A wonderful amplifier that provides the
strengths of both tube and solid state products: 3-D sound-staging,
holographic imaging, and the beautiful midrange of tubes, combined with
sparkling highs, low distortion, bass resolution, and control of solid
Conservatively rated as an 8, no marks on this amp - it looks perfect.
This unit was purchased as a KWA-150. I had it upgraded to the 150 SE configuration in Aug 2012. This upgrade is significant and includes:
- Upgraded model of Lundahl input transformer for improved speed and dynamics.
- Circuit design revisions to input circuits that lower distortion and improve dyanmics and resolution.
- Cryo-treated, solid core ultra-pure input wiring and 12GA stranded audio-grade output signal wire to binding posts.
- Revised capacitor bank (current storage design) that increases
total storage (capacitance) and also lowers power supply impedance,
which translates to faster current delivery to the output stage.
This amp is now my backup amp and hasn't been used for the last 15 months. Prior to listing it for sale, I sent it back to factory for a checkup and at that time the hi/low bias circuit was updated to the latest configuration. This amp is in perfect condition.
Used in a smoke, pet, and kid free dedicated music room.
Lots of reviews on-line that describe the performance - all very positive.
