M030 ISS Issues & Questions. Pls help thanks!

Hello. I recently bought a pair of the M030s. Although I love the sound I had a potential issue with ISS and a few questions. Your help is appreciated ;)
1. When I woke up in the AM, I noticed that 1 monitor was on and the other was off. Without touching my computer, the other monitor went on about 5 minutes later. It seems that they are randomly waking up without any source input. Is it possible that there is some very slight, unnoticeable noise going into the monitor waking it up? The computer is in sleep mode (Apple iMac). I'm running a Apogee Duet directly to the 1/4" jack inputs. Please advise!
2. Is it better to use XLR or 1/4 inputs with these? Will I get better bass response using XLR?
3. When using a foam shelf with a metal top, I noticed slightly less bass than when put directly on the tabletop. Although, if I use the angled shelf, the tweeter points to your ears, you hear more treble/clarity, but lose some bass. Is there a way to get full bass while tilting it to your ear at the same time?

Many thanks!!
Mike

Hello Mike,

Thanks for your questions. :)

1. It is just as you suspected, even a small noise or disturbance in the signal can wake up the monitor or prevent it from entering the ISS state. This can be easily tested by disconnecting the signal cable from the monitor.

2. No difference at all.

3. When placed on a table or shelf, the bass and low mid will be boosted due to boundary loading effect. Although this huge bass boost may sound pleasing at first but actually this is not desired and must be compensated by raising the monitor off from the table surface, tilting them towards the listener's ears and using the room eq switches, assuming that you want reference quality flat frequency response.
