“ Top ratings for this small, cute and very well priced DAC. My sound comparison is with a Musical Fidelity V-DAC and the Fubar2 has more detail, dynamic and greater clarity. It can be easily upgraded with a change of the opamp and the addition of a power supply unit called The Supplier at $144. It is beautifully made and some of the older versions have a cute comedy dog logo on the...” --Prog Rock Man

“See my full review HERE. In summary, this is a well rounded, high performance amp that really offers a lot for the price. It's neutral, clear, and balanced - literally speaking and in terms of sound. Not sure why it isn't more well known. ” --project86
