What do you mean waste of time. You talk like making tube gear is a waste of time. Engineering is not only about solid state side of thing. Engineering is engineering. A good engineer will make a Tube, solid state gear in Audio side of things. Yes, even speakers. Or just maybe, even cars & airplanes. Doesn't matter. Most fall short so choose to go one route because they can't hang with both side of things and it's 100% understandable. It's cutting someone short of their engineering when you limit. I thought Rob made the CD player BluMK2? Who knows what he will make for Chord in future. Whatever he makes, with his musical input and engineering, I think it will be good! And I hope Chord and Rob engineer future headphones, speakers, and even 250WPC class A amplifiers. It sure will be nice to see a Chord's version of KEF LS50Wirless with Rob's own DAC, AMP, and own engineered Speakers All-in-one put out on the market. I do think it will be alot of work though. Maybe too much.
