@snackeyp Thanks, It's been a nonstop marathon of music playing since I've received the May!
I am (and have been for 20 years) running source direct to my amplifiers because I have no analog sources to speak of, and have always preferred the more direct and detailed presentation that running from my fanless/silent running media server directly via USB to DAC and from DAC to amplifier. I co-designed several of Niveus Media's earliest fanless/silent running media server designed to operate seamlessly in an audio rack in the living room. This was a couple of decades ago believe it or not!

The May DAC connects via USB to a brand new custom silent-running and completely fanless Sigao Model B dedicated Roon server that has a
10th Gen 10-Core i9 10900T Intel Cpu, 4TB Samsung SSD for music library, 512gb Samsung 970 Pro NVME O/S/Roon/HqPlayer drive, 32gb DDR4 2666mhz, a separate JCAT FEMTO clocked USB PCIE add-in card (not in use atm because it doesn't support 1.536mhz or DSD512/1024 upsampling currently, but fortunately the Intel based USB ports do support the higher rates).
I use Roon to feed HqPlayer software a 1.412mhz or 1.536mhz or DSD512 upsampled signal using their proprietary filters to the Holo May in NOS mode. I control the volume through Roon which attenuates it in HQplayer since the May Dac does not provide volume control.
I power both the Sigao Roon server and JCAT USB Card separately with with a multi-rail dedicated 300w HDPLEX Linear Power Supply and that is plugged into a dedicated Equitech Son Of Q Balanced Isolation Transformer.
Certain DSD512/1024 filter settings in HQPlayer can be very taxing on even the best CPUs hence the need for a 10/Core processor.
