Ive got a Sony TAFB740 (http://www.avland.co.uk/sony/tafb740/) Ive been running my current setup for the past month or so, and I havent run into any problems. Even with all the speakers on and the amp running at a about 10 o'clock. This is my current setup : Speaker A Switcher Box ^ 1. Tannoy R2 2. Kef Cresta Speaker B Switcher Box ^ 1. Mission M72i 2. Kef Coda 70 The Tannoys, are in the living room, the missions in the kitchen, the Kef cresta's in the conservetory, and the Kef Coda in the office. It may seem abit weird, but It fits my need pretty well. The amp runs alittle warm when everything is on, but it has never cut-out or anything. Am I creating a fire risk ?
