@lowrider57 thanks.
I think you’re right about needing to tame the vibration coming in to my gear. That seems to me to be the most obvious - it’s harsh on the top end when the dynamics are loud. I’m pretty sure it’s not my amp clipping though it sounds like it. As I don’t have any control for that in place, I’ll start there. My local dealer should be delighted to sell me more gear.
I also stand by my other comment that many recordings are brighter than they ought to be. Treble energy dissipates in the concert hall. However, the way orchestras are recorded - with a mic at most stands - does not recreate the balance heard mid hall. The mics are capturing what the musician might have heard, but not the audience.
Like some others here, I have many wonderful performances of great music performed by stellar ensembles but recorded under the DG label. The sonics are beyond disappointing. Fortunately, Qobuz has brought to my chair a fabulous array of alternatives - and I needed help from this group here to sort through them to find some that are better balanced.
Best,
