I owned the creek OBH12 SE and thought it was at best OK and I definitely could hear the sonic effect. Most likely due to low quality relays the OBH12 uses. Thanks for the thought though.
i do not see how the creek's relays could affect the sonics, as they're outta the loop after the source has been selected. in fact, the creek will play one source w/o any power hooked up to it at all.
in any ewent, i have found i get the best results by setting my melos pre to a wolume level that has the creek pretty-much max'd out for optimum listening level. in this set-up, it's pretty transparent.
you also may wanna try an audio alchemy dlc. i have one of these powering a korsun integrated for its remote capability, & it seems to be good, but i haven't done any critical listening to judge its ultimate transparency. one of the guys i know on the tuna forum, tho, uses the dlc & he sez it's extremely transparent. based upon my gut feeling of using the creek and the dlc as the *only* preamp between source & amp, i do think it is at least as transparent as the creek. but, it may be its sonic signature, as it is an active digital piece, not passive...
