Ayre is super easy to get hold of. Very responsive bunch. I think you should buy the Topping and do a shootout! Where is the Topping made?
Replace Ayre Codex with Topping D90 DAC
My Ayre Codex takes USB from an ultraRendu and sends balanced analog to an Ayre A7e integrated that drives KEF LS50s. The sound level has become nearly inaudible, and I suspect it's a problem with the Codex -- substituting a microRendu made no difference; the sound level with the Ayre C-5xeMP disc player is fine. Should I send the Codex to Ayre for service or buy a Topping D90? Anyone hear the two DACs?
