nobody can agree on that
I have an E10K myself, also a Topping D10, D10B, an O2 amp and a Singxer SA-1 (which I mostly see as a big heavy glorified knob - having a lot of volume headroom is nice I guess but hard to justify)
I also returned a lot of DACs between the $400 and $700 mark because they weren't doing anything audibly different to the sound unlike what old people on head-fi were claiming
my advice would be to focus on headphones and only consider replacing stuff if you very clearly need more juice
