Esoteric K-03 or K-01

After many reads and auditions I am ready to pull a trigger on esoterik K-03 player. I also have the opportunity to get a new K-01 for a great price, but without being able to audition it and still a few $$$ more, so it is dificault to commit to.

Those who had a chance to hear/have both players, how much K-01 is better than k-03?

May be for my system K-03 will do fine and K-01 is overkill?

I intend to run Esoteric player direct to amplifier, how much K-01 may sound better direct to amplifier in compare with K-03?

My speakers are Marten Django XL that driven by ML # 532H.
Thank you.
