Not made in the USA, the musical fidelity lowly v90 dac @ only $299.... by keeping with USA only, your missing out on a bargain of a dac. Read what Stereophile had to say about it at the bottom of my reply....I recommend it often for a reason, because it just sounds damn good. No reason to spend thousands. All just my opinion. For a USA dac, ok fine, the Border Patrol is a nice one, if you can give up on the need for optical ( it only comes with spdif coax). Also, the Jolida, or now known as Black Ice is also a nice dac. however, I do believe the final assembly is in CHINA...if that is bothersome. I own the jolida glass dac 3. Here’s the review for that one...

*But from my own listening and my comparisons with the outstanding Auralic Vega and my workhorse Benchmark DAC1, I think the V90-DAC belongs in high Class B or even low Class A of "Recommended Components"—no disgrace for a digital processor priced at just $299.—John Atkinson*
