I run Roon core on custom server using Euphony operating system. Euphony has the ability to run HQPlayer inside Roon in both 30 minute free trials or purchased full version. In my setup I prefer running Roon sans HQPlayer in 'bridged' mode, where Roon core is on the custom server, Roon Endpoint on my OpticalRendu streamer. HQPlayer simply sounds more 'processed' or hifi like vs my favored Roon only setup. I also minimize any of the 'extra' processing Roon provides, therefore, none of their inferior to HQPlayer dsp, no volume leveling, no volume control, no or throttling of their individual tune or library analysis.
Its been my experience that all this 'extra' processing only emphasizes the digital nature of digital, Yes, there were certain aspects of sound that seem improved in the short run, especially when my digital setup wasn't fully realized. But over the years as my streaming/digital setup has improved to where it now competes favorably to my pretty nice vinyl setup, in other words now finally sounds fully analog, I don't want any semblance of a 'processed' or digital sound to reappear. Based on my experience I now judge HQPlayer as benefiting digital setups that need band aids to cover up for deficiencies somewhere in streaming or full system chain, Get your entire streaming chain in order, this means all the way from internet service through dac, and of course we also need to get our systems and rooms in order which further negates the need for dsp. If you don't need 'help' with resolution, transparency, tonal balance, timbre, in room frequency response at listening position, dynamics whats the point of HQPlayer? Sometimes less is more.
