Lenny Florentine sits down with Rich Pinto from Treehaus Audio to talk about the rare intersection of industrial design, old school tube knowledge, and modern execution. Rich shares how his background building Heathkit projects and designing cars at General Motors shaped Treehaus, then walks through his obsession with making gear that looks like it belongs in the living room and sounds even better than it looks. This episode gets into the why behind the wood, the open baffle approach, and the design choices that make Treehaus instantly recognizable. They dive into Treehaus tube electronics built in Connecticut, including multiple 300B amplifier variants, a transformer coupled approach that avoids capacitors in the signal path, and a phono stage built around an LCR style correction scheme. Rich breaks down why low wattage can go further than people think, how tube clipping behaves differently, and why he chases realism over accuracy. Plus, there is a detailed look at Treehaus speakers with live edge baffles and field coil drivers rebuilt from vintage telephone designs, and why that mix delivers speed, nuance, and dynamics even at lower volume levels.
