Parasound Preamp

I had that amp for 4 weeks - then sold at a big loss.  Awful phono pre, some of the knobs are very small - if you have big hands.  It will sound better that a marantz or demon.  Be warned that the warranty is not transferable - always a big red flag for me.  Rogue has some nice pre’s that are reasonably priced.  I have settled in on ARC.

I picked up an “Open box” deal awhile back. It’s a really nice pre, with good connectivity, and a descent DAC also. Very quiet background, nice remote and HT bypass. 
I have a Rel sub and have tested the sub-out with a longer balanced cable with impedance matching transformer at the sub end. Works like a champ, but I still prefer the Rel “high level” input. 
Any specific questions about this model?

I have this preamp and use it with the Halo A21+.  I am very pleased with it.  The DAC is pretty good, although I use a separate Denafrips DAC.  The phono preamp is also good.  I do not use the subwoofer output. I use REL subwoofers and speaker outputs to the subwoofer.

First look at the picture of inside of that preamp don’t give me any optimism.
