Effective tonarm mass and the quality of the bearings will help drive your decision along with the end-product's ability to push enough voltage out to make the amps sing. If your lucky, meaning in my opinion only, to have a heavy mass arm with smooth bearings then a low compliance cartidge would be in order. And I do agree with the otheres, a low output is better, again IMHO, than higher output cartridges. I have been fortunate to have used a variety of cartridges, even a Stax CPX,, and I seem to be drawn to those that have a slight personality versus a clinical presentation. This is probably a result of most produced/studio records, espcially from the late 60s thru the 90s, the engineers rode their compressors hard, and peak leveled a lot of great music, and some of the more commercial records were recorded thru and mixed on less than desirable design boards - opamps with a zillion dB of feed back making the sound hard and brittle, at least that's my take. I haven't bought a new needle in quite a while so my price points could/will be off, I'm sure. At around $500, a couple to consider, first, ZU103 a MC, takes a well known product with known strengths and weaknesses and Zu mitagates most of the bad, very expressive, tons of snap/jump and a more forward presentation, a nice product w/o breaking the bank - solid product. Not sure if when you load down your phono/preamp for the cartridge if the dB gain in your setup is enough and if it swings big voltage, like max output 15+volts. BTW, loading is another one of those subjective things that I think is best done by the end-user employing trail and error, start at either 47K or at the reccomended load and keep changing it until it gives the sound you are hearing in your head, hopefully not voices telling you to do unthinkable things. Decca London, if it's even made anymore, similar attributues, very lively and engaging, draws you into the music, connects you, can be tempermental though and go away quickly as many have done in days of old. Its much higher output than most MC, its not a MM, the rather large cantiliver movers within a coil to generate a reasonable voltage output. Grado makes good stuff too, IMO they sound thicker/smoother and not as alive as the other two, but reliable as all mighty getout, basically, you probably can't go wrong with a Grado, it just doesn't jack me up. Out of the 3, I'd persoonally lean towrds ZU's version of the 103, assuming your arm mates well with it and you have ample voltage output to drive your amp, might have to twist the "V-knob" way up and hopefully it's noise floor is low - nothing worse than hiss riding on top of my tunes. On the cheaper side, Shure's V-15 replacement and Stanton's 681s were always good sounding - like a chain resturant - consistant quality, nothing fancy or outstanding but reliable, just not up to those previously mentioned. Also, I'd strongly suggest getting a record cleaning machine, it makes a big difference with the muck removed from the grooves.
