Lyra and OMA


My first endeavor into moving coil. I’m thinking of a Lyra Kleos MC Cart and OMA SUT. Anyone want to speak to that. Please?

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. 
also: FROM ARIC: Hi Michael, My MM phono stage does not use any capacitors at the input so there’s no worries regarding connection of SUTs.

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
Please tell me what I missing. Before I make a mistake. I know just enough to get myself in trouble. I’m chasing this because of the dynamic range of the cartridges’ is vastly different at the low end. I listen to classical music and rock.

@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.

 

Regards and enjoy the MUSIC NOT DISTORTIONS,

There are calculators and there is experience. Maybe JCarr knows a little ;)
