I have an Innuos Zenith mk 3 with the reclocker. It only made a slight difference in my system. I think the key is how good your DAC’s USB implementation is. I run a Terminator Plus which is known to have a great USB input. We all tend to look for sound upgrades to our systems that don't require large expenditures. Perhaps a better strategy is to bank that cash. and invest in better speakers that truly have a large impact on SQ.
