It's all subjective, and if you have the K2s, maybe just sit pretty or try the SACDs. I prefer the SACD that I have of one to all the other versions of that title that I've heard so far, next for me would be the XRCD minilp copy I have, then the K2, don't have an RVG of that particular title. I'm not as fond of the Hoffmans as others are.
So. . . if you have discretionary income to sample, sample some, but whichever is "better" no one here can tell you. I agree with Robert h. in this regard.
