I wonder if this active circuit is something that can be implemented in tube amps.
Normal Jot is rated to 7.5 watts/16 Ohms. IF it COULD deliver power into 8 Ohms, it would have similar output rating as something like a 300B SET amp, which are typically 8-10 watts/8 Ohms.
Being curious, I hooked up SR1a to my Elekit TU-8600R 300B SET speaker amp even though I know Raal recommends at least 100 watts. The amp immediately started to clip even at pretty low volume levels, at levels you would use if someone was sleeping in the room right next to you.
However, when I changed the interface box to the amp’s higher impedance speaker tap, the allowable volume level increased significantly. Playing mostly vocal music like Leonard Cohen “You Want It Darker,” I was able to achieve volume levels I would use if somebody was sleeping, say 5 feet away. Still way, way below normal listening levels but just enough to begin to hear that 300B texture and richness. And as 300B afacionados know, it was MAGIC.
Perhaps companies like Woo, Eddie Current would be willing to at least contemplate about such an amp as Raal sells more ribbon headphones in the future and demand goes up. I can hope…
