Many tube based MM phono stages use 12AX7 as input gain tube. 12AX7 has high Miller capacitance, so I don’t know how you’d defeat that . This has been going on for decades(mating a SUT to a 12AX7 input). Do you see it as a real problem?

I did check with Aric. He recommended of 1:10 winding and did not see any detriment to do what I have planned, from the SUT perspective anyway. sumiko/project looks very similar to the Kleos, but I suspect the quality is not nearly the same. @jcarr are we speaking to compliance resonance issues for my arm and the Lyra? KLEOS Dynamic compliance: 12 x 10-6 cm/dyn (@100 Hz?) at 8.8 gm SUMIKO Songbird low MC is a cartridge often shown with my TT. 12×10-6cm/dyn @ 100Hz at 8.5 gm and it’s about $1000 less and cost Both of these cartridge/arm combinations resonate at ~11 Hz. (that’s high no doubt)I can do the hard math, but I haven’t yet and doubt it will make any difference to that aspect |
@michaellent : Only take in count that the calculators in the net for the tonearm/cartridge frequency resonance takes the compliance at 10hz not 100hz. So, the Kleos has a compliance around 19 cu.
Btw, I own the Kleos and never heard the Songbird ( I owned 6 years ago the top of the line Sumiko. ) and I can tell you that the Kleos is an excellent quality performer.
