RE: Does it need burn-in?

Here under the link.

My crossover is getting there; I've had a major change yesterday after some more hours intense burn-in (blasting the circuit with much higher signal voltage than what I normally do when listening, amps turned off): midrange detail is coming upfront, treble is now composed and more natural, less piercing - the whole presentation got at the same time more open and less bright; soundstage got finally wider than the speakers and phasey effects in recordings finally can do the "hey I'm here behind your left shoulder" trick that never fails to impress the "bluetooth speaker generation".

I really had two major stages of burn-in that I could hear: I'm wild guessing: at first the electrolytic caps (there aren't so many and they are all the same) then, I suppose, the films caps... meanwhile all the rest (op-amps etc) was gradually settling in.
It's probably still burnin-in since it hasn't been so many hours yet, but yesterday it was FINALLY enjoyable to really just listen music and not just wonder about the sound. A big step has passed.

As a disclaimer regarding the product page: the last review is mine. I wrote it after the first burning stage was complete - after spending a couple days wondering why my 49$ AliExpress crossover sounded better than the 10x more expensive K231, and I was so happy and relieved that I had to write a review THEN. Besides, Mark from Sublime Acoustics had done a great job to deliver the crossover with less waiting time than initially announced and was very professional from the beginning and I wanted to sincerely promote his product. Everything I said there is true - but after some more days I still found that many recordings were still overly bright and the whole presentation lacked liquidity and "relaxness", hence my post here; I'm happy to say the sound keeps changing in the right direction and I don't have to regret having written a very good review.
