I have something special in store, wont be here for a couple of weeks, amazing OPAMPs that is. wont say more until they arrive, sorry about the cloak and dagger
stay tuned, this has the potential to be a MASSIVE WIN for D10 users
Hi qusp, just wondering if you got the new OPAMPs and if they made the massive improvement you thought they might?
I have just been doing some A/B testing of my D10 with optical and USB inputs. I thought it would be very unfair because although I'm using the same phones - IE8's - I'm using different sources.
My portable rig is the optical source, coming from an SD card in an Edirol R-09 recording device, with 16bit/44.1kHz .wav files ripped from CD using the uLilith audio player on my computer. The USB comes direct from my custom music PC, again using uLilith but just as an audio player-to-USB. I've been swapping the source every 30-60seconds while keeping my IE8's firmly in place in my ears, and I have to say I'm really surprised. The R-09 may not be a dedicated audio player but the sound quality from its optical output through the D10 is instantly noticeable as cleaner and clearer right across the spectrum than the USB + D10 route direct from the computer - despite the fact that the music in both sources came from the same original CD ripped using the same audio player in my computer! That's why I thought it would be a very unfair test, as I assumed that the R-09 adds extra components into the signal path and so should be inferior. I guess the conclusion must be that the files are reaching the D10 as 16bit/44.1kHz .wav files and the D10 is simply better at processing the optical source than the USB source.
