So I’ve seen this on a few sites like upscaleaudio and crutchfield that the Mark Levinson No. 5302 has been marked down from $11,000 to $6,600. Seems like a great deal to me. But also makes me curious. Why would they mark it down so much?

It’s really not so simple. The specs show:
Measuring at 20kHz, harmonics are ultrasonic and inaudible.
If you were to say the amplifier measures less than 0.04% THD at 1kHz into an 8 ohm load, most would think it’s excellent and inaudible.
PPM isn’t applicable for audio because there are no parts to count.
