I don't know whether my 271 is faulty, but I have found that if I power up my speakers first (I routinely do not leave them in Standby) they just go into standby. If I then manually power up the 271 by pressing its power button, the DSPs go to 87 (as specified in the 271's configuration). If I use the Meridian IP control app to power on the 271 from standby (assuming it was in standby when the DSPs were powered on) the DSPs go to 65. As has been commented, a stab at the volume control and the DSPs leap to 87. If Rick of Audio Images is reading this then I think we could do with his omniscient comments.
