Good condition. No box.

Product Description

The ZL-120's sonic character perfectly complemented that of the line stage. Speak about clarity and transparency to die for!. Transients were uncoiled with speed and precision. Low-level detail appeared to bubble to the surface of a recording without attendant grain or brightness. Subjective distortion levels remained low even when driven hard, always an issue with solid-state power amplifiers. Tonally, its character hovered around neutrality. This was not a romantic sounding amplifier. If your system is in need of added warmth, you should look elsewhere. If your tastes run towards a soft presentation, then you'll be disappointed. While it's possible for an extended bandwidth design such as the ZL-120 to sound smooth and refined, excessive liquidity.
Unusually for a solid-state amplifier, soundstage spatial impression was nearly 3D while image outlines were nicely fleshed out. Massed voices were readily resolvable. This was no "water color" rendition. Individual voices did not run or blend together into a homogeneous spatial blob and instead were given distinct features. And most important of all, there was plenty of dynamic propulsion. With the right speaker load, all rocket thrusters were engaged. This was no dull, polite, smooth, simply going through the motions performer. It kindled microdynamics with verve. And neither were macrodynamics a problem: it shifted gears from soft to loud with conviction, leaving no doubt about its dynamic reserve.
