I'm using a Rega Saturn in my main 2-channel Linn stereo, and the Saturn is fantastic! Prior to acquiring the Saturn, I was using a Pioneer BDP-51FD as a CD transport into my Linn AV5103 DAC, and while the Pioneer and Rega are in different leagues, I'll state the obvious that the Saturn was an incredible upgrade. My ears (and my wife's) heard noticeably more detail and separation across all frequencies. I had been previously skeptical of high-end CD players like the Saturn, but I'm now a believer in their merits.
For reference, my Linn system consists of the AV5103 processor, 3 Aktiv AV5105 amps, and AV5140 Aktiv loudspeakers. I'm using the analog outs on the Saturn.
No doubt you'd gain similar results in a resolving headphone system like yours.
I'll be curious to hear others' opinions.
