I've been holding off on more comments on the KWA until I put some more hours on it and had a 36.5 in place to feed it - the amp has about 500 hours on it and a 36.5 is now in place.
I mentioned the strong bass as a first impression in my previous post, driving my Salk HT3's I'm still shocked that this amp can drive them with ease and the bass has become tighter and even deeper with the 36.5. So much so I think Dan should rename the amp 'Thor's Hammer' a much better description of what it delivers than KWA! I clearly have a preference to listen in high bias mode, smoother and more musical in my system than low bias. I also found the amp benefits significantly from a 400-500 hour burn-in - it becomes smoother and more refined with time, patience here is rewarded.
Over the last few years I've found the 'audition by subtraction' approach is the real acid test for me, so this weekend I took the KWA out of my system and replaced it with my MF KW500. The KW500 is a great value and underrated package IMHO and has provided me with a few years of great listening enjoyment. The conclusion was very obvious, I missed the superior detail and musical involvement from the KWA.
I've re-read Srajans review again (it takes a few reads to extract the detail in his reviews) and believe he nails it, the KWA is a magical amp. The only way I can now beat this is with a brace of KWA's to make Thor's Hammers!
