Roon recommends 1.3X as the minimum safe processing speed, especially when using DSP functions.
Since I started upsampling to DSD 256 with convolution filters, my STi5 - based core is running at around 2.0-2.2X, and getting pretty warm. Other than the heat, it runs fine and sounds great. Only once has it cut out, when it was located in a warm room and I was running headroom adjustment which brought the speed down to around 1.5X.
But SGC is telling me I need to use DSD 128, instead of 256. processing speed needs to be > 4X. Or I should upgrade my server to their i9 model…
Are they just trying to sell me a new box or should I be avoiding DSD 256?
