I hardly think so but i dont know This is a great forum and forgiving community despite ( Bose just being Bose  ambiguous mostly ) my 301 and 901 relationship is 45/ and 40/ years old respectfully I will be enjoying L1 model 11 just in retirement analog mode no instruments just a tall hi fi  to announce my dedication to  pre recorded  tunes. very best Jack
