Since I just received the K&K and am still tweeking the denon 103r I am only saying with limited time, that the K&K sounds sweeter, projects the music forward a bit in between the speakers, but also has excellent soundstage I am hearing things well beyond the back wall, it is more inviting so- it makes me want to stay longer and continue listening, it also sounds a bit softer in treble range in a way but yet still reveals details in the treble range, though I could also have said that it some how chops off at the extremes(high) but not sure if that's what it is doing- I mean it's pleasant but it makes me yearn a bit for that shimmering sound but maybe that's just an emotional thing and a hint wanting more or spoiledness from my end.
Oh and at the other end the bass is absolutely beautiful, it is full sounding and keys are distinguishable and no cut off of low frequencies as far as I can see for now.
In the end I have to say that it works for me with the denon 103r and of course everything downstream which is to me lucky that I happen to have the right things in the right places.
I will be picking up other cartridges and tonearms as finances allow, then I will know if the K&K is the top dog in this wide price range of under $2500.
I really should mention too that I haven't even begun to compare the speaker wires(have 4 to choose from) and interconnects(don't have much choice now) just yet.
