@melm Hi yes I agree -- there are always trade-offs. I think the modular nature of some DACs is a very attractive feature, but no it’s not a universally appealing solution. Companies like Bricasti and Ayre have shown over the years their commitment to original owners via upgrades, and I appreciate that. One of my early digital purchases was a Naim UnitiQute, not long before the Naim Atom came out. The Atom was a major advance (I "had" to have it), but it was an expensive (to me) proposition to get the Atom, having just purchased the Qute -- whose value of course tanked when the Atom came out. In retrospect, I wish I had chosen a modular product. Or at least a dealer with a good trade-in policy. That experience colored how I feel about boxes, particularly digital boxes, that are not truly upgradeable. So that was my introduction to hifi, and it’s stayed with me.
I did choose the most expensive Holo to highlight the idea, but I think it holds at other price points as well. Take the Musetec at $3100 (the factory price keeps going up), add a decent streamer like the Lumin at $2000+, and you’re not far off the Bricasti M3 + network card at $6500, and you’re above the Sonnet Morpheus/Hermes at $4500 or whatever. I won’t get into the substance of how they sound different, just pointing out that from a price perspective, there is quite a bit of overlap between excellent Chinese DACs and excellent N.A./Euro DACs.
@reven6e makes great points on the Weiss. I haven’t heard the older Weiss DAC, but that’s consistent with what others have told me. I found the current Weiss "musical" (i.e. a pleasure -- when listening, I wanted to keep listening) but yes it’s a cool, analytical kind of pleasure (imagine the pleasure of understanding a cool new scientific experiment, vs. the pleasure of losing yourself in a movie), so system-matching becomes extra important.
