[Diligence]

Hi I Just Purchased the Beyer 990 was looking to use with PC only option' read loads of reviews and tips and models ect.. but I Really don't wanna go Tubed because I Will have the DAC in shelf under my Desk, only Complex thing am having trouble with is what can power (600Ohm) they almost Seem Useless, as I Hear on Reviews. but just to be Clear this is my First High End Headphone, it's for Music Production, Because Monitor Speakers are to loud as I Don't Live Alone So if anyone can help under £200 Budget if possible Thanks for Your Time !
