Bought a set of Tannoy HTS-101 speakers and subwoofer from Peter Tyson last week and although the sales service was excellent over the phone I've felt a bit uneasy since (hopefully unfounded). After setting up the system I noticed a constant hum from the sub and it wouldn't go away unless it was switched off (even without RCA lead in it and in all plug sockets in the house). When contacting them just 2 days after receiving the goods I was told that when they receive the sub back they will try it out and see if they can notice the problem, if so they said they will either service it or replace it. Maybe I'm wrong here but for something that is less than 7 days old, I should be expecting a straight replacement anyway shouldn't i? Sorry to ask but just wary as not bought something so expensive online for a while.
