No impact for me. I’ve been in Information Technology for the past 30 years, networking and security. I have access to numerous recently retired computers and all the skills need to fix/replace, tune bios settings, etc.
I just hear about all these tweaks done or specific motherboards selected for low noise, along with the ability to power it with a linear power supply, that I get curious.
I have absolutely nothing broken, I’m only interested in spending the money if I gain SQ.
I have a STi5. Nice piece of kit and I use it for Roon. I’ve purchased several servers from small green computers over the years and service has always been excellent.
I don’t think the STi5 will change the sound quality over your current setup. The beauty of these players distributed away from the computer running, as in Roon, is as long as player/DAC receives a bit perfect stream, you’re good.
