If it's USB surely it has a built in preamp and A-D convertor?

Yes, of course. (I'd forgotten USB) But at about £12 for the cartridge, I
can't imagine it would be even moving magnet.

I dunno the relative manufacturing costs of MM versus ceramic. This
sort of thing has shifted dramatically with CAD machinery.

Oh, so whats now considered a good cartridge?
It used to be (generally) moving coils in the days before things went crazy.

Most cartridges are moving magnet.

IDIOT !

It might be a single-chip solution. No need to mount it in a heavy
DIL package.

Good. It will make the chances of the item coming quicker to market even
better being priced competitively by a number of manufacturers. Come on
down!!!

BTW, not connected to the above statement, but interesting none the
less. It is now possible to search patents through google

Standard wiring, not standard use of that wiring. There's 4 wires in

Dave, you don't have to rush SO fast to knock an idea flying :-)

You're right. At least a two second pause would have been appropriate
for this one.


Yes! A small memory buffer (think two seconds may be a teensy bit long)
built on the device with a DSP declicking algorithm ... ;-)

:-p

I've seen these things advertised and they look very plasticky. Did
actually see an el-cheapo turntable the other day which I'd imagine
would be very similar to the mechanical part of one of these things.
Yay, ruin all your precious irreplaceable vinyl...

If I'm transferring vinyl to a digital format I use a Rega Planar 3,
RB300 tonearm, Ortofon 510 cart, Pro-Ject Phono Box II and Sony RCD-W100
CD recorder. Record to CD-RW, extract to PC, clean up (de-click etc),
burn back to CD-R.

The results are generally pretty good actually, especially if you turn
on SBM (Super Bit Mapping) on the CD recorder.

I'm a little puzzled by the steps you use here, Glenn. Why do you
record first to CD-RW when you could go straight to PC? That would
save a transcription step, which is always good. And of course with a
PC you can choose your sound card, which means that the ADC is a known
and guaranteed high quality item. A CD recorded is a bit of a pig in
a poke, and while it may be good, there is no way you can assure
yourself of that.

I've generally found a few problems with using a PC sound card to
capture stuff like this. Often the audio will glitch if, say, Windows
decides it's going to start swapping stuff (this is on a P4 2.4GHz with
1GB RAM, so no CPU or memory issues). I'm also less than convinced about
the quality of reasonably priced sound cards, to get anything decent you
seem to have to spend quite a lot.

More importantly, and perhaps more practically, I don't have a PC in my
living room (where the hi-fi is located). The onboard sound card on my
old laptop (eMachines M5116) is pretty much appalling (hooked it up to
the hi-fi once and the only thing I can say is TOTAL harmonic
distortion!). The new laptop (Compaq R4000 series) doesn't have a line
input, only a mic input. So it'd be a case of using a USB or Firewire
sound card for capture.

It's far easier just to record stuff to CD-RW and capture that way. The
ADC in the Sony recorder is actually pretty damned good.
