If any of you remember, I messed up the wiring on one of my drivers last month. I ended up having to resort to buying a new pair of drivers (didn't want to leave one new, one old). They arrived earlier this week. It feels good to be listening to my HD 650s again. I was going through withdrawl. It was pretty bad. Anyway, it felt like I was going through a brief burn-in period. When I first used them, it seemed as though the bass was lacking. Everything opened really quickly after I started listening for a little bit.
Currently, I have my HD 650s hooked up to my Fiio X3. I set it to high gain and set the bass to 2. They drive my headphones surprisingly well. I'd definitely recommend this simple setup for someone who doesn't want to spend a ton of money on a DAC and amp.
That´s what I love about Sennheiser, you can always get missing parts or new ones. That makes the product and service priceless (IMO)
I can imagine how it was for you, having some memories and getting to know your HP once again, I´m glad it all work out great. I listen to my HD650 with my DX50 on gain 2 and I like too the way it sounds. I know that there are some better options but for me, it works great when I´m working or doing something where I have to move and can stay at my desk
