Hmmm, so what else can I add? M0N pretty much nailed the description in his mysphere article, and I couldn’t agree more.
For reference, the mysphere was mostly used and I replaced the stock psvane 300b with WE 300b (haven’t tried the stock yet), kept the stock Electro-Harmonix 6bm8/ecl82 for now.
Gotta say, that burn-in took a looong time so I just left it on for the most part as suggested. That being said, I was able to get a good 3 to 4 sessions in for some initial impressions…
In a word, well two, I find the ha300 to be “unassumingly great” (good article title? lol). Because of its modest approach, it’s not an amp that will particularly impress though that’s not always a bad thing. It does everything well that you don’t really feel like you’re missing anything, it’s solid all-around with great tonality and control.
What I really like about the amp is how well it balances things. It’s not overly dry or overly wet, overly energetic or overly relaxed, just straight down the middle. And while that sounds kind of boring in words, it’s not really in practice/listening… at least not to me lol. It’s kind of like getting a B+ in every single subject, not overly impressive on paper but in reality still really good.
As per how it is with the mysphere (since that’s what I mostly got it for), there’s really nice synergy. It didn’t upset any of the balance and overall just elevates it really well. The midrange though, in combination with the WE 300b and the gingko isolation products in tandem, is fantastic! Very dynamic, weighty, engaging, agile, clear, and silky/velvety. The pairing with the Satie DAC is also great, it adds nice energy and maximizes resolution while keeping the balance.
Compared to the Allnic, it’s such a different experience entirely. But, in general, I find the Allnic to do its best to not get in the way of the chain and just present whatever is plugged into it with as little emphasis/exaggeration as possible. With the modwright it’s very obvious you’re listening to it, if that makes sense. The 300b certainly has a certain and particular “sound” to it. It took me a very good while to “accept” this kind of sound but once I accommodated to it I really enjoy it. I do think I still technically prefer the Allnic but so far I enjoy listening to music more on the modwright, it’s also more forgiving. Only time will tell, but this might be the case where what I know I like is not actually what I prefer to listen to most of the time. Idk, still learning about it lol (and it’s still early).
In summary, the Allnic has no tricks up its sleeve, the modwright also doesn’t but it teases you a bit and pulls you into its pace. In any case, I like both! Would love to see how it does as an integrated but probably won’t happen
