GUYS / GALS NEED YOUR ADVICE PLEASE!
A friend said this preamp is outstanding and will sound great with Pass Labs amps and to not get caught up in the specs but the measurements say different.
Pass Labs X350.5 amplifier with input Impedance 30k ohms Balanced or 20k ohms Single ended*

Guys / Gals, can I used my Pass Labs X350.5 amp with Hovland HP-100 preamp? Has anyone used Pass amps with Hovland pre's. I will be using Magico S5 Speakers and Bricasti M1SE DAC but want it to sound the best it can. Should I just stick with the Aesthetix Calypso pre I was leaning toward before my gut said to go for the Hovland HP-100
Hovland HP-100 Preamplifier: * Output impedance: approximately 2500 ohms or according to Atkinson, Hovland HP-100 (2500ohms) its source impedance was high at 2.4k ohms, rising to 4.3k ohms at 20Hz. The partnering power amplifier would best have an input impedance of at least 47k ohms if the bass is not to sound lean*. The Pass Labs doesn't meet the x10 requirement it is supposed to but it is sort of close when looking at it. What do you guys think? I am not sure what to do but you guys will know what to do?
I posted in the preamp section but wanted to ask you guys also as many know the Magico speakers and they say the sealed box bass can sound a bit lean so don't want to add to it with impedance mismatch with pre and amp but also the numbers are not terrible so maybe you guys can give me some advice?
Thanks
