I did browse this companies products at one point. I think the price differential is significantly more than you mentioned, and I think the "audiophile" power supply that is required to power their mini PCs are sold separately and can be pricy as well. IIRC players include "audiophile grade" USB modules that are said to be better sounding than the mass produced stuff, but I cant offer any first hand knowledge about that, whether it be real or hype. The processors in the lower priced players were low powered and fanless, which is good and bad. No fan noise, but limited processing power as well, and not at all comparable to the processing power of an i5 or i7 NUC at a similar price point. OS were Android based on some products. If you are thinking of using the JRiver DSP functions or anything similar, a low power processor will run out of steam pretty quickly. I've had experience with JRiver not being able play multichannel high res files with a low powered processor, but that may have been specific to my setup. I came away with the opinion that most of their products were mainly stereo centric, but that may only apply to their DAC products. But by all means, check it out. A lot of it has been reviewed on the
Computer Audiophile site.
