I'd say the same for all components including the DAC chip because humans can't tell the difference.
But since you think it makes a difference you may as well think the Op-Amps in the DAC makes a difference too.
BTW, I'll be getting my Graham Slee Solo back tomorrow then I'll sell it.
I first got it when my friend upgraded to Graham Slee Solo Ultra Linear and gave me the Solo as a gift.
Then I borrowed it to another friend.....
1.x years later (now) and he stopped being an audiophile so I'm getting it back.
You want an English lesson?
I pm'd feiao about possibly helping with Chinese to English translations of press releases. He asked me about price (when I expected to volunteer) so after discussing with a professional translator I made what I think was a generous offer. Haven't received a reply for a day. Was my price too high? Or do I not have what it takes to work on the English language anymore? I guess it's not the latter if what I write is still sophisticated enough to trip over an international school student
