I agree that DCC sound is not everyone's cup of tea
however I do love the sound factor and in particular
the 071 chip,that said it will do your head in after
a while,and a least you can turn it off.I have 071,201
141,and A class chips and its the A class that runs best
for long periods of time with that nice gurgle sound.
For me the MSB 071 sound is far better than the MM
Version from what I have heard.I love having my 071
ticking over in a siding or shunting cement wagons.
