Title: A lot of fun
Author: Jochen Donner
Translated from the original German article
All these ingredients resulted in a high performance acoustical power plant nearly free from distortion. Due to this optimised design, the efficiency of the driver technology has considerably improved. The consequence: The T 90 develops, probably because of this, an audible more precise reproduction, sounds considerably louder, plays with ease and therefore clearly better.
It always sounds most melodiously. [...] The Tesla sound appears vivid and lively, but never twisted – a fun headphone.
Its bass boost gives orchestra timpanis a richness which makes them sound more precise and compact. The overall acoustic sound has more weight and volume. Furthermore, the rapidly oscillating diaphragm creates a clear perceptible bass scaling. Musicians are standing on a stage, which is rather small; but instruments and voices are separated and can clearly be localised. Those who like listening to rock music will benefit from this (...). Those who enjoy classical music will be glad about the precise, almost overabundance reproduced by the Berlin Philharmonic orchestra (...)."
Now I can say with a clear conscience that the T 90 especially loves voices: be it the richness of two octaves to the f3 from Roberta Peters (...), be it Petterson Hood‘s (...) intimate, melancholic murmur, be it the highly dynamic in “blue notes” (...) – finest outline and vibrant power of the Tesla headphone transmit each nuance and create a lively directness, searching its match.
