Teajay, the Linear Tube Audio's MicroZOTL does not have balanced inputs outputs, and from what I know, pass amps sound better thru balanced inputs. So your combo of MicroZOTL and XA-60.8 or X250.8 sounded better using RCA inputs than other
pre-amps (including pass XP-20) with these pass amps even using the XLR inputs/outputs? I am trying to get best pre-amp (without spending fortune) for my new coming X-350.8 amp. I would go with XP-20 but it has 2 units and with huge X-350.8 it will take a lot of space that I may not have.
Thanks.
