Room-filling, beautiful sound. I'm amazed that as the volume goes up, the sound doesn't distort. Probably the nature of it's approximately 25-35 wpc. Instead of just getting louder, the headroom expands and fills. "Budget"? Yeah, in 1974; but the quality of this silverface is on par with Marantzes, and is subjectively superior to modern gear I heard before going this route. Great phono stage. Two tapes. I use "AUX" to run my laptop. Spotify sounds pumped on this baby beast, too. Easy to service.
