Or you just wanted to buy something new. You had the TH900 for how long? After that amount of time with it then you realused it had too much bass? You could have just gotten a Hugo.
I've had TH900s for about 3 years now. I currently use them with Chord Mojo.
Before I got Mojo about a year ago, I used them with Schiit Bifrost Uber and the Bakoon. Before Bakoon, I had a Schiit Asgard 2 I listened to the TH900s with.
I used the Uberfrost/Bakoon combo maybe 1,5 years before switching to Mojo, because I wanted a simpler and smaller system.
I'll probably go for the Hugo 2 in the future, but before that I'll get another pair high-end headphones. Both are not high priority on my list of future purchases, as I have other things I need/want more.
