I’m doing something which I can’t really afford, but doing it anyway … I’m upgrading my Stereo … I like music, and believe it should be played at the highest affordable quality.
So after getting a new Stereo Amp (Creek Evolution 50A), I got a new Phono Amp. and then started looking for a DAC … and after reading I do not know how many posts I decided to get an S.M.S.L M8 (from Amazon fro €249.99), not too expensive and according to what I can read very good.
So I got it hooked it up to my amp, connected my Notebook (Macbook Air 11″ / 2011) using USB … sounded nice, then my Macbook Pro Retina with digital (fiber) in some way better than USB, slightly more air and openness. Then decided to use my old Apple Airport Express (MB321LL/A – 802.11n version 1) using it’s digital output (I don’t like the build in DAC – it’s a bit too dark for me), and this is where I started having doubts about my buy.
There was drop out, all the time. Right I changed, to direct WIFI; same, I change to a newer model (the square one which I also have), same jitter, ever 1-2 seconds a drop out.
I asked on head-fi.org and someone after a few days suggested that I should try to reduce the jitter on the Airport Express … and after a a couple of hours I found this thread/post on the Apple Support forums, suggesting that it’s firmware problem, and that the solution is to downgrade to firmware 7.6.1.
See that could be a problem, as finding it as a download is not that easy, but I was in luck it’s possible to do it directly from the AirPort Utility (click on the version while holding down ‘option’), and select 7.6.1 … wait … reboot … and it works.
With the square Airport Express (802.11n version 2) it’s not possible to downgrade to 7.6.1 (I only see 7.6.2), there is a bit more information here:
But I have not been able to figure out what version the square is … if someone know please let me know.
So, jitter is a problem for all firmware’s after 7.6.1 …
