Cheers for the info Doc, that switchbone is a great bit of kit but unfortunately a bit out of my pocket, i've been speaking with Brian Price at Loop Master and i'm gonna go with his 'single loop, a/b-y with tuner output' it's just what i need and at 25% of the cost of the switchbone, more power to my pocket :D reviews of his gear on Harmony Central are nearly all 10/10 so i'm gonna give him a try, Thanx again for your input :)
