I don't think the Lyr2 can run without tubes installed since the tubes are part of the preamp section.
Yes you can change the sound of the Lyr2 by changing tubes (this can get expensive fast).
If you get to the point where you are changing tubes often I suggest getting these; http://www.tubemonger.com/NOVIB_Socket_Saver_1960s_NOS_British_McMurdo_B9A_p/novib-mcmurdo.htm
*Your DAC is very good, I would not upgrade your DAC at this time. For one thing, your sound card has features that your DAC choices will not have, and you may not want to give that up yet. Frankly, I think DAC upgrade was only a "10%" boost in SQ - NOT night and day. I have a realtek set with ELNA caps and I think it is pretty black (no noise I can detect), but I haven't tested this much as I love my ODAC.
*None of your choices make a ton of sense if you are just looking for a good amp section, they are pricey and include DACs. Also some are not particularly powerful. Don't bother going portable if the amp isn't going anywhere!
*Going Solid State will provide you with low cost good sound and you won't have to worry about replacing tubes. Unless you are convinced that only Tubes will do ya', I'd save a lot of money and stick to solid state amps. The "treble" is going to be OK, just not rolled off (sounds like it is for you presently).
*Schiit Magni if you like Schiit's stuff - JDS Labs O2 if you want an amp I know sounds awesome with my computer on-board sound / ODAC. Either are around $100 bucks + cables or, in the case of the O2, ($130 + AC adapter + Customizations if you want them). And yes the O2 is technically portable, but I don't really use mine that way.
The Project Ember thing is interesting, but $300+ C'mon. I used to pay about $1/watt for premium car audio amps back in the day but these things are powering by the mW (1/1000th of a watt)! I just can't spend big on headphone amps yet but that's just me maybe.
Also - Pay attention to specs! The HE-400s are about 50 Ohms, and most newish headphones are pretty low impedance. Unless you KNOW you are going to buy headphones @300ohm or 600 ohm someday, pay attention to the power output at lower impedances. Vali gave you about 1 a watt @ 50 ohms, the vahalla 360 mW. Lyr2 is 8w - total overkill IMO (though too much power not a bad thing).
Thanks for all the help everyone your awesome.
Ah I thought hybrid amps would allow you to use the tubes to essentially color the sound while keeping being able to use the solid state amp with out the tubes to get a solid state sound. (stupid me should have read more before making assumptions, thanks).
I was reading more about the Lyr2 and Asgard2, but it seems that in order to get the most out of the Lyr I would need to change the stock tubes as well, and given its current price I wont be able to spend again on it, so i think I'll stick with the Asgard2, which still seems great at a far lower price, so I'll have some money saved for my next headphone upgrade in the future. (and still safe around the kids so the tubes don't get broken as they probably would on any exposed tube in my house lol).
Thanks every one I learned allot from this thread and all the great people here.
and thanks for keeping, with my decisiveness and all the questions.
