I know that the JA80 is better than the DA88S ...BUT you will need the matching preamp for your amp if you take the JA route - I tried to run a JA50 directly from the variable DAC output and it is just not the same....
The DA88 is a hell of an Integrated amp - I own the DA50S and is great too.
Hope this helps,
