@mahler123 reading your post made me realize I have not listened to the Razumovsky quartets in about 20 years! These works were a favorite of my late wife but I think that after her death, perhaps I avoided things with great emotional attachment for her, to avoid a breakdown.
Also I have not listened to the Dvorak quartets in many years, I have the Prager DG set LPs.
I counted up, I have a dozen or so recordings of the Beethoven quartets between LP, CD and flac. Not all are complete. The Vegh LPs are played most often.
The Shostakovich quartets are an interesting case, I have the Fitzwilliam, French, LP set, and listen to the Borodin's performances (streaming). I think back to a discussion with a coworker who was a Jazz fanatic who maintained that classical players were not really musicians because they "just played the notes" - the two interpretations of the Shostakovich could scarcely be more different.
I realize, I cannot expand your list, I get drawn back to the late quartets, and it seems that at least one a week I have to listen to the Heiliger Dankgesang - for me the most emotionally affecting piece in all of music.
Now, if someone could explain the Große Fuge - does anyone have a "must listen" recording of that? My mind gets lost!
