Professionally Upgraded Creek OBH-11 SE Headphone AmpStaccato Class A Discrete Op Amps + Rubicon and WIMA Caps The Creek OBH-11 SE is well known as being an exceptional value in modest sized headphone amplifiers. When the included wall wart SMPS is upgraded with a linear power supply many consider it to be quite a performer. Weve taken this OBH-11 SE to a whole other level of performance: with the upgraded op amps and capacitors shes a real giant killer :^P Check out the internal photos: we squeezed some amazing guts into this tiny chassis...the heat sinks from the Staccato class A op amps literally touch the top inside of the chassis extrusion transferring heat to the entire aluminum chassis to keep them running exceptionally cool. Ive got too much gear and need to downsize my collection a bit...my loss is your gain. Guaranteed to be the exact item in photos and to be in 100% operating condition. Product Description: The OBH-11 is a miniature audio amplifier, designed specifically to drive a single pair of low to medium impedance (30 Ohm -300 Ohm) headphones from a line level source. The OBH-11 is compatible with any source at line level. For example: an average output level CD player can be connected directly to the input of the OBH-11, just as it could also be used in conjunction with a stand-alone pre-amplifier or integrated amplifier which doesnt have a headphone output. Creek has re-engineered the casework of the old OBH 11, so the front panel is now much thicker and has rounded corners, new style graphics and the metal logo found on the more expensive Creek products. It is ONLY available in black and is an addition to Creeks range of popular headphone amplifiers. OBH Uni Power Supply OBH-Uni. The OBH-Uni is a 15 Watt high-efficiency multi-region power supply adaptor that replaces the OBH-1 and OBH-2. Creek has designed this to simplify the requirements for OBH products used in all countries. It is supplied with a selection of snap-on power plugs and since it is capable of working from a range of mains voltages from 100V-240V, we are confident it will make life a lot easier for everyone. We have compared the performance with that of the OBH-2 and feel that it is a good replacement. Furthermore, since it no longer works at mains frequencies (50-60Hz) it will not interfere with high gain circuits like the Phono amplifiers and it also does not draw current when connected to the mains but not being used. We are pleased to say that it complies with the new and up-coming regulations that demand power supply adaptors to be high efficiency switching types.
