It has one 1/4 inch jack and one 3.5mm jack at the front end - can both be used at the same time without any damage to the headphones or the amp itself?
Has anyone done this and found it works alright?
Can the 2 headphones be of different impedance ie. 16ohms into the 3.5mm and 300ohms into the 1/4 inch?
Does it degrade sound quality if this is done?
