Grazie per il feedback lizard.
Leggendo in giro ho visto che fra le sue qualità c'è la capacità di ricreare il soundstage in modo davvero efficace. Inoltre sembrerebbe che sia abbastanza difficile da pilotare.
"Before we move on to talk about the sound of the K500 and the K501, let’s talk about amplifier requirements of these two headphones. They are one of the hardest headphone to drive, next to the likes of the K340. Why? I have no idea, but the K501 are harder to drive than the K701 (75 ohms), as well as the HD650 and the HD800, and the K500 are not so far behind it in terms of amplifier requirements. Both the K500 and the K501 may be rated at 120 Ohms, but they are far more difficult to drive, than headphones with higher impedance ratings such as the HD650 (300 Ohms) and the HD800 (300 Ohms). Not only do they require a high amount of gain (roughly 25% more on the volume knob than the Sennheisers or the Hifiman HE5 Orthodynamic), but the K501 also requires quite a high amount of current. So far, the only other headphone that’s harder to drive than the K500/K501 are the K340, possibly the K1000, and some vintage orthodynamics. Some amplifiers may have enough voltage gain, and so you can get a good amount of loudness from these headphones, but that doesn’t mean that the amplifier can supply enough current for these cans."
