What cart you match it with now? You using the Carinet too?
I don't have the Clarinet, it may be next year's project for me. I do think it is a great design and would like to hear how it does in the system, especially how it may modify the sound of the DAC unit I have.
My cartridge is an Audio Technica AT440MLa, not too expensive (if you look online) and am very happy with it's ability to track very well and produce a good 3D soundstage.
