For sale is my Stax SRM-D10 and SR-003 Mk2, both were purchased at the end of 2022 on eBay. Im selling because I no longer require a portable electrostatic setup. They are both in very good condition and functioning properly. SRM-D10 is a portable electrostatic amplifier with built-in DAC (ESS9018), that works with Stax Pro Bias earspeakers. Accessories includes two USB cables, one 3.5mm interconnect, charger, and various plugs for the charger. Original packaging is included. SR-003 Mk2 is a portable earspeaker, comes with a headband as an accessory. I have misplaced the original silicon tips, but I am including a set of unused Sennheiser IEM tips instead (medium IE80 tips if I remember correctly). Original box is also included.

Japanese, uncompromising DAC with the best in the world and the best gradation of 2 PCM63P-K converters. Analog playing, fantastic sound. The housing has no scratches, Unrepaired and unmodified, Normal 0 21 false false false FR X-NONE X-NONE The STAX DAC TALENT version BD was battery packed and of course free from current fluctuation. This second version is much more difficult to find. The DAC-Talent BD is a compact D/A converter in which we have utilised all our experience obtained during the development of the DAC-X1t. A high quality 20-bit D/A converter is used on each channel in the Sign-magnitude configuration. This ensures no zero-cross distortion or zerocross noise is produced. A double phase locked loop circuit lock on to the incoming digital signal which can have a fs of 33kHz, 44.1kHz or 48kHz. Electrical or optical connection is possible. Facilities include an optical/electrical input selector, absolute phase switch, and an automatic sampling frequency display. STAX is planning to produce a range of similar high quality/small size audio products It’s fair to say that when STAX launched their two DACs, it was totally unexpected. First to STAX decided to build a cheaper model, and that was the DAC-Talent and DAC TALENT BD Sensibly in my view, STAX concentrated on the sound of this unit and not the cosmetics. The DAC-Talents case is workmanlike and well-finished in a silver lustre – but is nowhere as magnificent as it’s vastly more expensive companion. When we used it in the early 1990s partnered with the transport sections of stand-alone CD players that had digital outputs, it produced a more musically satisfying sound, more believable reproduction The overall improvement to CDs and transports of that era, such as Teac and Meridian when partnered with the STAX was that the sound became more vivid, more alive and compelling.
