Tyson - I have most (not all) of the Dorati/Philharmonia Hungarica set on CD.
When I listened to Sym 27 on my more resolving system (with Janszen electrostatics), it sounded a little thin but not harsh. Fortunately, I have a DSP preset with about -1.5 dB tilt from ~1800 Hz to 20 kHz. Selecting that did make the recording more fun to hear. So, I agree with all who said: Nice performances, but not the best recording.
Two systems also at my house: My #1 system (downstairs) is more resolving: many recordings sound superb, and a good number sound pretty lousy. Sometimes DSP can give a work-around, sometimes not. The #2 system (with Harbeth P3ESRs + sub) is certainly more forgiving and great for less focused listening -- though I could imagine setting up the Harbeths better if (when?) we downsize, and getting a more purist result.
I agree also with all who noted that it's nice to have two systems. In my view, the change of perspective tends to refresh the ears.
