Power Amplifier - Conrad Johnson SA150

The SA150 shown here with its companion SC22 Preamplifier, were part of the Conrad Johnson Sonographe series. Here's a good example of where I need the vintage audio community's help to supply information on these. I traded a couple of pairs of speakers for this nice set, and love the sound, but know very little about Conrad-Johnson other than the company makes quality gear.

How does it sound? Very clean, uncolored, nice with all kinds of music. Seems like many of my amps sound this way on first impression, but some - like some of my Carver models - don't retain those qualities for me as I continue to listen to them. Listener fatigue can set in early and often for me if I don't like a particular component. It happened with one of my Pioneer Elite PD-65 CD player which sounded so thin to me that it continually left me wanting more . . .notes, sound, dynamics - something! But I digress, the SA150 and the SC22 were perfectly paired, and although they didn't represent the flagship of the Conrad-Johnson line for their day, were certainly contenders for design quality and attention to what matters most - the sound.

If you have any photos, or more information on the Sonographe Series by Conrad Johnson, please leave a comment or email me.

  1. Dear collector,

    Since you ask for more information: I have a schematic of the line-level preamplifier section of the Sonographe SC-22 preamplifier. Drop me a line if you're interested, and I can mail it to you.

    Best regards,

    Aren van Waarde
