Any alternatives to Astell & Kern DAP's?


I'm looking at the A&K AK 100 -2 but at $900 (cheapest I could find on the internet) it caused me to pause. Is there any alternative that would be less expensive? The Ibasso DX90 is something I would consider but the reviews I've read are mixed. Would appreciate any feedback you could give me. thanks.

I'm leaning towards a fiio x5 which supposedly supports24 bit /192. It can be had for about $300 new or $250 used.....stay tuned.
PONO. Just ordered one with the balanced cable for my enn 650. cant wait. planes will be fun again.
Fiio X5 and the Hifiman units are worth contenders. headfi has tons of reviews and detailed threads on them and related topics.
