Thank you for your offer to review my DAC, but I would decline. If you want to evaluate the DAC you'll have to buy one like everyone else. As yyzsantabarbara comments it comes with a 30 day return privilege. Who knows, that may cost you less than the round trip of mine. Yes, the gentleman who rated the Musetec above the Mola-Mola Tambaqui makes cables, but he also makes the respected Eno Ethernet Filters. He is quite knowledgeable when it comes to a DAC's place in a system.
Now I remember my comment about the Sonnet; actually it was not about the Sonnet. My point was simply about the value of an accommodation purchase by the Stereophile reviewer and the A+ category there. IMO, not much value. So I looked at the Sonnet. Seems you "owned" it for less than a month. Really? Not much good hardware there IMO. More expensive than the Holo Spring 3, but the Spring shows a far better insides than the Sonnet. As between the two I would choose the Spring. That is explained by its European manufacture; they simply can't do it. And, of course nothing inside approaches the Musetec.
