Hi I think most dealers try to sale more expensive components vs solving basic problems like room acoustic. i know a body that he spend over 200,000$ for system and if you see his room you think the man is so crazy because his room is under standard for listenning. after 6 month he say to his dealer that sound is not very good and dealer tell him you should change your speaker cable and i give you a 8000$ cable for solving problem he buy it and see sound was better but never undrestand basic problem will effect on his brain in long term. i think hifi business is one of most unclear business in the world. what's your idea?
