records or adjust your TT. If you are hearing surface noise while music is
playing there is something substandard in the mix.


No, it's an *inherent* flaw in the medium. Maybe you ought to clean or
adjust your prejudices...................
