Suggestions on Integrated Amp./Seperates to Run my Klipschorns

On that list...the PrimaLuna.  I can't imagine running klipschorns with the SS gear listed as I would expect it to be very bright.  You need 3w of power to drive those speakers to deafening levels.  They have 105dB SPL.

I would recommend a SET.  Either 300B, PX25, PX4 or 2A3.  My hunch is the stuff that I import (Art Audio) is a bit above your budget (my least expensive option is $12,500 as an integrated) but other SETs or a used SET would be a wonderful option.  

An alternate would be First Watt with a Pass labs preamp if you want SS.  First Watt J2 would be brilliant.  Maybe a used X-1?

Art Audio gear is spectacular with Klipsch speakers.  My personal taste runs to the PX25 over the 300B but we would want to talk about exactly what you like in terms of sound profile as you could also consider an EL34 Push-Pull.  Each is a little different and will give you a different sound profile.  

You may want a DAC depending on exactly what streamer you go with.  A very interesting choice would be the Chord Hugo 2 with a 2Go streamer.  Most of these low powered amps are not fully balanced and you won't get the full benefit of something like a Lumin D2 with them.  The Chord is an amazing DAC and the 2Go streamer interfaces with Tidal and you can easily add your own music library to the device. 

If you have any interest in this idea, PM me and we can talk about a bundle.
