In my less than optimal, low ceiling, 12X17 media room, the Bottlehead 6DN7 S.E.X. amp with Pi 2 Towers is satisfying this old rocker to no end. Hands down. Simple as that. Of course, the Paramount 300B with the same speakers puts me in the front row!Put that Foreplay III together, it has plenty (10dB) of gain.
