Hmmm so I didn’t get too much time with it, but so far I would say the sonnet is a bit more neutral leaning than the spring, it’s a bit more forward with its detail, the holo has better timbre but the sonnet might actually be quicker, the holo is a bit smoother and more forgiving, honestly both are on a similar tier with just a different sound, personally my preference for something a bit smoother and warmer thicker sounding is with the holo but if you are looking for something more neutral and capable but also not harsh for fatiguing the sonnet is great. Regarding soundstage and imaging I thought the holo was more spacious sounding, but the sonnet might have a bit better imaging. The holo might have a bit more impact here as well
Nice, the hugo 2 is a surprisingly solid dac for being a portable ish lol, honestly I might rank it higher than the adi 2 tbh, it’s more resolving, faster, better spatial recreation and separation, with a bit better dynamics and punch imo
Yes, I do think you can get more out of the kte or sonnet imo. In terms of signature the sonnet is going to be closer to the hugo 2 as both are going for more neutral and resolution forward, but the sonnet is going to be making the larger jump technicality wise and is also going to be a bit more natural. The kte would add a more touch of organicness to the sound and smoothness, while maintaining it’s resolution, and give a bit more holographic sound imo. It’s really hard to put into words what the differences would be, mainly because you are absolutely working in the realm of intangibles, but I can tell you that it’s absolutely a worthwhile step up to get the most out of your system
Going off @Veritas here, my main living room setup might look very off balance at first, the electronics are much much higher tier than the speakers themselves, the speakers aren’t on the same level as my electronics are, but that’s ok actually. From my experience once I found a speaker I really liked, any upgrades in electronics have gave great benefits to the speakers, even where I can justify spending on electronics that cost like 5-6x what the speakers do, and still fully appreciate the returns. IMO if you really love those cantons, in the future I would suggest you go even higher on your source gear and reap the benefits. Once you get into the higher end speakers, it’s no longer a game of trying to find the most performance for the money, it’s trying to find the best match for your system and your preferences, since for speakers for example sometimes spending more on a perceived “better” speaker doesn’t mean it’s going to be better for you, mostly anything in the high end side of things is going to preform competently, you just want to try and find what you like to listen to the best, even if that means going with a cheaper speaker that you really like and going nuts on electronics for it (but again this can depend on the situation and setup at hand), as that can keep the sound you are happy with but elevate it further
