@audio-satisficer I agree with the above comment about not building warmth into your system via the DAC. I am also wondering if there is a contradiction in wanting warmth but preferring a clean sound. I take your use of clean to mean detailed. This makes me think there is a contradiction here. Nonetheless, I prefer detail from my DAC. But I also like the tube sound and soundstage, depth and imaging one can get from tubes. So my recommendation, is to go with a good R2R ladder DAC. That is where the detail will come from. I have a Denafrips Terminator Plus and I love it. But there are a range of Denafrips DACs in different pieces. All have been well reviewed. Pick the one that is in the top end of your DAC budget. If you don't see a used one, then go to Vinshine Audio and order one. Alvin Chee the owner is a pleasure to do business with. All those DACs are R2R by the way. As for the warmth you can either look at a tube preamp, tube integrated and or tube power amp. You apparently didn't like the Freya+. You might have better luck with the new Doge 8 preamp or a Backert preamp. I think PrimaLuna makes a preamp too. There is also a tube stage in PS Audio's BHK Preamps and amps. Rogue Audio makes a fine tube preamp. There are many others. But bottom line is look for detail in your DAC and complement it with warmth in the preamplifier or amplifier.
Different R2R DACs
Several months ago, I bought a used Hono Spring Level 2 DAC to see how R2R would compare against my Mytek Brooklyn DAC+. I like the Brooklyn+ a lot, but, given the other components in my system, I'm thinking about building in a bit more warmth (without losing significant detail). I'm not looking for sweetness or holography. Unfortunately, I was thoroughly unimpressed by the way the Holo Spring Level 2 smeared the music. I returned it within two weeks. Perhaps the unit I bought was defective (though I bought it from a highly reputable seller of used equipment), but it started me wondering how much of the hype surrounding the newer generation of R2R DACs was just that, hype. However, I keep seeing so many glowing reviews of reasonably priced R2R DACS from Denafrips, Aqua, Lampizator and others. So I'm wondering whether I should give them another try. Unfortunately, where I live the only real (suboptimal) option is to audition by purchasing one DAC at a time. Before I start down that road again, I thought I would ask the collective brain of Audiogon about how much of a difference I might expect, as against the Holo Spring level 2, from a new Denafrips Pontus II or used Terminator II, a used Aqua La Voce or Lampizator, or some other R2R DAC under $5K. I don't require require resolutions greater than 24/192 (beyond which I discern no difference). I do like the option of MQA decoding, but it's not a deal breaker.
The rest of my system (source components aside), at present, include a Parasound JC2 BP preamp, a pair of VTV Purifi mono amps, and Harbeth C7ES-3 speakers.
