I got the new 'M' version of the Astell & Kern sp3000... it's a more mobile smaller/lighter DAP.
the original sp3000 was solid Stainless Steel and extremely heavy and slightly unwieldy to the point where it could literally be used as a weapon... this 'M' DAP is much lighter and physically smaller... made of Aluminum.
it has the same specs...
