I am a new member looking to venture into more high end audio. I currently use a gaming headset (Astro A40) mainly for gaming and my main audio enjoyment. I recently tried on a friends Sennheiser HD 650 with schiit stack dac and amp and was blown away. So for the last few days I have been reading forums and reviews non stop looking for a pair of cans for myself. I loved the sound quality of the 650's for listening to hardstyle and edm except for i was looking for a little more bass. I also liked the few metal songs i listened to and was amazed at the sound quality of all the instruments vs what I am used too.
So i am looking for something that has the highs and mids similar to the 650s, but packs a little more bass. Also they need to be closed back with minimal sound leakage so I can use them in the office I work at. My price range is roughly $700 for headset with an amp and dac or a bit more if it is really worth it. If it is impossible to achieve the same sound quality with a closed back set then what would recommendations for open back be?
My friend directed me to Ultrasone Pro 900's but I have read many mixed reviews and am very unsure of what to do.
Thanks for any help.
