I cannot describe my Koala as irritating at all. It is quite musical. Maybe my hearing doesn't pick up on those frquencies like some. I've had a few audiophile friends listen to my system and we compared the Koala with a Shanling, Rega Apollo, Arcam CD92 (with the Arcam DCS Ring Dac) and we all prefered the Koala. It was only when I compared the Koala with an Audio Research CD3 MKII, Lector CDT.7 and BAT VKD5 that I noticed how the soundstage depth, width and detail retrieval can become sweeter and more well defined (BAT,AR CD 3 and Lector were all varying degrees more musical and natural). But without those $5K and up players to compare to, I still prefer the Koala.
I have also rolled some Sovtek 6922's in place of the EH6922's and prefer them. I will try some NOS Amperex or Siemens-Halske 6922's to see what improvements they may add.
