The Trinity brass is incredible. My favourite for almost (except for classical and very instrumental kind of music like Folk and Songwriter) every genre recently!! With the right tips (i use the spiral dots) it has the most engaging and yet balanced tuning i've heard to date. I've demoed the Flamenco for enough time and if the Trinity wouldn't have appeared the Flamenco would be mine. But for me the Flamenco doesn't have this extremely sweet tuned treble (in direct comparison) and this perfect bass/sub bass amount (DD). For me the Trinity brass sounds a bit more balanced. I wouldn't call the Trinity an upgrade though. I don't like this word at all. At the end of the day it's all a matter of taste imo.
... but what i don't get is, that your wishlist includes the Trinity instead of the Flamenco
just mentioning.
However... i wouldn't put one above the other. They are both great and will find their way to adequate owners
Even if i would own the awsome Flamenco i'd consider the Trinity as well
.... but not as already said as an upgrade. The Flamenco would be (next to the Phantoms) my weapon of choice for classical, songwriter and other non-electronic music as they sound for me one step more transparent. The Legend X and the Trinity brass are my faves when it comes to bass heavy Rock, Alternative, Electronic and so on.
If both... the Trinity and the Flamenco would be human i'd say the Trinity is the 28 years old good looking manager with great sense for a good outfit and elegance but he's not really settled down yet because of all the great things to come
The Flamenco for me would be the 46 years old great looking gentleman with 2 lovely daughters and a beautiful wife. His life slowed down a bit. He is a bit wiser and calmer as he knows everything will be good
So i wouldn't call one of these persons better than the other one.
