Ciamarasound posted a topic in General ForumDA-250 USB DAC, Class A Preamp & Headphone Amp ($2500) Luxman’s DA-250 is a Class A Preamplifer, Class A Headphone Amplifier and a USB capable Digital Audio Converter packaged in a slim & compact B4 form factor. It delivers a wonderfully musical rich tone that will provide countless hours of fatigue-free listening enjoyment. The DA-250 is the successor to the DA-200 which launched in 2010 and proved tremendously popular among desktop audio users. Luxman’s sales team and engineers have continuously listened to end users’ comments carefully and exchanged opinions about applications and styles on how best to enjoy computer audio. Now Luxman is introducing this new USB D/A Converter DA-250 which is much improved over the DA-200 by focusing on upgrading its sound quality and adding new features and incorporating the latest technology. Digital Circuit USB input is compatible up to 192 kHz/32bit PCM data and DSD data (2.8MHz and 5.6MHz). S/PDIF input handles up to 192 kHz/24bit PCM signals. In addition to USB input, the DA-250 has a coaxial input and two optical (Toslink) inputs to enable connection with a CD player and / or DVR, satellite radio etc. The Texas Instruments PCM1795 was selected for the DAC, which contains a 32 bit digital filter, digital signals are up-converted internally to 352.8k or 384kHz/32 bit. Two different kinds of tone filter setting are provided and switchable to your taste (32bit digital filter for PCM and analog FIR filter for DSD). Low phase noise clock modules are mounted independently on both 44.1 k and 48kHz channels to reduce noise around the oscillating frequency and to generate highly accurate low jitter clock signals. By using asynchronous communication for the USB input and a DAIR high accuracy clock for S/PDIF, low jitter reduction is possible. Analog Circuit The configuration of D/A converter and high quality pre-amplifier circuit has been considerably upgraded in terms of both sound quality and performance. Output signal can be selected between Fixed and Variable modes. Variable position is convenient for a direct connection to a separate type power amplifier or a powered speaker system. For example a matching LUXMAN M-200 stereo amplifier can be used to drive the loudspeakers of your preference. Analog Input / Vinyl Recording One analog input is available. Analog signals are converted into the digital realm by way of a built-in A/D converter TI PCM9211/DAIR. For example, the matching Luxman E-200 / 250 phono stages will allow a turntable to be connected to the DA-250 and output to 24/96 for easy recording. The power environment of high inertia from a large power transformer to large capacity block capacitors and each circuit’s independent regulator is designed to provide a great drive impetus to the signal output, delivering large dynamic swings and maintaining image specificity across the sound-stage regardless of the listening level.
