With modern amplifiers expected to cater for so many new source devices, the Phono capability, once very common, is one of those built-in features that has disappeared in recent times. The engineering team at Creek Audio has always loved the benefits of vinyl records and continues to work on technical and sonic improvements to its range of Phono amp options, be it the stand-alone OBH or Wyndsor or plug-in Sequel types. Tasked with designing a replacement for the long running OBH-15, the team came up with some valuable improvements and additional features; surprisingly they made them all fit into the original OBH-sized casework.

The OBH-15 mk2 has a completely new circuit design, with a discrete transistor MC and integrated circuit MM stage. Unlike its predecessor, the new amp has multiple gain settings and matching capabilities for capacitance and resistance. The signal required by most modern amplifiers is described as being 'LINE' level which is, in technical terms, between 200 and 500 milli-Volts sensitivity with a flat frequency response. Unless your amplifier has a specific 'Phono' or Disc input, the level will be too low to play vinyl and the frequency response will be wrong.
 
The OBH-15 mk2 is small device designed to boost the signal and introduce an R.I.A.A. frequency response characteristic to provide the most accurate reproduction of the recording. The OBH-15 mk2 is small and very stylish. Designed to complement the Creek full sized range, it has an impressive solid aluminium front panel with either a silver or black finish. Its extruded black aluminum case is fitted with turned aluminium disc feet and sound absorbing Bumpons.
 
Technical Specifications:
  • THD+ noise at 2Vrms output: MM (40dB gain) @ 1kHz = 0.002% / MM (40dB gain) @ 10kHz = 0.003% / MM (50dB gain) @ 1kHz = 0.007% / MM (50dB gain) @ 10kHz = 0.007% / MC (60dB gain) @ 1kHz = 0.005% / MC (60dB gain) @ 10kHz = 0.005% / MC (70dB gain) @ 1kHz = 0.011% / MC (70dB gain) @ 10kHz = 0.012%
  • Channel Separation: MM (all gains) 1kHz = >70dB / MC (all gains) 1kHz = >70dB
  • Frequency Response: 0.5Hz - 100kHz (+/-0.5dB)
  • SNR: MM (40/50dB gain) = 76/66dB / MC (60/70dB gain) = 77/70dB
  • Overload Margin: MM (all gains) 21.7dB@50Hz - 21.7dB@1kHz - 21.7dB@20kHz / MC (all gains) 20.7dB@50Hz - 20.7dB@1kHz - 20.7dB@20kHz
  • Output level: 6.1V rms Maximum
  • Output Impedance: 100 Ohms
  • Gain: MM = 40dB/50dB / MC = 60dB/70dB/80dB
  • Matching: MM = 100pF or 200pF plus 47k Ohms / MC = 100pF or 1100pF plus 100 Ohms or 510 Ohms
