Going around in circles trying to choose the above. Will be used for PS4 and XB1 use. Mixamp ruled out as previous experience reminds me that the amp isn't particularly gutsy? Will be using with Sennheiser HD58X and AKG K712 Pro. Been thinking along the lines of the Creative E5 or G6 - anything else around £130 I could consider (Virtual Surround not essential!).
