I do get exactly what you’re saying....if you want to enjoy poorer recordings there is a means via Roon to re-equalise their frequencies. I just think that the bad recordings are bad for a number of reasons related to mastering, too varied to fix with a few frequency adjustments. By the time I’ve gone to the trouble to fix the problem and analyze whether its fixed I just wonder if I should just accept that a few recordings aren’t great. I agree that some of the anomalies can be fixed (some can’t) but I think the ’fixing’ may be a greater ‘disturbance’ than the problem itself. For me, the biggest problem are mixes where instruments share exactly the same acoustic space, crowding each other, while the entire rest of the soundstage width and depth remains empty and silent. Such recordings sound like multiple musicians all standing in the same place. Such wasted opportunity. Conversely the ‘singer-songwriter who sings on one side of the stage whilst playing guitar on the other or pianos whose keyboards sound 12 feet long. Fortunately these are fairly rare.
With respect, I would say there‘s a big difference between the cable and some Roon presets. The cable treats the entire system and all recordings and once done, there is no selection (when to use it, when not) and therefore no analytical listening required.
I've never tried the Roon DSP, but I do use the DSP on my speakers (Avantgarde). They allow 10 bands parametric eq at 500 hz and below. I have it set for the room and simply adjust the bass gain sometimes per recording where more or less bass is beneficial.
I tend to avoid bad recordings (of which, granted, there are many). But, I don't let it bother me anymore as there is so much great music available through streaming that I haven't begun to explore. My experience is that Jazz, of all genres, has the best overall recording quality. Classical is all over the place but it's not hard to find good recordings. Alternative, Americana, Rock, etc is pretty disappointing with a mine field of good music compromised by mediocre to terrible recordings.
@spiritofmusic, I'll have to listen to the first King Crimson again-- streamed-- and see if was ruined. I have good memories of it on vinyl, in a smoke-filled basement at age 13!
