You can demo Chord at Dubai Audio - indeed I am doing a couple of events there on the 20th and 21st of this month. As to measurements - it depends what you measure. SINAD and distortion are very simple tests and do not tell you how it sounds like at all. The ear/brain is extremely sensitive to vanishingly small errors, and these matter a great deal to the ability to enjoy music. At the end of the day you need to hear it for yourself - only you can decide with your set-up whether it works for you or not.
