I have Foreplay, Foreplay 3, Paramours, and the Original Sex kit modified with new iron. I find myself alone at work and just cranked it up. I'm hooked to a Dell laptop with Clementine a Fiio E-17 Dac and Insignia Speakers.
Sometimes I think the Sex amp is the most rich, detailed, with deepest soundstage and best separation of all the kits I've ever heard. In fact I think that more than just sometimes.
Major mod to the Amp is the addition of Auricaps and a DACT
I've had it for years and it may be the best sounding stereo I have. I need to take this thing back home maybe and bring something else to the office. I have the Sexy Speaker Kit with baffle correction as well just not here at work right now.
