To be honest, I am just beginning with my sort of hi-fi needs; but I presume an amp would also be needed...nothing TOO strong but should cover both headphone and normal speaker needs. That is why I thought of the Nuforce HDP...anything better?
You do realize that of all the parts you'd need in a sound system the DAC i the least important and has the least effect of sound quality.
The single most important part is the speakers and the room itself.
Before anyone can recommend a DAC they would have to know what is the souurce material. Is it pre-recored CDs. MP3 files or something you recorded yourself. There is no need ofr a DAC that can handle 192K at 24 bits if you are listening to an MP3 or even a CD.
