I've known Cline, named by Rolling Stone as one of the "100 Greatest Guitarists of All Time," from his avantgarde ensemble the Nels Cline…
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…
Description: Solid-state stereo or mono amplifier. Power output: 60Wpc into 8 ohms, >40Wpv into 16 ohms, both channels driven, 20Hz–20kHz; in mono mode, >100W into 8 ohms, >120W into 14 ohms, 20Hz–20kHz. IM distortion: <0.2% at rated output; <0,1% at lower levels. THD: <0.2% at rated output, <0.05% at lower levels. Frequency response: 20Hz–20kHz ±0.1dB; 3Hz–100kHz +0, –2dB. Power bandwidth: 8Hz–50kHz. Hum & noise: >110dB below 40 watts. Damping factor: >150. Stability: Unconditional with any type of load, or no load. Sensitivity: 1.…
At the risk of breaking that rule, I must note that…
Well, okay, we've never received the last type of letter. But if we did, it would have to refer to Hafler's new Transnova 9500…
Nor did the 9500 shortchange other types of program material.…
The Transnova idea is conceptually elegant and not dissimilar to a push-pull tube output stage. In a conventional output stage (diagram A), the "positive" or "hot" load terminal is connected to the junction between the emitters or sources of the complementary output transistors and the ground load terminal to the junction between the ±V reservoir capacitors. In general, this point defines the ground potential or 0V and is used as the amplifier's fundamental or "star" grounding reference. The output devices therefore act as emitter or source…
The Hafler was auditioned with a variety of loudspeakers, but I spent most of my listening time with it in the company of the Vandersteen 2Ces. The preamp was the Rowland Consummate. Comparison amplifiers included the Aragon 4004 Mk.II, Sonic Frontiers SFS-80, and Krell KSA-250.
The CD transport was either the belt-drive C.E.C. imported by Parasound or the Pioneer Elite PD-65 used as a transport (the latter used primarily when the Wilson WATT/Puppies or the Apogee Stages were in the system), used to drive a PS Audio Ultralink via Kimber AGDL. The…
