A plea to the community: Would someone out there with access to some lab-grade test gear and a true reference DAC perform a legitimate head-to-head among JPlay and the other music players? I will admit that I am a JPlay believer (please don't hate). And I am bothered that there seems to be no measurable proof of its effectiveness. (And please spare me the speech about how something does not need to be measurable to be significant.) I have read some very thoughtful and clever experiments posted online that ultimately cannot demonstrate a measurable difference between, for instance, JPlay and JRiver. But I am left unconvinced because the test gear itself always seems inadequate. The last one I read was a very well-designed experiment with a write up from a guy who was obviously very smart, but the measurements were captured using a PC sound card with a specified -89dB noise floor on its ADC. Don't get me wrong, I realize this is a pretty tall order. Assuming a difference does actually exist, I would expect capturing that difference would require a system with incredible resolution and repeatability. But I have read online reviews from individual contributors that featured extremely expensive gear from Audio Precision, Rohde & Schwarz... my assumption is they had access to these assets at work (which is awesome). So, would someone with one of these $100k analyzers sitting around the office sneak a reference DAC into their lab and perform a rigorous after-hours experiment just to satisfy the curiosity of the audio community? If your boss catches you, you are welcome to throw "a2x024" under the bus...
