Astell & Kern sp2000 or the sp2000t


Any experience or opinions on which is the better DAP to buy. I like the flexibility of the sp2000t with the 3 amp selection. However I thought the 256k on board storage would be enough but its not.

Most important is the sound…does the sp2000t trade off flexibility and price for sound. I read the sp2000 has better chip set?

any thoughts, not sure if I should return my sp2000t for the sp2000? Better sound, more storage, less flexibility?
