Sorry for the delay. Taxes due, etc, etc. The amps I've used so far have been a Chord Mojo, NuForce icon hdp, Marantz HD-DAC1, Earmen Tr-amp, and twice now with my new Romi BX-2 Plus. I think the Romi has been the best of these but it's a little early to tell. Today I just received a topping D90 DAC that I found pre-owned. I'm thinking I would like to try to run that directly into the Romi amp. I don't have the balanced cable right now to go between the dac and amp. Plan to listen to my Dunu Zen balanced. I do already have the cables I would need to run single ended from dac to amp so I think I'll try that tomorrow. With the A-T's being single ended anyway I'm not sure that balanced setup would really help me with them anyway
