Separate names with a comma.
I like "B." I also like the mechanical volume pot.
OPTION A FTW!!!!
I'm kidding! I like option B.
thanks, I believe we already have answer. thx for everyone.
Thanks for stopping the madness, James
the original ESS9018 has 135 SNR
the ESS9018k2m has 127 SNR ...
so please put in the original ESS9018 !! that would rock!!
I currently have a Fiio E18 and I can't wait to upgrade to the Q5. I know whatever Fiio puts out will be HQ.
It is too early to talk the ETA of Q5, but it may take 10 months to develop it.
Hm, I wonder if this difference in 8 SNR will be audible to smb
Fiio, leave Sabre aside already and go with PCM 1702/1704
Sorry, the original ES9018 has 135 SNR for mono, not stereo....
So? 8 * 2 == 16. Do you still believe you will hear the difference?
I don't know why you're so eager about SNR numbers, but I believe an implementation plays higher role. And your ears - everything else doesn't matter
You guys should ditch the pure delta-sigma DAC chips and implement something like the Advanced Segment architecture chips from T.I.
Anyway, any official word yet on just how much output power the amp-module in this and the X7 will have? Like, how much output into 32 ohms, or 300 ohms? ANd what the output-impedance will be?
FiiO already uses the TI PCM1792A in the X5 and X5ii. The DAC chip is still all Delta-Sigma but with a multi level design to better deal with inherent noise from Delta-Sigma. Many DAC chips use a similar approach, and 'Advanced Segment' is just TI's name for the multi level D-S implementation they use.
From the PCM1792A white paper pdf:
So then is there ANYTHING out there with a R-2R architecture, or at least partially R-2R architecture, that could be utilized in something like the Q5 or the X7?
Sure, but it would be expensive and inherently large.
