The only point without a real argument against it was Takato's observation that many R10s are now rotting away and might not be the best choice right now. However, everyone has his or her own tastes in audio and the K1000, Abyss, etc. all have their fans. They're all considered top-tier headphones in the community as a whole. There's no reason to simply reject a certain headphone from the TOTL category because it doesn't fit your sonic preferences.
