I saw demand for a 100W MOSFET amp, biased as much into Class A as possible, for best sound. I opted against Pure Class A due to inefficiency and room heating heat rejection.  Mono blocks were chosen in keeping with the compact footprint common to the '9' series of products, including the PH 9.0/X/T, Analog Bridge and LS 99 preamp. I felt efficient use of space to be a critical factor in todays world. Chassis and aesthetics are clean and elegant but simple, reducing cost, allowing us to focus on component quality and design for best sonics. Lastly, amber illuminated power VU meters were chosen for a vintage tone aesthetic that I believe embodies the design concept.
