Need advice for a replacement phono cartridge

For the Little Loco you want as low an impedance cartridge as you can get.

My Sonic Lab, Lyra and Ortofon make cartridges that will work well with your phono stage. I think the Ortofon Windfeld Ti would be an excellent choice. If you have a VPI unipivot arm you will need to replace it with their gimbal arm for the best performance.

So, the cleaners destroyed my phono cartridge yesterday while dusting even though I’d cautioned them against dusting my stereo.

Same story pops up regularly. Telling them not to dust the table does nothing. Guys, the only way to protect your cartridge is to SECURE access to it (or the whole turntable) before cleaners come over. Arms with removable headshells or arm wands are handy since they can be locked in a drawer. Sorry for your loss :(

Herb from Stereophile loved the Benz SL (iron-cross, wood body) with Little Loco, so any of their iron-cross models should be a great match. I have Zebrawood L and Ebony L - they’re excellent, and regularly available new for a really good deal in the classifieds here. The higher end models (Ruby, Gullwing, LPS) use a less efficient ruby plate and may not be a good match for the Loco (they certainly don’t work well with a SUT).

I also love Koetsu; they’re a little sweeter than Benz but cost more too. Should also be a good match for LL. Ortofon is good too, though I find their MC models have a little more variance in sonic balance than other brands (Cadenza Bronze, A90, Windfeld Ti here). 

I would send it to Soundsmith or other cartridge rebuilder I had a Sumiko redone where the cantilever was completely broken off. There’s always hope.

There goes the cleaners Christmas tip.

Some of the better Benz cartridges have a fairly high internal resistance and are not well suited to a current driven phono, eg, the LPS (38 ohms). On the other hand the Ebony L would work (5 ohms). Check specs and try to stay below 10 ohms internal resistance, no matter what LOMC cartridge you choose. HOMCs need not apply. 

Another vote for repairing the cart.  Where ever it ends up you will need to wait. I had a Koetsu RSP get its cantilever removed by the same mechanism.  Peter Lederman at SoundSmith repaired it after a several month wait.  It has been working great (and still sounding like a Koetsu) ever since. 

Because of the wait, picking up a cheaper low internal resistance cartridge in the meantime makes sense.  Have fun exploring something new.
