Raal HSA-1b - Headphone/Speaker
Publié : lun. janv. 25, 2021 11:11 pm
Bonjour,
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.
Load Impedance:0.3 Ohm – infinity
Output Power (one chanel driven):10W /8Ω, 20W/4Ω, 40W/2Ω, 55W/1Ω @ 1khz/sine
Ribbon & Headphones Drive: RAAL-requisite SR-1a, Dynamic & Planar Magnetic
Speaker Drive: 8Ω, 4Ω, & 2Ω Loads
Freq. Response:100mv/ in/sin. 15hz – 500kHz
Power Bandwidth:100kHz (-3db) at 1khz
Distortion:< 0,5% at 1khz
Signal to Noise Ratio:Better than 90dB
Input Impedance:40 kOhm
Sensitivity:0,5V /40kOhm
Input:IN1- 2 RCA, IN2 – 2 XLR
Max Power Consumption:150W , without signal 25W
Dimensions:H 90, W 218, D 320mm (3.54 x 8.58 x 12.60 inches)
Weight:5,3kg (11.68 pounds)
Et je commence par une première review :

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).
