I had a good look at the circuit board of the Wyrd. Seems a good desgn and uses the age old uA723 as voltage reference for the 5 V output taken out of a 2A series power transistor.
The rectified first stage 11V dc output has two 2200 uF caps but no bypass. Same with the final 5V output which is also quite heavily filtered.
I added two 0.1uF PPS caps to the first stage caps and to the 5V output of the usb output to see if there is any sonic difference. The choice of caps is simply due to size, availability and good dielectric property.
Presto, the Wyrd retains its 'lively' presentation but sound is more controlled and civil in the way that the iFi usb power is. Very worthwhile additions. There is also more details across the spectrum.
I recommend that anyone with a Wyrd should try this simple mod.
