Was that based on using the onboard amp or the Hugo2 as a DAC feeding into your amp? Just curious. I had preordered one back at the end of Summer 2017 as an all-in-one solution but with the delays I ended up cancelling my order. I ended up getting the iDSD BL and then ordered the Holo Audio Cyan. But, that ended up being delayed so I'm back full circle to another Spring. I am just feeding it FLAC 44.1, but eventually I need to splurge on an upgrade to Amarra 4 to some software that can upsample to DSD. Tried Roon and JRiver and then did upsampling to iDSD BL. Didn't necessarily sound better than Amarra 4. Now that I have Spring I'm out of free trials for Roon, JRiver
. Can try Audivrana and HQPlayer to see the benefits of upsampling for Spring. For now, I won't be upgrading my computer so I just need some stable desktop player capable of DSD512 upscaling that won't drag down the whole system.
