I've been using Audirvana and have been creating no-audio proxies so that Itunes handles my library. So far, its the best system I've tried cause Audirvana sounds superior to everything ive tried and the Itunes library management is wonderful since I can control my library on my phone! 

Between my roommates and I we've set up a pretty comprehensive integrated media center and I've took the time to photograph everything so I thought I'd share! Sorry if I posted it to the wrong section but i thought this post would get some good discussion regarding headphones so I posted it...

Yeah, I've been using audirvana plus, definitely the best player for my needs.

Pick me, pick me ! :) Thank you hifiman

  You're absolutely right. However, I've always believed in function over form so I'll be sticking with Audirvana!

Alright so it looks like audirvana is the best option for both sample rate switching and flac support. Thanks for the responses! 

Well their overall characters are pretty similar, also the sound signatures are similarly shaped but I was just pointing out the slight differences between them (no two cans can sound the same).   

Yeah having flac in my library is a big thing, any solution to this?

It's funny that you compare it to the dt990s cause I actually think they're closer to the dt880s. The fidelios probably have a more natural midrange, punchier bass, and are slightly darker but their sound signatures are very similar. 

My roommate had a pair of dt880s 250ohm and my good bud had hd600s so I've become quite familiar with their sounds. Overall, I'd say that the hd600s beat the dt880s in almost every way (especially when amp'ed well). The neutrality of the hd600s is great and if you get a nice tube amp like the...

I bought a audioquest tower cable for my X1s and they improved the sound a lot too! Also, you should look at getting a dac/amp combo; my X1s sounded a billion times better coming out of my schiit asgard than it did coming straight from my computer. 

I have a pair of hd650 driven by a crack OTL with the 5998 as the output tube and absolutely love it. I provides great detail and superb depth. It even boosts the treble up a little on the dark 650s which is very nice! I'm looking to get a 7236 tube just to compare the two tubes but can't find...

So I'm looking for an application that organizes my audio files presentably, something that can handle a variety of audio formats(16/24bit up to 196Hz), read a variety of file types (flac, mp3, aac, etc), and most importantly, a player that switches the audio output format according to the file...
