I started with some beats last year (yeah I know). Then moved up to the 20$ mono price MEP-839 Pro Headphones. Yes they were better than the beats. They were no loud enough especially watching youtube music videos. I ended up buying a little bear 12au7 amp that helped a ton. When there is no imput they sqeech sometimes. I have tried various ebay tubes but not much improvement. Switched all my MP3's to FLAC and that sounded even nicer.
All was good until I decided I wanted some real over the ear headphones. Found a deal on new dt990 600 ohm and got them in the other day. They sound great but anything over 50% the bass gets real washed out and muddy. The monoprice phones would boom like a bassed out lowrider (not saying that is my goal, just saying). Im not sure if my amp is not delivering enough power, the headphones are defective or I just want to listen to them too loud. Anyway I love the sound of acoustic guitar, and brass insterments on the dt 990's. I'm hating it that I cant even play ACDC thunderstruck at a decent volume to rock out without getting muddy bass.
Tips and suggestions all appreciated. Ohh and nice to meet you guys.. I tried to lurk for the last month but Im pretty much over my head :)
