It is primarily a question terrain and space, audible in chamber music but also to the orchestra. Besides, the former seemed to bring out the instruments of a unique place, having said exaggerating. But it is also a matter of precision. What looked like a flash a little fuzzy at the bottom of an instrument of the orchestra takes a precise drawing. Stamps are more individualized. The ear fatigue is increased by the relief, perhaps also because the quality of certain elements of my chain is not sufficient and because my amp Nad is very clear and without excessive sweetness.
It goes without saying that this helmet increases the differences between its outlets, according to their date and their degree of success, but also between the support qualities. I have a lot of tapes recorded by myself, usually marks and quality models. They benefit from the precision of a hand, but take an unpleasant aspect of the other, a little aggressive. If a CD has a scratch or a regular cloc product, the sensation of this parasite becomes invasive. The passage of a recent recording to an older record is felt by a perceived lack of brutal platitude. Yet in comparison to the old helmet, the listening to an old recording, even 30s, is ennobled, finesse and accuracy have improved, but only slightly.
It is likely that with a cheap installation as a mini-chain 4 or 500 euros, the cruelty of this helmet, a consequence of its precision, which highlights the flaws in the make unattractive acquisition. Moreover, rap listeners and more techno find that the bass is insufficient on this helmet, because he is very balanced. Classical music, the traditional EUROPEAN original song, jazz probably, are his domains. I listened to the old rock, it's not unpleasant, but such a headset does not bring really significant advantage. Similarly, if you have a CD player 150 or EUR 200, an amplifier 400, this device will suit you but you probably do not need to go upmarket; the disappointment of a user, purchaser of a better and more expensive Sennheiser, the index is probably the best is the enemy of the good here.
