I wuz going through my 'spare kit' with a view to putting a few more
things on ****eBay when I happened across my hitherto neglected AKG P6R
cart with is spherical stylus:

...and I thought 'better give this a ride to see if it's any good - if
not, I'll get rid'! So I rigged it up (by eye only - only saps use
protractors and scales :-) and bunged it on my GL72 'Victoria Sponge'
deck:

Then put on a disc on which I thought might give it a good workout!
******oso mio!!** Furry animals fell out of the trees outside, a car
swerved off the road, the front door fell out and the guy next door put
his house up for sale! :-))

Here's a 'warts 'n' all' snatch/track/snatch which will show you a) how
*not at all bad* this cart is despite its lowly spherical stylus and b)
why vinylistas larf when people bang on about stuff like CD's 'dynamic
range':

First, miked from my TL speakers:

And then recorded direct to hard disk to show what it *should* sound
like I suppose!!

Put your best cans on and wick it up as *large* as you can stand; then
take a grip of summat that bolted to the floor!! (Not for the Quad
Squad!! ;-)

(Tell me he's *not* saying 'Vegetables, Fresh Vegetables'....??)



Mic very close to speaker, yes? And not directly in line with the
tweeter. This the first mic recording of yours where the direct
recording has been brighter than the mic recording. So I'm guessing
you used the IMFs and a pair of cardioids, if not the ribbons.

Dynamic range is good for vinyl at about 50dB, but there's still
better than another 40 to go before you would start seeing a CD
sweating.
