Rogers High Fidelity KWM-88 “CORONA” | AXPONA 2019

Something new from Rogers High Fidelity — a bit of old-world/new world. On the one hand, you have a completely hand-wired amp with a massive toroidal power supply — the PSU on this guy is 30lbs, all by itself. And on the other hand, there’s an app. And yes, you can change the volume, change the “mode” (ultralinear vs. triode), or monitor the completely automatic tube biasing, all courtesy of that app.


We’ll be looking for this at AXPONA next month. Stay tuned.

MSRP for the KWM-88 Corona: $13,999
