Metrum is in a completely different league than Rega. HiFi Critic awarded metrum with 170 points, and Rega with ... just 50. That should give you an idea about the diferences we are discussing here.
One word of advice though - the Metrim is very sensitive to signal jitter. Buy only if you can afford to buy an Audiophileo 2 USB->SPDIF converter ($579) to go with it. Cheaper converters, like MF V-Link, Stello U3, HiFace 2/Evo, Halide etc will not do it (yes, I have tested them all with Metrum and then some).
Coupled with Audiophileo, Metrum is absolutely stunning piece of gear. You can pay 10x more and get lesser sound.
