It’s a bug in Pike’s Peak. CD’s with preemphasis cause it. Sorry about that. I don’t know if PS Audio will be releasing a patch (considering the work to retest the sound quality of a release.)
The PWT is good about informing the DS about preemphasis, if you rip the CD the preemphasis indicator will probably be dropped on the floor and the CD will play (tho with way too much HF loudness, some of us don’t find that to be a problem anymore )
Also foobar2000 and JRiver can be set up to do the deemphasis with appropriately tagged files, tho I’ve never pushed it thru so I can’t personally help on how to do it.
