I dont see what good that will do. The KSA150 is 47k in so the min load is
9.7k, adding 20k to the Krell only brings it to 10.3k and reduces my max
levels by about 30%. Seems like a heavy penalty to increase input impedance
by 600 ohms.

The net effect is raising the load impedance of the player.
I've experienced this before.
It'll cost you 3 db of gain, but may well sound better.

Though any CD player's output is regared to be able to drive low
impedances, in some cases they can't do it just right.
A higher load value may bring back the good sound.

Hey Graham, Sander says Brits put cheesy output drivers in their CD's

Not only Brits, but all brands with opamps at the outputs.
In fact, Sony even recommends loading their players with over 50
kohms.

Whad' ya gotta lose? Just 2 resistors!
