For the money this little DAC cost I think its one of if not the best $250 I have ever spent on a piece of stereo equipment. My only complaint was the range of the Bluetooth left something to be desired. It would cut out 15 feet away with good line of sight. BUMMER....
Well as it turns out there is a simple fix for this that I find hard to believe the factory didn't build it this way.
If you unscrew the BT antennae and look at the Brass elbow there is a setscrew like thing. Its actually a very thin cover that when opened reveals the solder connection for the antennae. An electrical radio friend of mine told me the optimum length for a BT antennae is 31mm based on the wavelength and the length it needs to be to resonate, thus making the most of the available signal. This one as it turns out is significantly shorter than that.
The fix is to slip the black plastic cover off the elbow revealing the existing antennae. Remove the elbow cover with a screwdriver and desolder the existing wire. Next measure out your new one FROM THE ELBOW WHERE THE WIRE BECOMES EXPOSED AND IS NO LONGER SHIELDED BY THE METAL. Y our total length of the wire will be a little longer than 31mm. Like 38-40 or so.
Cut it, solder it on and be sure to slip a piece of heatshrink over the wire so the wire and solder joint inside the elbow will not touch the elbow. Verfiy your 31mm length and put the black plastic cover back on.
And enjoy your SIGNIFICANTLY improved BT connection. Mine is a hell of alot better. I haven't measured it but it works great everywhere inside my house. Compared to previously its a huge improvement.
*I can not vouch that the 31mm length is indeed the optimum length but my friend is a pretty smart dude and mine worked great.
Enjoy.

Your friend is correct, the wavelength is around 125mm, the antenna is a 1/4wavelength so 125/4 = 31.25mm
Thank you for that. I know it made a hell of a difference. Night and day. Amazing that less than a half inch longer did all that. But I guess its the resonating thing. Either it works or it doesn't.
Hey Jeff..
Congrats on your D50s. How are you linking the sound?
I was using Musical Fidelity M1DAC until one channel died. I also got myself a D50s.
So far loving the D50s - as you said, best $250 spent.. amazing device.

Am I happy with my D50s? Like I said, for the money spent its amazing. You could add a zero to the end and be very hard pressed to top it. Or match it actually. IMO it really is a no brainer purchase. Also I am in the process of building a nice power supply for it so I should get a little more out of it yet.
Anyone on the fence about this , go ahead and pull the trigger. There is no way you will not love it. I am sure there is better out there but not in this kind of money.

Would love to get ur thoughts on the PSU build. I had also started a thread here to discuss the same..
