Ramon,
speaking exclusively out of my own experience and of my knowledge of myself I’d take the K-07Xs/G-02 path because I’d rather optimise the CDP I have than have a more expensive one that I ‘know’ is not working at its full potential; but that is just me. As I wrote I think that something else than convenience and cost-sensibility is in play here, and if one accepts that the price to pay is not completely performance-related (but when is it in audio world?), well that’s the path I’d take.
I anticipated that I was not after practical suggestions but just opinions; and this is my opinion only; as I’d just follow my instinct I think you should follow yours. I’ll be interested in knowing about your further impressions with either choice.
Best regards
M.
