Echo's End Supreme Edition

About the Echo's End Supreme Edition

The LessLoss Echo's End Reference Supreme Edition is a premium discrete precision resistor R-2R ladder DAC designed for audiophiles seeking the utmost in digital-to-analog conversion fidelity. It features two separate Panzerholz enclosures—one housing the power supply and the other the DAC circuitry and additional Firewall modules. The unit employs dual transformers, with one dedicated to the digital input schematic, both potted in a special high negative ion content epoxy compound to reduce noise. It includes additional power stabilizer schematics providing 30 times dynamic headroom for the digital input section. The DAC uses three grounded custom handmade carbon fiber transformer shrouds to significantly lower the noise floor and improve jitter reduction. The power inlet is cryogenically treated, solid copper, and gold plated, contributing to a smooth and dynamic sound. The design incorporates three separate LessLoss XLR DC cables based on triaxial cable to connect the two units. It uses the most precise resistors available and dual power supplies with dual Soekris boards reprogrammed for dual mono operation, enhancing stereo separation and spatial nuance. The balanced XLR output is derived from four mono channels of resistor ladders with output buffering bypassed, resulting in digitally perfect balanced signals with extremely low noise floor and holographic sound. The DAC includes a custom LessLoss S/PDIF to I2S conversion schematic superior to the Soekris onboard solution, automatic digital input selection, and a unique 3.3V generation for internal I2S power supply, discarding the USB 5V supply for improved stability and smoothness. All floating bolts and housing bolts are point-to-point star grounded to minimize internal noise reflections, and the unit integrates 14 Firewall 64X technology modules, the best ever made by LessLoss, to ensure ultra-low noise and high stability at very high frequencies. It supports PCM audio up to 24-bit/192 kHz and DSD 1x and 2x over USB input. The DAC is housed in solid Panzerholz enclosures, known for their acoustic properties, and ships in a branded water-tight flight case. This DAC is noted for its smooth, dynamic, and holographic sound with exceptional clarity, transparency, and spatial depth, making it suitable for discerning listeners who prioritize analog-like musicality and minimal digital artifacts.
