I used to run a Marantz 8 into some highly modified Klipsch La Scala's. Their high sensitivity really helped to ease the load on the amp, allowing it to sing. Lower efficiency speakers may not be best for this amp, as they really only produce about 10 - 12 wpc RMS at low distortion levels. This is true of many other tubed amps of similar design, even though they are rated at 30 - 40 wpc.
Much of the "warmth" and "harmonic richness" that people like about tube amps actually comes from the high levels of distortion that these amps generate under load. Reducing the strain on the amp by using higher efficiency, higher impedance speakers can improve both the sonics of the system AND increase the length of life of the tubes. Sean
