Absolute top tier DAC for standard res Redbook CD

This is the thread that convinced me to purchase the QX 5 unheard, while I cant chime in on the different dac,s  being currently discussed I can chime in on the optical ethernet vs straight ethernet or USB and yes the optical ethernet gives a much better portrait of the music in dynamics, soundstage, detail and air. I with back and fourth lately between USB and optic for the fact Im burning in a new preamp and its running 24/7 so during the night time I switch to the USB and when I switch back to the optical ethernet thier is a clear difference in those areas especially transparency. There is also a difference in volume levels between the two in my set up with the ethernet being a few db louder.

I feel the difference in straight ethernet vs optical is in the midrange on up, a tad more transparency and natural timber, bass is fantastic in both.

Yes' there is an improvement using LPS for the router and FMC , Im using the W4S LPS1 and do not know if its fast acting or not but there is clearly an audible difference with the LPS then without. I even have the LPS,s plugged into a power conditioner. 

For the FMC nearest the Dac I use a battery. I actually have 2 batteries for this so when one runs down I simply hook up the 2nd battery.

I look forward to your review of the Shunmook Giant Diamond Resonators, been interested in these for some time now.
