This dude compared some of the hypetrain CHIFIs of different price ranges in this post:

He has the LZ A6 and T800 at the top of his rankings. Really deserves a Nobel prize for his contributions to CHIFI and Headfi!
I've kept the LZ A6 in my AE wishlist for the longest time, but the lowest I've ever seen it go is $230ish USD, which is not as low as the upcoming 11/11 prices. I'm very happy with the T800, so no push factor for me to pump money for the LZ A6, though it has tuning filters as a plus.
Though this dude and a few folks I asked said the LZ A6 treble may be a bit sibilant and harsher than the T800. I already found the stock T800 at the very border between harshness and brightness for me, so that's a bit of a turn off for me.
There's headfiers that say the LZ A6 mini, (which is much cheaper, has no gain switch and a lesser drivers, and comes with lesser "non essential" filters), is somewhat similar to the LZ A6. U can possibly ask them in the CHIFI thread.
