|Orpheus사는 SWISS에 위치하고있으며 2001년 창업이래 하이엔드 오디오시장에서 최고의 자리를 군림하고 있는 제조업체입니다.
고급스럽고 윤기있는 소리의 대명사 Orpheus를 저희가 국내공급유통계약을 체결했으며
새로운 라인인 Absolute라인과 플레그쉽라인인 Heritage라인제품들을 하나씩 국내에 소개해드릴 예정입니다.
제가 지금까지 들어봤던 하이엔드오디오 기기중 가장 제취향에 맞고 꿈의 기기였던 Orpheus제품들을 직접 유통한다는것에 가슴이 설레이는중입니다.

전면창의 디스플레이부(이전 4인치에서 7인치)가 커졌으며 앰프의 핵심모듈과 설계가 완전히 바뀐
2018년도 신형 파워Heritage 앰프입니다.
앰프의 첫느낌은 Orpheus 특유의 아름답고 고급스런 음색을 가지면서도 스피커를 휘어잡는 막강한 구동력을 겸비한 하이엔드 파워앰프란 개인적인 견해입니다..
Heritage Power Amplifier
The Heritage power amplifier is the latest high-end amplifier from Orpheus. Its internal topology is based on a complete dual mono architecture. The amplifier has several operating modes: stereo, mono and bi-amp. The rated output power is of 2 x 250W in stereo and bi-amp mode. In mono mode the output power is of 1 x 1000W (on 8 Ohms). Using two separated power supplies and amplifier boards in stereo and bi-amp mode, makes the two channels of the amplifier totally independent to minimize channel-to-channel crosstalk. In mono mode all the cards are interconnected together in order to deliver the maximum power to the load. The different modes of the amplifier and its high power allows it to be used with a wide range of speakers.
The power amplifier uses a class AB output stage based on four hand matched pairs of mosfet power transistors per amplifier board. Mosfet transistors advantages are numerous compared to usual bipolar transistors. Lower ‘ON’ resistance and the way that the power is identically distributed between the transistors makes them more efficient to transmit more power to the load rather than dissipating it as useless heat. Mosfet technology also has higher switching speed resulting in a faster, sharper and more accurate response compared to bipolar systems. The output stage is biased with a precise voltage to set the operating point of the power transistors to get extremely low THD and exceptional audio performances (THD of 0.01% for 200W on a 8Ω load in stereo and bi-amp mode). Thermal compensation of the output stage has been also developed in order to avoid overheating the transistors when they are strongly solicited. Several internal protections are constantly monitoring the instantaneous power consumption, power supplies voltages and currents and heat sink temperatures of the amplifier.
The two low-noise power transformers are able to provide a total amount of power of 2000VA to the amplifier when used in mono mode. The total capacitance of the power supplies in mono mode is more than 180mF. The oversized power supplies guarantees the unit to provide large peak currents and stable voltages even when delivering high output power. Heat sinks have been cleverly integrated into the chassis to optimize heat dissipation assuring perfect operating conditions. Its outstanding specifications, imposing size and weight (50kg) is followed by refined and stylish curves that makes this anodized aluminium piece of art remarkably stand
