L’ampli avait été évoqué dans le fil du SR1A mais n’avait pas son propre sujet.
J’ai l’impression qu’il est dorénavant disponible donc je lui ouvre celui ci.

Qui semble pour le moins enthousiaste:
Overall
I would say this amplifier is an exemplification of contrasts. It delivers slam, impact and punch, while simultaneously being deft, delicate and nuanced. It plays deep, with weight and gravitas, providing a very solid musical foundation … without sacrificing speed or dexterity. It luxuriates in its mid-range delivery, yet somehow manages to maintain balance with both upper and lower registers. It can kick like the proverbial mule, with impressive dynamics - even with conventional headphones, yet does not exaggerate or gloss-over the subtlest, gentlest, tiniest reverberations in vocals or strings. It renders music as a cohesive whole, allowing you to delve into, and focus on, the details of any aspect of it - yet without exaggerating the prominence of any individual element.
A noter également des tests intéressant avec de nombreux autres casques (utopia, Stelia, abyss, hedd, Susvara et bien d’autres).
