所有MEDEA都能升级MEDEA+ ！！！
MEDEA+此次为全新设计，理应取个全新的名字以示区别，但是Dianel weiss是一位非常有
责任心的老先生。他在设计MEDEA+时就下决心一定要能使最早的MEDEA用户都能升级，所以
我们能为所有MEDEA用户提供更换全新电路板升级至MEDEA+的服务。（寄回瑞士）
MEDEA+ 此次为惊人的全新设计，是28万美金定制DA/AD WEISS MAYA的精华浓缩，使用了参
考级的32/192芯片，并配上了8片纯甲分立放大模块，音质提升之大，可谓惊人天人！

具体参数如下：Discrete OP1-BP – a truly transparent, discrete operational amplifier module.
A NEW I/V CONVERSION AND OUTPUT STAGE FOR WEISS FLAGSHIP MEDEA+ DIGITAL TO ANALOGUE CONVERTER
Superb noise performance:
  • 1nV/√Hz voltage noise density (1kHz)
  • 30nVpp voltage noise (0.1-10Hz)
  • 0.7pA/√Hz current noise density (1kHz)
  • 80pApp current noise (0.1-10Hz)
  • no common-mode current noise from bias cancellation
Outstanding distortion specifications:
  • THD+N -152dB (+20dBu, 1kHz, 22kHz BW, 600Ω)
  • THD+N -148dB (+20dBu, 10kHz, 80kHz BW, 600Ω)
  • distortion spectrum consists almost entirely of 2nd and 3rd harmonic
  • no significant crossover distortion, even with 200Ω load
  • no significant common mode distortion, even with very high source impedances
Impressive AC performance:
  • 50V/µs slew rte, highly symmetrical
  • 95MHz gain bandwidth product
  • 700kHz power bandwidth (20Vpp into 600Ω)
  • 300kHz power bandwidth (20Vpp into 200Ω)
Superior DC precision:
  • offset 10µV
  • input bias current +-60nA
  • input offset current +-10nA
Excellent load driving capability:
  • 27Vpp(+21.8dBu) in 200Ω (+-15V supply)
  • 20Vpp(+19.2dBu) in 100Ω (+-15V supply)
  • 10Vpp(+13.2dBu) in 50Ω (+-15V supply)
  • adjustable class A output current, factory trimmed to 30mA
  • very low output impedance
  • extensive short-circuit protection
Salient insensitivity to power supply deficiencies:
  • very high PSRR with little degradtion towards high frequencies
  • individual RC decoupling of amplifier sub-circuits eliminates the interaction of the various amplifier stages and makes the amplifier insensitive to power supply inductance
  • high performance on-board decoupling capacitors, 2.4µF total
  • no need for additional external decoupling capacitors
  • recommended power supply range from +-5V to +-18V
Carefully thermal design:
  • excellent stability of any bias condition
  • full thermal isolation of the sensitive input stage from the power output stage
  • fast settling of bias conditions after start up
Dimensions:
  • 42 x 28 x 17mm (1.65 x 1.1 x 0.67 inches)
  • API2520 standard pinout
