” As the P49 has a class-G output stage, I monitored its output voltage during one of my listening sessions using the YGA speakers. At my usual listening levels, with Steely Dan’s Gaucho (24/96 ALAC files transcoded from FLAC, MCA B0000868-36/HDtracks) peaking at 90dB (Studio Six iPhone app, Fast, C-weighted reading), the RMS level never exceeded 7V, meaning that only transient waveform peaks were activating the voltage-rail lifters. The P49 behaved like a high-performance 50W/17dBW amp with 6dBW of dynamic headroom.”
