Is 60dB gain enough for Kleos?

At age 52, after years of technological philandering, I am once again courting my old vinyl flame. I just bought a VPI Classic 3 because it looks like it was built in the fifties, like me. Now I am obsessing over the selection of cartridge and phono-amp. Every man needs his irrational, unsubstantiated religious beliefs, and mine include vacuum tubes (very fifties-ish) and a transformerless signal path.

So let's say that for the moment I am enamored with the Fosgate Signature phono-amp, which having a 60dB gain without any input transformer. Now I have read that this works best with a high-output MC in the 0.8 to 1.0 mV range.

Here's the rub ... I am very intrigued by the Lyra Kleos, my fascination with which is due in no small part to the musings in these pages of J Carr himself. Alas, the Kleos has an output of only 0.5 mV. So I seek the advice of those who might have pertinent experience!

Theo, are you using the Linto without a step-up transformer? If so, that is a good testimony indeed. I trust you hear no compromise of dynamics?

Regarding downstream compatibility, I will at first be feeding output of the phono amp into a Marantz AV7005 pre/pro. I could not find a line stage gain spec for this unit. Input sensitivity is claimed to be 200 mV / 47k-Ohm and pre-out is 1.2 V unbalanced, 2.4 V balanced … I don’t know how to translate that into gain. I’ll be using the balanced output into a Parasound Halo A51, sensitivity = 1 V for 28.28 V. Down the road, barring insolvency, I’ll insert a nice preamp with a threatre bypass mode into the stream, probably a Parasound JC-2 (gain 14dB) or a Rogue Audio Athena (gain 15dB balanced.)

Al, thanks! Since the reviews I have read of the Fosgate, albeit sans actual measurements, consistently cite quietness for its genre. So far, then, so good! If I've read it once, I've read a thousand times in this forum and others, that meaningfully auditioning of high-end gear, especially for vinyl playback, is a very tough thing to pull off. All the more so for me, who lives hundreds of miles from a major city.

Jwpstayman, just for the record, what cartridge have you favored on your JMW arm? My target investment is $2k to $3k. My preference, if forced to choose, is speed and dynamics over lushness, although having everything without compromise is always best! :)
