""I've used Smart Home Sounds again to purchase a sub to go with the playbar and play 3's I bought a year ago. I cannot fault their service, once again I received my product less than 24 hours after purchasing and they were on hand to give me advice through their online chat with regard to the sonos 15% promotion. I have used other retailers in the past for sonos products but would only use Smart Home Sounds from now on as in my opinion their service cannot be beaten. I'm so pleased with my sub, I didn't believe it could make such a difference to an already great sounding set up. I cannot recommend it and Smart Home Sounds highly enough.
