im going to buy the fiio E11 amp, but I still need a dac. Im looking for a dac that can take a mini toslink 3.5mm input.. but I would also like to be able to have a 3.5mm digital input. I know that the E17 has this capability, but like I said, I would like a separate amp and dac.
Separate amp is easy.
Separate DAC... is going to be costly. Haven't seen too many of these that are inexpensive.
There is an advantage to having dedicated DAC/AMP in that you can get overall better sound quality (debatable, and depends on how sensitive your ears are to changes... so you may or may not feel/hear it) but generally speaking that's in the case of higher end models which can cost you A LOT.
Unless you go the DIY way.
