HIFI PLUS Review:Golden Reference DAC/Pre-Amp/Headphone AMP System Part 2


by Alan Sircom | Nov 21, 2016 HiFi Plus 

The best thing about this Questyle quartet is they all go after the same goal of neutrality and accuracy; the performance of one goes with and builds upon the performance of the others, and there’s a sense that is you start with any one device, the others will logically follow. If you have a pair of headphones good enough to warrant a CMA800R, they are good enough to benefit from balanced drive, in which case two CMA800Rs are the logical choice, and that means a CMA800P is the logical choice in driving them, and the DAC is the obvious model to deliver the best signal to that trio. Or, you start with the DAC for its sheer fidelity, then add a CMA800R and go down that route. Or even, you have a Stax energiser and want to hear what its capable of, and wind up with a CAS192D and a CMA800P. And when you compare the gold standard with the regular versions, you’ll probably go for gold at each step along the way. Every way you slice this up, all roads lead to a couple of gold Questyle boxes or more. I’m not saying this is all you ever need in headphone replay because I like to keep in employment and there’s always the option for the next thing to sound even better, but if those Editor powers wore off tomorrow and I wanted the best in headphone replay, I’d have a little pile of gold bricks next to my computer…
