Just received the new Allnic 1200 valve phono stage , I believe it uses an CR eq circuit, it is going to retail for £1400, and it sounds absolutely superb, if anyone is looking for a new phono ,I am more than happy to lend this one for evaluation, justleave a mesage here or through my site, www.puriteaudio.co.uk thanks Keith.

I'm offended and sulking because you said I was "out to lunch"

and Ash wants to come and post again but Marco's too chicken to let him.

Does anyone else want Ash to come back ? He's got two new products to tell us about.

JC,

Give it a rest. Ashley's not coming back - I've sent you an email on the matter. It's got nothing to do with me being "chicken" either. And incidentally, Rob's opinion most certainly does count - he's an administrator of this forum as well as a personal friend of mine!

And I'm still waiting for you to answer the questions I asked you on the Sony thread, and why you have a dislike of "japcrap", so get to it please, as this one won't be going away...

So,, .. he's disqualified on two counts instead of only one then.

administrators are the servants of the forum not it's master.

It's a bit like Shareholders, Directors, and Executives. The Shareholders empower the directors as a board, and the directors employ executives to carry out the daily work. It doesn't mean the execs have any valid opinions or authority of their own.

The sony thread appears to have gone off the radar and sunk without trace. It seems a bit ot to resurrect it on Keith's thread.

Meanwhile back on topic, Keith, can't you do a proper phono stage ? RIAA eq distorts most of my records too badly to listen to with enjoyment ?

JC, the matter is not up for debate. Rob (and Steve) has got just as much authority here as I have. It doesn't make his (or Steve's) hi-fi opinions necessarily any more valid than someone else's, but in terms of running the forum and deciding who posts here or not, what he (and Steve) says goes as far as you're concerned.

I'm not asking you to resurrect it here, I'm asking you to click on the original thread, quote my post #26 and reply to the questions asked. Now please attend to it at your earliest convenience. I won't ask you again...

Nonsense. The admin/mod team run the forum, they are not run by it.


It doesn't mean the execs have any valid opinions or authority of their own.

Clearly you've never worked in any sort of business. The very term 'Executive' is derived from the word 'execute' - i.e. to execute the business. In simple terms to 'run' the business. Now if someone running the business has no valid opinion or authority to alter things for the better, then what use are they? Look up the term 'Non-Executive Director' and you'll perhaps understand the difference. Ash is not coming back regardless of what idiocy you type, full stop.

JC; if you continue down this path in any regard whatsoever you will be removed, I'm sure I'm not the only one tired of the same old violin music.

[insanity moment] I think I'll let Ashley back in, actually.[/insanity moment]

JC,

There really is no point in arguing with an admin of three panel in agreement backed up by a majority of our members. I think we should rname you J(K)C - John (King) Canute!

I'm considering the facility that Naim sometimes use on their forum. I's called placing a member under 'moderation.' This basically means that a member under such a restriction has to have his posts approved by admin before they appear in public view. I see this as a useful tool in encouraging you to answer specific questions. Once you begin to employ evasive tactics as probably taught to you by Ashley we put a block on your posting rights until you come up with the requisite answers!

It's just a thought.

Keith, those Allnic valve amps do look gorgeous.

Hmmmm, I don't like phono stages with RIAA eq.

I have been thinking on this, what equipment do you use to do this, ignoring debate as to how the dynamic range of LP compairs with CD and even assuming that maybe 65dB is available from LP, and you need another 40dB for the RIAA, that means (by my understanding) to get anywhere like the result of using a normal RIAA preamp, you need to be getting something like 105dB on the input of the computer (which I assume you are using). But to get near that in the real world you will need to adjust your levels closely, and every dB less gain you have will be another dB you have lost in S/N ratio.

JC is 'in hand', so don't worry. He doesn't need to be placed 'on moderation'...yet. Good idea to create the facility, though, which Rob has now done :)

Nick,

As far as I understand, JC plays 78s exclusively, which he transfers as digital files in some sort of bizarre recording process. I don't think 78s require RIAA eq.

Ok, fair enough. It would make the requiremenst simpiler. I still think you will need some form of equilisation if you use a velocity sensitive pickup though. But that probably reduces the S/N needed to about 70dB so you could do that digitally without too many problems.

More than half of the records ever made don't use riaa eq, but don't say so on the label.

your thoughts and calculations are correct, the method I use is to apply 50% of the eq in the analogue phono stage with adjustable eq, before the ADC, and then to pick up the rest or zero it back down to nil, in the digital domain. This has the effect of moving the eq control from the analogue to the digital domain where it's much more accurate.

An alternative which is sometimes preferred is to simply use 24bit instead of 16bit. There is then plenty of resolution for any manipulations. This is perfect for live recordings, or digitizing records, but it means you have to stay in the 24 bit domain forever, as down-sampling to 16bit can affect the quality. Also if you start with a cd, you have to up-sample it to 24bit, which is a somewhat artificial process, and cannot create any more sonic detail than there was in the original file, i.e. the resolution is actually no better.

I agree with JC, 24bit is a superior word length and the higher sample rates give more headroom in terms of frequency response. Although whilst the actual resolution is no better when upsampling from 16bit to 24bit, I will say that there is a difference in sound - whether it's better is entirely subjective of course.

Linn Records have used the 24 bit method and gone back to their original masters and released them as downloads. You therefore need to stay in the stay in the digi-domain and therefore you can only play them with a computer but IMO they will significantly out-perform vinyl or cd.

Reference Recordings have even higher resolution masters available and have introduced their own format called HRx.

I know a couple of dealers who are impressed enough by these techniques to want my help to set up dem kit to show off their amps and speakers. They think the sound quality is a definite step up.

Ok Keith, tell us more.

This might amuse you but in fact the specs are almost identical to the imminent new AVI dac, I have heard the prototype and it was stunningly good as well. :)

Don't forget AVI made a world beating cdp long before people like Naim, and are usually well ahead of the herd on quality and technology.

JC Hi I am only interested in the best sound ,I am more than happy to give the AVI DAC a twirl, the Stahl- Tek is really good though ,perhaps its the fourcalass A amps on the output or their own dsp, whatever it has the greatest resolution that I have yet heard ,tremendous dynamics and a very vinyl like presence and weight, I will compare it to the MSB later, regards Keith.

You need to be a bit carefull there, as there is nothing "simple" about actually getting anywhere near 24bits when recording a analog signal.

Thats what I was getting at when I questioned not using a phono stage, you would need at least 105dB resolution, and that starts to become hard to manage in real life.
