The SP20 is really nice (at 4X the cost)

To be sure, the SP20 adds a phono preamp, etc.
I'm not sure what Reina means, though, when he says, "The result is the SP20 ($9000), a fully balanced, pure class-A preamplifier that uses no overall loop negative feedback."
Is "no overall" feedback the same as Zero feedback?
Meanwhile the Athena claims THD+noise an order of magnitude lower than the SP20, i.e. 0.00012% vs. 0.002%. Per 6Moons they claim "Low", not zero, feedback. But I'll wait for Amir to the measurements to confirm the Denafrips' claims, (I might have a long wait).
Anyway, I don't suffer from 'feedbackphobia' to the extent you do.
