I purchased a Benz Micro ACE low output for my Basis 1400. It has an Origin Live RB300 tonearm. My phono preamp is an Electrocompaniet ECP-1. I'm very happy with the cartridge, and glad that I didn't go with the Dynavector. I thought the Dyna was a little too much on the top end and lean on the low end. The ACE is even handed from top to bottom, and the backround is BLACK. Detail retrieval is excellent and the soundstaging is superior to many CD rigs regardless of cost. It's not the best, but it is a hell of a lot of performance for the money, and you would be hard pressed to do better at or near $700.00. How will it work with the Rega? I couldn't tell you, but I doubt very highly that the results would differ that greatly from the Basis.
