Metrum Octave versus Eastern Electric DAC

I own an Eastern Electric DAC, the older one with volume control, no mods. Have any of you in the community compared these two units? Would I be better off doing the op amp upgrade, buy the newest EE with upgrades?

I have enjoyed the EE and like it well enough, but I am curious about the Metrum. I would like slightly more warmth, more fullness, a little more meat and bones, without losing any of the detail I now enjoy.
