I'm not saying anything new here. It is just common knowledge.
Whilst I agree with most of your thoughts and I too believe the Elear can potentially be categorized as mid-fi (especially if we're talking about Tyll's wall of fame, for example), one thing I find a little jarring is that the Elear may be a better match for the WA8 than the Utopia based off of the fact that the latter requires "TOTL amp/DAC" to sound its best.
Sure, the WA8 is closer to the price tag of the Elear than it is to Utopia's and my experience with really expensive gear is quite narrow (I own a WA7 for example) but I find it hard to believe that a 2 thousand dollar amp (possibly paired with an external DAC) crafted by arguably the most respected valve device manufacturer in the US cannot adequately drive the Utopia. I refuse to believe you need to spend 16 grand on their WA234 Monoblocks, which after all is their TOTL product, to get the Utopia to sound as it should. Of course, the better the chain, the better the headphones will sound, any properly built headphones nowadays will scale fairly well in my opinion but is that last 1 or 2 or however much % really worth paying 3 times the price of the WA8 to get the WA5 (which isn't even their TOTL) instead? Maybe, but I personally didn't take
@Currawong 's claims that far.
