You've run some pretty fancy MC's, but the _______ MM cartridge really impressed me

@mijostyn - Might that have been the MMC 20CL?

MMC1 or MM20CL. I destroyed the OEM cantilever on my MMC1 because of the stupid built in stylus guard. Had it replaced by SS but their sapphire cantilever is solid as opposed to a hollow tube in the original and looks less delicate. I haven’t auditioned the repaired version but the original was one of the best cartridges ever. Tracked everything at 1g.

Just to avoid confusion for anyone wanting to track down one of the great B&O cartridges (they're not all great necessarily), bill K is correct, "MMC20CL".  I was incorrect, "MM20CL" is wrong.  The "MMC" part stands for "Moving Micro Cross", not Moving Coil.  It's an MI type.

I was hoping there’d be some explanation of the preamplification being used, since ceramic cartridge output V is dependent upon stylus displacement not velocity. So ceramics don’t need RIAA filtering in the phono stage.

@lewm 

If you look at the RIAA curve, you’ll see a sort of ’flat’ spot that isn’t duplicated by the constant amplitude characteristic. So you do need some EQ. If you look at a proper ceramic phono input, you’ll usually see a network that takes care of this.

This is the same issue faced by strain gauge cartridges, although some of them are built to accommodate the RIAA curve.

@lewm  : Philips had not much sucess with its cartridges. As a fact I knew Philips on cartridges thank's to the " euphoria " to discovery new MM cartridges in that long MM thread and I found out my sample GP 412MK3 through ebay. No other gentleman before me posted northing about Philips.

Well the GP 412MK3 is really good quality performer and Philips said that the cartridge magnet is : " magnet steel " and the cartridge is a MM with an unsual low output for a MM of mere 1.3mv.

This Philips and the Micro-Acoustics is worth to listen it and especially the GP 412MK3 not so easy to find out ( I still own it. ).
