New DAC to replace bel canto dac 2

I am using a dac 2 between a olive musica and Sophia el34 integrated. My speakers are Merlin vsm-mm with all JPS superconductor cables excpet for a stereovox digital to between the digital section. I have a problem of signal dropout often which is quite annoying. I've changed digital cables with no improvement. I believe it is the dac2 which is extremely sensitive to signal input. I've spoken with the bel canto folks and they acknowledge this is probably so and doubt any faulty equipment. My question is what other dac's do you folks recommend?
