Yeah I have heard lots about the FUBAR. Lots of people like it and it seems super well priced. It really depends on what youre going to use it for though. I mean if youre using it portably you have to make sure you have something with an usb out, which is super rare for a portable player. If youre using it in your home stereo you face the problem of the fact that the signal from your DAC is going to be amplified by its internal headphone amp and wont sound very good if you hook it up to your stereo. Again, the key factor to whether its good for YOU(we know it is relatively good). And to know this I would have to know how you would be using it.
wrt DAC's in general, I am deciding if i want to sell my headroom microdac and buy the new headroom product:
HEADROOM ULTRA MICRO DAC. I would sell my microdac for like 250 and buy the ultra micro for 699. At this point, totally not worth it IMO, but if it drops to 500 I am jumping on that motha. I have already heard from many that its the best DAC under 1500, and I believe it, Headroom is an amazing company.
