Unsatisfied with Esoteric K-01: Alternatives?

I lived many blissful years with my Reimyo CDP-777, but finally decided it was time to start the transition to PC audio. I opted for the Esoteric K01 in order to have the maximum playback flexibility with CD, SACD, and asynchronous USB DAC. Fast-forward about 6 months and I find myself really missing the warmth, tonal richness, and musicality of the Reimyo when listening to to the rather cold, dry, and neutral K01. It is not a bad player by any means, but I've just come to realize that I'm a musicality guy as opposed to an analytical guy.

Now I'm in a bit of a quandary in regards to how to maintain that flexibility with something more to my taste. Are there any CD/SACD/asynch USB players (or combos) that lean more to the Reimyo's sense of musicality? Harmonix's current line still doesn't do USB input, or decode any thing but PCM up to 44.1. I'm starting to to think my only option is to buy the Harmonix for CD playback and then have a completely separate system for SACD/PC audio playback, but I would love to avoid that if at all possible. Any suggestions are welcome.

Hi George, which filter / upsampling settings on K-01 did you find unsatisfactory? G.

None, I'm just stating the differences I've heard with many Delta Sigma type dacs vs well implemented R2R ladder Multibit type dacs playing Redbook cd's, and this also jells with what the OP is hearing.

I can't see filters, hf or upsampling being able to add jump factor or midrange body to the sound on a Delta Sigma based dac.

George, I'm really sorry to hear that.... Filters on K-01 do a great deal of work. I agree that without filters and with no upsampling, the sound of K-01 is something that only its Moma could love.

Yet, the 5 filter options combined with the upsampling options let the user taylor the behavior of the unit a great deal.... If you enjoy a warm sound, all you need do is select S_dly1.... And then upsample / or not to taste. For me, Nirvana was reach with S_dly2 and 4x upsampling.

Of course, if you are allergic in principle to the very concept of filters and upsampling... That would be a different ball of wax.

You just have to look at many of the very highend dac makers that are going back to implementing R2R Ladder Multibit conversion in their top players. Even though it's far more costly to implement, some even making their own discrete versions of it now.
Because off the shelf ones are becoming hard to get like the PCM1704K, it's still available but so costly for Burr Brown to make, compared to Delta Sigma types, 10 x the price, they will stop making it one day.

Cheers George

2nd what dob says. power cords and vibration control (sistrum!) works wonders.
