I saw a huge DCC sound layout at the Farnham show (Falcon Road, BR blue diesels), and I have to say I'm still not sold on DCC sound personally. They all sound great, but for me I need the rumble, the rush of air as it passes, all the stuff that is impossible to accurately recreate in HO. Although I will say, and I hope I'm not shot for this, American sound locos do sound better than UK sound locos, and diesels sound much better than steam. Just my opinion of course. I would never try and talk anybody out of DCC sound.
