Cartridge for VPI Scoutmaster and Bottlehead gear.

One thing everyone needs to keep in mind is the OP's Seduction phono stage has 40db of gain and is locked at 47k with 50pf capacitive loading.

I would go with a Shure V15 III, IV, or V and the Jico stylus; shoudl run in the $300 range and work fantastic as Grinnell has already pointed out. The low capcitance of the Seduction does something magic to those Shure's...

If you just have to go "new" then a Ortofon 2M Black would be very nice too.

I love the Seduction and don't think you need to upgrade it. The Eros is MM only too.

If you really want to go the Low Output Moving Coil route, then I would suggest getting a step-up-transformer (SUT). The SUT will allow you run MC carts through the Seduction without problem.

The Dynavector 20 is a fantastic cartridge, I didn't care too much for the Blackbird, myself. The high output DV-20H **MAY** give you enough output to run through the Seduction, but it's only 2mv if I remember correctly and that's going to be pushing it with the Seduction.

The more I've thought about it, if it were me, with your musical tastes, I'd do one of the following:

MM:
Shure V15VMR + Jico SAS (~$300)
Jico SAS-MM1 (~$240 and FANTASTIC!)
Ortofon 2M Black (used ~$400)

Or, add a tad to your budget and get a Bob's Cinemag SUT (~$400 new/$275 used) and a Dynavector 20XL (~$300 used).
