Dear @lewm : I own all the RR LPs and yes maybe not the best Artistor scores but very good to excellent quality sound levels and no it's not mainly Jazz but different genres.
In my personalcomparison tests wide proccess I use one track ( part of it ) in the 45rpm Dafos RR: Gates of Dafos is the track. I live Eileen Farrel RR recordings.
Some mentioned Janis Ian Breaking Silence, I use too 2 trakcs of the LP ( part of it ) in my comparison proccess.
Btw, here the today RR catalog, unfortunatelly no LPs down there only digital. Dr. Johnson ( Spectral electronics. ) was rhe first to made a D2D CD.
Regards and ENJOY THE MUSIC NOT DISTORTIONS
