Just to offer my 2 cnts. There are 2 reasons I took a flyer for a third RS2T. As it has already been stated the first 2 were not workable. I sent them back to TMR, with a through explanation. They were great to deal with. If it were not for TMR, and their customer service, return policy, I would not made a third purchase. Charles and I had posted back and forth several times, and agreed the sound of the unit just cannot be beat. Once heard you will always remember its sonic attributes.
I asked TMR if they would open and thoroughly test the new unit before shipping, they had it for almost a week. Maybe I'm as lucky as Charles with this unit now, I HOPE! Having TMR as a dealer was very reassuring. Hopes this helps someone. Robert
