No they will not go good together. Read this off of Schiit's website:

Can Valhalla drive my orthodynamic headphones?
Being polite: not a chance. Although Valhalla can deliver large voltages into high-impedance headphones, it cannot supply the current needed for low-efficiency, low-impedance orthodynamic headphones. If you have Audeze or HiFiMan headphones, look at Lyr. LCD-2s, HE-400s, and HE-500s are also efficient enough to be used with Asgard, if you’d like an all-solid-state option.

So if you want to use Orthodynamics, consider LYR, and honestly there are headphones that are great under $1000. Personally everyone I know loves the 

Koss ESP-950

It even comes with its own amplifier! 

Also take a look at Hifiman HE-400, HE-500 etc. The fact that you thought you could use a OTL amp with a LCD-2 tells me you haven't been at the mid fi audio yet. Therefore instead of dropping lots of money there are better choices for you. Later on when you have the funds for a $1000 headphone and a equally as good amp then buy the LCD-2. Remember its best to spend $300 on headphones $600 on amp and $100-$300 on DAC. The amp is going to affect the sound a lot. 

Look at this analogy:

For example:

(This represents Beyerdynamic T1/LCD-2 with a "decent/barely capable amp and no external DAC)

Would you like to have a ferrari but have to drive it at 20 miles per hour, use basic unleaded gas, and drive down dirt roads. 

OR

(This represents HD650/HE-400 with a great amp and DAC)

Would you like to have a Honda Civic and drive it at 90 miles per hour, use super unleaded gas, and drive down highways, tunnels and anywhere else? You choose. 

I would pick option 2 IMO. You could always upgrade amp and dac later on then sell your headphones and pickup LCD-2 used.....(HE-500 is even cheaper used).

Ok, buy a better DAC. HRT Music Streamer II is $100 used and is amazing for the price. That Chinese amp thing you were looking at is probably going to be a POS. Here are 5 budget DACs:

HRT Music Streamer II - $149 new - $100 used

ODAC - $139 - $90 if you build it yourself

Musical Fidelity V DAC - $349

Schiit Bifrost - $349

The Lyr amp will work very well with LCD-2, in fact its a great combo. Do look at HE-600/HE-6/HE-5LE those 3 are great too, but if you already made up your mind on the LCD-2 then get the Lyr, and a good DAC then you'll be set for life.

The HE-6 and HE500 and HE-5LE are all great. The HE-6 will sound better according to tvrboy the HE-6 is better than LCD-2. Take a look at this:

Once you finish reading the above post, I think you'll have made up your mind . The HE-6 is a really nice headphone, I own the HE-400 and soon the HE-500 and can say its fantastic. The Lyr will push out more than enough power for the HE-500 which is a power hungry monster. The LCD-2 is good too, but the prettier headphone is not the better one, you know what they say; Aesthetics vs Accuracy or Power vs Pretty. You get the idea :D. 

But.....DO NOT SKIP OUT ON A DAC! IT WILL CLEAN UP SOUND AND WILL MAKE A LARGE IMPROVEMENT IN SOUND! Koss ESP-950 are great because you get the amp included and just have to buy a DAC. Look at the budget DAC's its better than nothing. The DAC I posted (a few hours ago) are all great choices under $399.

I can't speak to the HE6 as I haven't heard it. Neither has Vampire5003 apparently and I don't think you should base your decisions on anybody's post or link to a post. I have heard the LCD2 with the Lyr and it sounded excellent, I personally preferred and therefore purchased the HE-500. I do agree however that a decent DAC is essential as the impact on the sound is significant and since you are considering the Lyr the Bifrost seems like a natural fit. I have yet to hear it myself but did just order one yesterday. 

There are so many opinions out there and I could cut and paste any number of reviews/impressions that will directly contradict each other so take that for what it's worth. Look for a head-fi member who seems to listen to similar music to you, has a similar budget to you and has reviews/impressions of other gear that seem to jive with your own and use that for a start. If possible then audition them for yourself and trust your own ears. 

In short..The Lyr has plenty of power for any of the orthodynamics (although some think the HE6 benefits from even more power) and is a great bang for your buck.

IMO skip the Koss, very ho hum. The other headphones you are considering are much more fun to listen to and if you have the money you won't regret it. The Koss is a sidegrade or even downgrade from what you already own.

I currently own the LCD-2.2 and the Lyr, and will say that it is an excellent combo.  I also had the opportunity to demo the HE-500 and HE-6 on my Lyr for a 2 week period, and very much preferred the LCD-2.2 over both.  In my opinion, the HE-500 had a very bloated mid-bass.  Coming from the HD650s, I did not find this to be a welcome change, as the HD650s already have an exagerated bass.  To my ears, the HE-500s just weren't that exciting.  I tried hard to like them, but I just couldn't.  The HE-6 on the other hand were more refined, but it won't matter what I say, because people will jump in and say that you have to hear them with a speaker amp to hear them driven fully.  But for the purposes of driving headphones with only the Lyr, I'd take the LCD-2.2 over both the HE-500 and HE-6 any day.  The sound is very fluid, but tight at the same time.  Very music and engaging.  I wil say that my HD650 produce a wider soundstage, but other than that, I prefer the LCD-2.2 over them for everything else.

The LCD-2 and Lyr is a very good combo. The HE-6 and Lyr is less than ideal. While being adequately powered, the HE-6 is smeared and etched.

The HE-6 properly amped is much better than both LCD-2 and HE-500. You could argue LCD-3 and HE-6 are very close, but 

IMO, short of Stax no ortho, nor dynamic really touches the HE-6.

The HD-650 is much less exciting than both the LCD-2 and HE-500. Has sub-par bass with the exception of a mid-bass hump.

The HE-500 is very similar to LCD-2. Boast much smoother mids, but less impactful bass. Between these two, it's not a matter of which is better,

but which is preferred. 

Each of these headphones were very livable with the Lyr. the LCD-2 was excellent and most preferred.

I too have a Lyr and LCD-2 combination and am very pleased with the performance and sound.
