I use a G1, and really, really want Roon to sound as good as LDS. I feed both Roon and LDS from the same network-based hard drive. There was an upgrade last year in the way the G1/G2 handles RAAT, and that made an improvement.
But to my ears LDS still sounds better. I try to convince myself that it is simply confirmation bias (from reading about other’s experiences), but when all is said and done, LDS sounds less “digital” to me.
Maybe it has something to do with the extra server that Roon requires? Maybe there’s some kind of interference that the extra server produces in my environment? I have found that setting “Bypass All Filters” on the DSP page in Roon makes Roon sound closer to LDS.
This will drive some people nuts, but on a PS Audio DSD one can confirm “Bit Perfect” delivery of a particular test file. Both Roon and LDS pass that test. So whatever is making the difference has to be coming from interference via ground loops or in-band noise. When talking about 24-bit resolution, one is talking about a theoretical 144 db of dynamic range. There’s room within 144 db for the very most subtle noise/interference-related injection. Maybe that’s what some of us are hearing?
Regardless, bottom line, for me in my system, LDS remains my choice for critical listening. Roon suffices otherwise.
