My vote goes to the K-1xe but I am biased by years of ownership. Could be a lifetime buy.

PLEASE match Advice Pass Labs X350.5 (20k) to Hovland HP-100 (2500ohms) Miss-match ???
GUYS / GALS NEED YOUR HELP 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*

Hovland HP-100 source impedance 2500ohms*

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?
Stereophile: Its input impedance was a usefully high 100k ohms in the midrange and bass, with just a small reduction to a still-high 86k ohms at 20kHz. Despite the claim that the HP-100 uses a cathode follower output stage, 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.

fsmithjack, I can only offer that I have used the K-1xe’s SE inputs from a tuner (and probably other things I have forgotten) and also the SE-only tape monitor input/output with no issues and found the sound quality to be excellent. I do recommend that you take advantage of the benefits of the Ayre’s true-differentially balanced XLR inputs from your most excellent DAC as soon as you can swing it financially, but you clearly already get that.

Another great post, Al. fsmithjack, the review below accurately articulates my long-term ownership experience with the K-1xe: http://www.soundstage.com/revequip/ayre_k1xe_v1xe_followup.htm Note the line: "You won’t mistake and K-1xe and V-1xe for tubes, but you won’t care either." Pretty much sums it up IMO. Also notice the reviewers emphasis on the K-1xe’s compatibility with a wide variety of amplifiers... If you do get the K-1xe and plan to use it via its SE outputs vs balanced XLR, take heed to the manual re: that it inverts polarity via the SE outputs, so simply reverse the positive and negative speaker cables on both right and left amplifier outputs to correct.
