Can a DAC sort out a flat\cold amp?

I know this amp is my problem but  i can’t just buy another 3k amp. currently my biggest problem is the bass , i’ll worry about noise later. I really don’t know what so you mean by chinese dac. Can you give an example?

buying another amp or seperates are out of the question. When i plug in my dj controller & tweak the sound mid,hi,low it sound good enough for me. Is there a way to get an eq on thouse chinese dacs?

as for the speakers they are not to blame since they sound good with my old amp which was a pioneer home theater 100w. Long story short i just need a cheap fix until i’ll manage to find a replacement. Cables did not help. Even buying a warmer speaker might not do the trick since this amp is not so easy to pair with speakers. 

Buy a Shitt Loki EQ. It used to be about $130, but I haven’t looked lately.

Like @jasonbourne52 , I doubt it is the amp. I have heard this amp and it didn't sound bad to me. Aamof Bill Watkins used that amp to demo the Gen 4 speakers which go down to 41 hz. There was no doubt that they hit the 41hz.. I suspect something else or an incompatibility issue 

there's something wrong, but truly should not be that amp unless it is defective.

to isolate the amp: skip the pc, make a simple direct path: a cd player directly to the yamaha to your speakers. a few familiar cds. 

great? lousy? then the amp is defective, who sold it to you?
