Regarding the best pairing of the mz2 as a preamplifier with a power amplifier, I was looking at the Kinki studios monoblocks, and their website has this warning: "Our amplifiers are Direct-DC-Coupled without any capacitors in the signal path. This yields less colouration, high resolution, fast, and transparent sound quality. Should you wish to use other preamp make, please be informed that we do not recommend the use of DC-Coupled OTL tube-based preamp. The DC-offset of such preamp may fluctuate as the tube/valve ages and deteriorates." I apologize if this is an ignorant question, but the mz2 is a DC-coupled OTL preamp, correct? So this is a bad pairing?
