Thanks for all the detail on the various options available with the K-01. I talked to dealer in Canada who is extremely experienced with Esoteric gear including the P-01/D-01, VU models of both, P-03/D-03 and as of late the P-02/D-02 and K-01/K-03. The dealer mentioned that the upgrade path is not finalized yet for K-01 to the X model and that the initial upgrade will be limited with a full upgrade from K-01 to X with all diffs accommodated might be in the $10K range.
Matt: Best of luck in your Burmester hunt/acquisition; let us know how it turns out. Send me an in-mail/PM to let me know what you are looking for on the K-01 as I may take this path though the P-02 and D-02 are still haunting me :-)
