Description Of Issue
44k Upsampling to DSD512-dropouts.
A little history, I had been using an SGC 1st generation i5 with ROON for a few months. It was working great, was able to handle upsampling without any filters to DSD256 with ease. Since my DAC can handle DSD512, I thought I’d like to give it a go to get something faster since the SGC i5 couldn’t handle it. I opted for the NUC8i7BEH which I put together yesterday. I let it run all last night getting the library together, restoring from a fresh backup taken off the i5
Today I had my first audition of the fresh new NUC. I enabled upsampling to DSD 512 for 44.1K, DSD256 for everything else. I played several 44.1K tracks from the internal SSD drive right from the start. Whatever I threw at the new NUC it played just fine, for about an hour or so.
I started to get dropouts on a 24bit 44.1K track off of Tidal. Then thinking it may be just the track, I tried another local 44.1K 16bit track, dropouts as well. Processing speed is 2.1-2.3x at DSD512. Changing upsampling to DSD256, dropouts vanish. NUC is hardwired to the router. Changing ethernet cables, controlling the NUC with an Ipad or local PC via ethernet etc, same issue.
I have no filters enabled, headroom adjustment to -3db enabled or disabled same issue, Parallelize Sigma Delta Modulator enabled, Enable Native DSD processing on or off, same issue. Is it that this NUC can’t handle this type of upsampling, or am I missing something?
