To bring this thread back from the dead, Just had my Sonic 305 (rebadged ULN - 8 ) back for a repair and mod and the service from Jon Stern at Metric Halo could not have been better.
They do a mod to the DI input to better it as a phono pre amp. They also did a refresh of the caps on my mic pre board as they were getting a bit noisy after 4 years of pretty much continuous use. This unit as a DAC - Phono Pre _ pre amp ( I go direct into Genelec 8050's is truly superb.
Now time to get stepping on more needle drops
