{"product_id":"borderpatrol-se-i-spdif-tube-dac","title":"BorderPatrol SE-i SPDIF Tube DAC","description":"The BorderPatrol DAC SE-i SPDIF features a vintage Philips TDA1543 16-bit R-2R non-oversampling DAC chip, a coaxial S\/PDIF input supporting PCM up to 24-bit\/96kHz, and a copper chassis with an aluminum front panel. Designed to restore analog soul to digital music, it eliminates digital filtering, upsampling, and active output buffering in favor of direct signal paths with Jupiter beeswax film-and-foil output capacitors. Its defining feature is a hybrid power supply built with twin transformers, a high-inductance choke, and a switchable EZ80 rectifier tube. Users can toggle the tube via a front-panel button, altering power delivery to adjust harmonic weight and spatial bloom.\n\nCritical consensus praises this converter for delivering a remarkably natural, organic soundstage that frees digital playback from grain and fatigue. Publications such as The Sound Advocate and The Audio Beatnik applaud its lush midrange, rich tonal density, and realistic instrument placement. Reviewers highlight that engaging the switchable tube rectifier adds tactile body and analog-like flow without softening dynamic impact.\n\nIntegrating this converter into your system brings vinyl-like fluidity and emotional depth to high-resolution digital audio. By uniting classic R-2R processing with an advanced choke-input power supply, it transforms digital streams into a deeply immersive, fatigue-free listening experience. It stands as an ideal choice for audio enthusiasts who value rich timbre and natural musical flow.","brand":"BorderPatrol","offers":[{"title":"Default Title","offer_id":67630145896729,"sku":"100743","price":1299.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0844\/4225\/1545\/files\/100743-6.jpg?v=1790981890","url":"https:\/\/tmraudio.com\/products\/borderpatrol-se-i-spdif-tube-dac","provider":"The Music Room","version":"1.0","type":"link"}
