I measured the Rogue Audio RP-1's electrical performance with my Audio Precision SYS2722 system (see the January 2008 "As We See It").
The RP-1's phono input appears to use ultra-low-noise LT1115 op-amp chips. I left the internal settings as used by Herb Reichert for his auditioning— high gain and a 300 ohm load —which resulted in a voltage gain of 65.1dB at the main outputs with the volume control set to its maximum, and 55.2dB at the fixed output jacks. This is a little lower than the specified 60dB for moving-coil cartridges, but the shortfall will be…
Gotcha!
Editor: At last, your fatuous pontificating has tripped you on your face!
Your anti–four-channel "editorial" in the last issue made me boiling mad. This is a legitimate advance in the audio art, and should be acknow ledged as such, particularly in a publication that purports to be in the vanguard of perfectionist-type high fidelity. Instead of citing a half-dozen reasons why it would not go over, Stereophile should have encouraged its supposedly perfectionist readers to support the new four-channel…

The SAE Mark II has, nominally, the same performance specs as the Dynaco Stereo 120, yet it costs twice as much as a factory-wired Stereo 120, and about 2½ times as much as a Stereo 120 kit. Is the SAE really worth the difference? And how does it compare with some other $400 amplifiers? Well, it all depends.
To begin with, the SAE and…
