Machine, I can't help but think that the Parasound JC-1's and the Conrad-Johnson Premier 140 are two very different beasts. BTW, the Parasound offers balanced inputs and no C-J offers balanced inputs or outputs. While it will probably work, the 850 Ohm out put of the 17LS may restrict amp choices. Some how I thought you prefered a ss pre. Good luck on what ever you choose.
amp-preamp considerations.
what are technical concerns[matching]when mating.have c-j prem.140 and am lookink for pre-amp.considering pass-lab x-1 or simaudio p-5.not stuck on either.using adcom gfp-750.looking for improvment on this.also new to tubes,think i would prefer ss.this amp is like having a small heater in da house.any input appreciated.
