Best mid priced Amp-Preamp

+1 on the Hegel H160. Also look @ Peachtree and Schitt.

  Please suggest best amp-preamp under $2000 for my KEF 103/3 reference series speakers.

A little more but this new John Curl designed Halo Integrated just got good raps put on it, not quite as as powerful as the older one which you could get on your budget, has everything even a Sabre dac in it. And would love your speakers.
JA's bech tests yet to come.

+1 with tomcarr,
The Freya preamp is pretty darn good for the cost and it leaves you enough for a Vincent, Adcom or Schitt amps/amps.

All the best.

I’d go along with that too curiousjim , a Schiit Freya (great switchable tube/ss/ or passive preamp) with a Schiit 100w Vidar. Should work a treat with the KEF 103/3, and at 93db maybe the Schiit Aegir 25w class-a if he doesn't want party levels, that would sound sooooooo sweet.
And the OP kns54 can trial them for 15 days

Marantz pm14s1 integrated, if you can still buy one, getting hard to find brand new. A second for the rogue sphinx v2...on the more economical side, the new marantz pm8006 is a nice amp as well at only 1200.
