I don't myself know of any Shostakovich lovers that dismiss no. 14. My general impression is -- providing you accept it as a bona fide symphony in the first place -- that it's among the most highly regarded and I would also rate it highly, especially "Tri Lilii". On the question of original language or Russian throughout, I am somewhat undecided though I don't think Haitink would be my first choice (this cycle is in general a bit too cool in Shostakovich for my taste).
