What moves the price
- Transformers. Our own custom transformers, wound in Thailand, keep the Essential series and the lower end of each range affordable. ISO/Tango, Tamura and Muse Coils sit at the upper end.
- Output tubes. A pair of premium 300B or rare NOS tubes can cost as much as the chassis.
- Separate power supply. A second chassis lowers noise and adds cost.
- Wood and finish. Kamagong, ebony and mabolo cost more than walnut or teak.
- Options. Meters, remote volume, extra inputs, MC step-up.
