One other possibility. Have you tried optimizing VTA for these "supposed to be good" recordings? If arm height is much too low you could be losing the top end.
Suggestion for more detail
For the recordings I have both LP and CD versions, I notice my analog setup beat my CD setup for almost all of the recordings. However, on some recordings, the CD versions sound more colorful and detailed than the LP versions. Is that because of the condition of records? Will a upgrade to MC cartridge help?
My CD setup is Spectral 3000/2000 with Spectral-Link.
My Analog setup consists of clearaudio Virtuoso Wood, Eminent-Tech ET-2 with all upgrades except the Mag. arm tube, single Wisa pump and tank, Eurolab Premier with 80mm platter and Teres DC motor modification, HMS Gran Finale phono cables, Tom Evans MicroGroove+.
