SW1X Level II + with USB Digital Analog Converter (DAC) Interesting NOS dac from boutique manufacturer in UK. High quality parts used through, reminiscent of Audio Note with quality chokes, tubes and caps throughout. Even the USB input board utilises a nu-vista style tube in the signal path. The spdif input in this dac is unbelievably good. Description: DAC II comes equipped with more sophisticated power supplies and powerful 6N6P/6N30P/5687/E182CC valve output stage with 6X5GT (or 5Y3) valve rectification. The DAC II has a similar analogue & musical character akin to DAC level I bu
Timing matters less here than the sheer price advantage: this SW1X Level II+ with USB DAC at A$4,500 is an undeniable bargain, sitting far below the 25th percentile of A$14,411 for comparable used AUD listings. While fresh market data shows similar models ranging from A$6,000 to A$38,000 AUD, this asking price is a genuine steal for a unit that originally cost A$38,000 AUD.
This SW1X DAC II variant is highly regarded for its refined R2R sound using PCM56 chips and a valve output stage that delivers perfect digital-to-analog conversion. The timing is ideal given its rarity and the fact that it was used sparingly since 2022, likely retaining original-owner quality. With no material caveats needed at this price, it represents a clear buying opportunity for any enthusiast seeking top-tier NOS performance without the typical cost.
