I have owned many fine speakers since the 1970's and sold high end audio until the early 2000's. There has been a seismic shift towards analytical sound in the effort to chase details in my mind since that time. I have a nice digital frontend, but it is only for background listening as I still far and away prefer my analog rig to relax and enjoy my music.
There is no doubt my room is a weak link in my system, but in 30 years listening in this very room, I have never experienced this type of tipped up sound. It is not a small room measuring 16 by 24 with 10' ceilings, with a fair amount of soft, somewhat plush furnishings. These speakers were so hyped I thought it would be an obvious fit as I have always enjoyed many different British speakers.
The most logical fix is to replace the speakers, but in this day and age that is less easy as we have fewer and fewer quality B&M operations.
Looking for a band aid that probably doesn't exist in this case.
