Does anyone have any experience with a Sutherland Little Loco?

I got the Little Loco a couple of weeks ago after speaking with Ron Sutherland on the phone about what cartridges and system I have. It replaced a Pass Labs Aleph Ono (circa 1998). I have used it with an Ortofon Rondo Red (.5mv output, 6 ohms) and an Audiotechnica ART-9 (.5mv, 12 ohms). Both sound very good but the ART-9 sounds much better (as it did with the Pass).
Remember, no loading with this stage because it is a transimpedance stage so no need. 

Compared to the Pass the Little Loco is levels better. Wider, higher, deeper soundstage, separation of instruments is much better, just a more natural, more 3D presentation. Not cheap but money well spent IMO.

I wish there were a list of recommended cartridges for these types of stages, I'd start experimenting

Quoting myself, there's a long and short version of my findings.

I ended up with a Soundsmith Sussurro cartridge, but the Low Z (Low impedance) version. I would suggest if you were to buy one make sure Peter Lederman knows it's for a transimpedance stage.

The long version is that I contacted Peter and he contacted Ron Sutherland and compared notes. Peter built a low impedance version of the Sussurro and sent to me. I didn't like it, thought it was rolled off up top a bit. Peter offered to refund my money but I told him I would prefer he try to resolve and asked him if he would be willing to put in the time to do that. He agreed and I ended up sending the cartridge and the Little Loco to him to work with. The results are as you would expect if one of the most knowledgeable and talented guys in the cartridge/phono industry had your gear on his bench...an excellent match, I'm loving what I am hearing. 

My comparison is the Audiotechnica ART-9 which sounds pretty darn good but not nearly as good as the Low Z Sussurro, and my digital: Innuos Zen MKIII and Bricasti M1 SE MDX (who names these things?!) DAC. 

I actually picked the cartridge and Little Loco up at his shop because I was in the area visiting family. Peter took me on a tour, we listened to music, talked about dogs...he's a great guy, I'm really thankful for the entire experience (and for sure I'm glad he was willing to take the time to make the cartridge sound so good).

Hello Lewm, I don't know what he did exactly. He did nothing to the LL, but made the Sussurro low impedance somehow. My understanding is that the canti, stylus, suspension, and body are all the same, not sure about the wire/coils/generator, etc.
