I am presently limited to MM or HOMC by my preamp. I have two arm wands, one with an Ortofon OM-30 Super, and one with a Denon DL-160 HOMC. The Ortofon tracks a little better, but the Denon offers a wider soundstage, more detail retrieval, and is smoother from the mids on up.
And you? What pickups do you like in your 166?
