I went from Stock Opa2604 to the dual LT1028 and I ran into a bit of a problem. The dual op amp is sitting too high so I couldn't get the case to fit.
I plugged it in anyway.. Hmm. A bit on the bright side. Not feeling it. Then I tried the 2nd chip. The AD8273N.
Booya. WOW. This chip makes this little unit sound too good not to keep that chip in there. So even without trying out the 3rd. This chip will stay in here. This sound I am hearing went from good to...... My best sounding dac? Lol.. It has to be. I am amazed just how much this jives with the stock AD1852 DAC chip. Shocking..It simply sounds too good to be true. Lol. Now onto the Fire Phoenix.
DS, i am playing with cheap Amp. Lepai Thripath TA2020A, made in china but is sounds very good for only $20 bucks, using it for my TV using 2 Daytons B652 Speakers, cheap and fun setup. This Cheap Amp is using the SAME opamp the FirePhoenix is using, so it should sound even better with an upgrade on OpAmps.
i changed the OpAmps on my Lepai and i am using NES5532P, sounds better. funny thing is that i didnt even remebered/considered the Fire Phoenix, its using a pair of cheap OpAmps so i am gonna buy:
LT1028, LM4562 and OPA2134P and let you know.
Where did you bought your OpAmps? ebay? seller? i am worried about counterfits
