Hello fellow headfiers! The following info has just been posted at Creekaudio's website: Quote: CREEK AUDIO ANNOUNCES NEW PRODUCT RELEASESÊ OBH21/OBH21SE HEADPHONE AMPLIFIER The OBH21 is a miniature audio amplifier specifically designed to drive two pairs of low to medium impedance headphones from a line level source. The OBH21SE is a high-end version using more expensive components and power supply. DonÕt be fooled by the size - Creek has left nothing to chance when it comes to performance The OBH21 and OBH21SE are compatible with any source at line level. For example, an average output level CD player can be connected directly to the input of the OBH21/21SE, just as it could be used in conjunction with a stand-alone pre-amplifier or integrated amplifier which doesnÕt have a headphone output. The OBH21 is not designed to be connected to the high-level speaker output of an integrated or power amplifier. Output level is controlled by the high quality volume control on the front panel. The OBH21 and OBH21SE are the first of the new style OBH products to be released. With slightly longer casing, these models feature a stylish aluminium front panel in a silver finish. http://www.creekaudio.co.uk/news/index.asp The following questions remain unanswered, though I've just e-mailed Creek with an inquiry. (I'll post any new data as soon as arrives in my mailbox): 1. What are all the basic differences between the OBH-11 SE and the OBH-21 SE? 2. Does the OBH-21 SE contain better capacitors than its predecessor the OBH-11 SE? 3. Does the OBH-21 standard (non SE) edition of this amp contain only one headphone jack like the standard OBH-11? (see 'EDIT' comments below). 4. Will the OBH-11 SE be discontinued in favor of the OBH-21 SE? If anyone has auditioned any of those new devices, a review would be greatly appreciated! Cheers, Alex Altorfer Edit: Well, by reading the text quoted above more carefully I realized one can infer that the standard version OBH-21 also drives two pairs of headphones. Sorry about that. My guess is that the OBH-21 and the OBH-21 SE look absolutely identical externally speaking. Perhaps the standard edition OBH-21 is powered by a walwart power supply, though I'm not yet sure about this.
