I have a non Bottlehead system. This is at the office. A refurbished KLH model eight that is on all day with FM. Complemented by a Garrard 301 (I LOVE these tables!) with a viscous damped tonearm and a Denon DL-102 (Work in progress). Phono preamp is the very rare KLH Model eight preamplifier. I don't have high expectations of this preamp since it is a passive unit, that is, it seems to be a passive RIAA network without any gain before. But then again Henry Kloss wouldn't have released a matching pre for the Model Eight that didn't sound good. Time will tell. Sorry for the crappy cell phone pics.
