I also was a late convert to Arnold and got to know his symphonies through the Naxos cd's. I have all of them and would recommend his work to anyone who responds to other 20th century composers like Robert Simpson. My favorite is his 7th but would probably advise most newbies to start off with something a little less dark (probably the 5th). I can't compare the Naxos recordings to other versions but they are well recorded and they had my complete attention. Thumbs up from me.
