Crazy... I have the Gyro SE with Shelter 501 - which I believe is .4mV not .3mV. I any case, it has plenty of gain with my Plimius M14 phonostage (60dB gain for MC) and Lamm LL2 preamp. Another tweak I tried with the gyro is to use very stiff springs and washers under the armboard in place of the solid spacers. This allows infinite adjustment of VTA and azimuth (even while the record is playing if you're careful!). I've been warned by Gert that this could intoduce some noise in the arm as springs can "sing" but the only singing I have heard is coming from me as I listen to my LP's.
