This model excels in preserving the full spectrum of detail extracted from the record groove, ensuring an unparalleled listening experience that captures every nuance of the original recording.

The SUT uses a quartet of specially selected Tamura transformers with a 2% tolerance.

A wider frequency range of 10Hz-110kHz and a very low distortion of less than 0.05% in the range of 20Hz-20kHz at 1mV input are accomplished.

Short signal path, additional shielding, compact design and all the benefits of a balanced solution without unnecessary features.

Specifications:

Input impedance: 0-3 / 40 Ohms
Output impedance: 4k Ohms
Frequency response: 10Hz to 100kHz (+-1.0dB)
Chanel separation: more than 60dB (20Hz-50kHz)
Ratio: 1:36 / 1:10
Phase characteristics: Within 10° (20Hz-50kHz)

Aailable in a Silver Aluminium front panel.

The SUT offers RCA input connectivity, with outputs available in either XLR or RCA.
