The KWA 100 provides the strengths of both tube and solid state products: 3-D sound-staging, holographic imaging, and a beautiful midrange of tubes, combined with sparkling highs, low distortion, bass resolution, and control of solid state.

The heart of the KWA 100 Amplifier is a single voltage gain stage called the "Solid State Music Stage." The circuit was developed by Alan Kimmel, creator of the exceptional vacuum tube "Mu" stage.

Mosfet output stage design.

Features include: high-low bias switch, and true balanced floating inputs, accepting balanced and unbalanced inputs. The design incorporates a regulated power supply for the input stage, and oversized heat sinks. The first watts operate in pure Class A.

The KWA 100 uses no global feedback, is direct-coupled, fully differential, and designed and Handmade in the USA.

Specifications:

• Dimensions: 17"Wx17"Dx6"H;
• Weight 47lb packed.
• Power: 100W @ 8ohms; 200W @ 4 ohms.

• High / Low bias switch
• True balanced floating inputs,
• XLR and RCA Inputs
• Regulated power supply for the input stage

Six tubes are used in the PS 36.5: (2) 6H30 triodes for signal gain and buffering, (2) 6EA7/6EM7 triodes for voltage regulation and (2) 5AR4 (and equivalent, including 5U4) for rectification, making this power supply a true dual mono design.

Existing LS 36.5 units can be upgraded or the two box preamplifier can be ordered as a LS 36.5 DM.

We feel this new upgrade offers a substantial breakthrough in value and performance. The PS 36.5 is styled to match the LS 36.5 and rectifier tubes are exposed to allow ease of tube replacement.

The heart of the KWA 150 Amplifier is a single voltage gain stage called the "Solid State Music Stage." The circuit was developed by Alan Kimmel, creator of the exceptional vacuum tube "Mu" stage.

Features include: high-low bias switch, stereo/bridge-mono switch and true balanced floating inputs, accepting balanced and unbalanced inputs. The design incorporates a regulated power supply for the input stage, Cardas' best connectors and oversized heat sinks. The first watts operate in pure Class A.

The KWA 150 uses no global feedback, is direct-coupled, fully differential, dual-mono, bridgeable, and designed and built in the USA.

Specifications:

Dimensions: 17"Wx17"Dx9"H;

Weight 84lb packed.

Power: 150W @ 8ohms; 250W @ 4 ohms; 450W @ 8 ohms bridged mono; 650W @ 4 ohms bridged mono.

All power ratings at .05% THD!

Noise Floor: -100dB (Unweighted)

Bandwidth: 10Hz - 100Khz (+0, -1dB)
