I saw that comparison. I actually find the Bartok a bit bright as it is, so more presence or brightness could be too much, but the comments about bigger soundstage and more energetic, fluid, presentation sound very encouraging.
I think digital inputs are a really overlooked part of this comparison. The Mola Mola ethernet input is Roon only, and with the Makua you lose the I2S inputs, but gain an analog volume control instead. In this case, optimized ethernet via Roon and an audiophile switch will be the best input, whereas on the Tambaqui it could be that or I2S.
I still have the Bartok and recently got an Uptone EtherRegen, which is in the early stages of burning in. So far I can say that 90% of the sonic issues I had with the Bartok came from the ethernet input, and much of the rest had to with cables that were too bright (silver) and rack mounting. In any case you use ethernet, you have to get an EtherRegen or similar type switch, and decent ethernet cables.
I envy anybody who has the chance to do an extensive comparison between these two DACs, but if there is one thing I can draw from my experience with the Bartok and digital inputs: Until you have a really high quality and low noise digital input, itâs hard to get a true sense of the character of clean/analytical DACs like this.
Now that I am honing in on the Bartok at its best, I can see that things one might like or dislike about it are more like emotional responses to the character of its presentation. The Bartok has this kind of psychedelic colorfulness, and ability to bring out patterns in motion and rhythm, swooping dynamics, etc. but it is really absent any romance, sentimentality or color that might be pleasing to some listeners. It doesnât have a comforting sense of body, weight, or smoothness, although nothing is lacking in proportion.
I find at this level of resolution, I kind of want some kind of grounding âanalogâ flavor or warmth because it is so revealing. My sense is the Mola Mola DACs are probably somewhat similar, but in a faster and more lively manner. That energized presentation might make up for the lack âanalogâ character.
And for what its worth: The Bartok headphone amp really isnât my favorite so far. Iâm still using an Audeze The King and LTA MZ3. For anybody who is into headphones and looking at DACs in this price range, there are better external HP amps so I would choose by the DAC itself.
