Jolida Glass FX Tube DAC III

jolida-fxtubedaciii_black

While very affordable, especially for a tube DAC that can possibly give some warmth or indeed, an analog sound/feel to CDs and digital media. I have one concern and that is the very short warranty on something of this nature. The Jolida Glass FX Tube DAC III has an unusually short warranty of only 6 months limited parts and labor with 3 months on the tubes (3 months for tubes makes sense though). This is unusually stingy in the industry. There are no details about build and such on the manufacture site, save the specs which I listed below.
