As today a power peak killed one of the channels of my my LUA4545L( … /4545l.pdf) i had to improvise a interim solution until my tube amp gets back from repair.
I had a SMSL -SA 50 ( … B008XTDBYW) in my office driving two smaller speakers.
So i connected the SMSL-SA50 to my volumio raspi, a O2 Objective DAC and my Teufel MK40 II speakers.
And: Wow ! I am totally impressed by the sound it produces !
It is really worth running it with volumio and high end speaker boxes.
