Advice on new gear

[Azsamael]

Hey there guys, I am completely new to this world of awesome audio.
It has been a year or so since I bought a pair of Audio Technica A900 headphones, and a Fiio E7 DAC/amp. I play mostly FLACs from my PC to the E7 to my headphones.

The thing is now I have have free cash that I can spend and thought it would the be the perfect time to upgrade a little.

Now I have been looking into getting a DAC, but for the life of me I cannot choose one. I have also been looking into getting a tube amp, since I have wanted one for a while.

So far I am looking into the following DACs:

- DACport LX
- Schiit Bifrost
- Maverick Audio Tube Magic D1
- Music Hall Dac 25.3

And these amps:

- Schiit Valhalla
- Little Dot MK IV Tube amp
- Woo Audio 6 (maybe with the Sophia Princess upgrade)
- Schiit Lyr

Leaning towards the Bifrost and the Valhalla, but if there are any other suggestions it would be great. Also, I don't know about much tube rolling or any of that. Any help is greatly appreciated.

A few more information that I thought would be helpful.

The type of Music I listen to:

- Classic Rock
- Modern Rock
- Alternative Rock
- Indie Rock and a little indie Pop
- Trance
- House
- Electro
- Other electronic music

For now I have the Audio Technica A900. As much as I like my A900, I want something different, like the Denon D7000/5000, Sony SA 5000 or something like the Sennheiser HD650 or Beyer Dynamic DT880/990.

DAC: If you can use firewire then go with Echo. I have the AudioFire2 unit but I cannot use it at the moment as my latest notebook doesn't have firewire or expresscard. I'm going to upgrade to a different model soley to use the Echo AudioFire2.

I don't have any suggestions for the tube amps, I don't have any headphones that need them and IMO they use to much power for what the provide.
