Unsatisfied with Esoteric K-01: Alternatives?

@Guidocorona: One reason I've waited 6 months is because I've been diligent about burning in and trying the different filters and combinations on the K-01. While there is a marked difference between them, I still haven't found one that can match the Reimyo for warmth, richness, and musicality. It may be because the Reimyo did 8x oversampling while the K-01 is capped at 4x, and it does seem generally true that oversampling adds a sense of richness to the music. I think I found the FIR filter slightly richer, tonally, than the SDLY, but the SDLY was more natural sounding.

@Others: Thanks for the suggestions. I'll look into them.

@Azjake: The Accuphase gear does look very interesting, but super-expensive as well, especially for the two-box combo. I'll make it a priority to try it out, though.

@Guidocorona: I do have the K-01 in balanced mode. I'm not a fan of the DSD filter on CDs, though it does seem to sound different than the DSD filter on SACDs. The only thing I dislike about its performance on SACDs is a dry, recessed midrange that over-emphasizes the treble and bass. I'm a mids freak so this is a major con for me. Luckily, my SACD collection is small compared to my CD/FLAC collection. As for the Esoteric clock, I did audition and honestly couldn't tell any difference at all. I can't imagine why a clock would be at all useful for a single-box player. As for cabling, I use Virtual Dynamics, which are copper cables with a house sound that's very rich and full, so the lack of warmth/richness I'm hearing in the K-01 certainly isn't a cabling problem. I don't have any conditioning, but have my system running directly to two dedicated lines. I usually listen late at night so I've never thought power conditioning would help much on my system.

@Dob: For Vibration control I have a Monaco Modular Rack. Getting a wood-based stand might help, but I can't imagine it helping to the degree I'm talking about. As for a server, I had a custom PC built to the specifications that Goodwin's audio recommended (basically the PC is isolated and dead-quiet, built specifically as use as a server, accessing my music from an off-network Synology NAS).

@Autosports:

If you are talking musical versus analytical, both two players are among the most full bodied, warm, musical machines out there. There is something very wrong going on if that is not coming through.

I think the only thing that's "wrong" is that it isn't as full bodied, warm, and musical compared to my old Reimyo. I haven't changed any of my equipment since I went from the Reimyo to the K-01, so it would be awfully strange if my other equipment was the problem as opposed to the K-01.

@Guidocorona: Yes, I'm thinking the K-01 simply isn't my cup of tea. I still very much believe it's a reference level player, but at this level it really is about individual preference. There are numerous things the K-01 does better than my old Reimyo, including treble/bass extension, dynamic impact, and macro-detail, but I still feel something is missing when I listen to, eg, female vocalists that were so magical on my Reimyo and now sound rather lifeless and dry on the K-01. On the other hand, the K-01 is more exciting than the Reimyo on large-scale, dynamic music, but I tend to listen to smaller-scale stuff more often.

@Edorr: I do have my eye on MSB's products, but they are also very expensive and I dislike two-box options. Still, they're something I'm considering.

Thanks for the excellent info, Elberoth. At this point I'm definitely leaning towards Accuphase, though the 901 combo is a bit more expensive than what I was looking for. The 801 may hit the sweet spot with regards to price and the sound I'm looking for.
