Bartok dCSa nie podejdzie do Empyreanów z banalnych powodów producent podaje że najniższa oporność podpinanych słuchawek to 33 Ohmy a Empyreany na złość zeszły na 31 Ohm. Z doświadczenia wiem że praca na skraju możliwości wzmacniacza to nie najlepszy pomysł i przynajmniej kłopoty z basem.
Zupelnie bym sie tym nie przejmowal, Bartok powinien pociagnac stabilnie sluchawki nawet 8 Omowe. Tak przynajmniej twierdzi dCS:
The Bartok headphone amplifier is heavily optimised for operation into loads of 30 Ohms or greater, but this doesn’t mean that it won’t operate linearly into lower impedances.
"As the amplifier operates in Class A for all practical purposes, the maximum power dissipation in the output stage is when the amplifier is idle. Driving the amplifier diverts this power dissipation away from the output stage and into the load.
"As a result, the amplifier is quite tolerant of lower than rated loads. Into very low impedances (let’s say less than eight Ohms), and at high output levels, there will be an increase in output stage dissipation, distortion will increase a little, and operation may move away from Class A at very high drive – which we define as levels that would not be encountered in any practical situation, i.e. levels that would be hazardous to both ears and headphones!"
