The RT-5000 from Roseselsa is a DAC and amplifier for headphones using a pair of SABRE ES9038Pro chips and JRC MUSES01 transistors for digital/analogue conversion up to PCM 32bit 384kHz and DSD256 and an output power of 1600mW at 32Ω. These top-of-the-range components ensure quality sound reproduction that's both warm and soft, all housed in a beautiful enclosure.
The RT-5000 features two ES9038Pro DAC chips using HyperStream II technology to deliver exceptionally accurate, jitter-free conversion. Thanks to ESS's SABRE chips, the RT-5000 is capable of supporting a high-resolution stream of up to 32bit 384kHz PCM and DSD256 while boasting a signal-to-noise ratio (SNR) of 125dB and a harmonic distortion rate (THD) of -112dB.
The RT-5000 also incorporates a total of 10 Texas Instrument OPA1612s. Eight of these are responsible for the I/V circuit and the remaining two act as LPF amplifiers, perfectly complementing the ESS DAC chips to produce HiFi sound reproduction with ultra-low distortion and impressive dynamics.
The RT-5000's amplifier stage is based on a pair of J-FET JRC MUSES01 transistors capable of delivering 1600mW of power at 32Ω balanced and 800mW at 32Ω single-ended. This top-of-the-range pair of transistors delivers warm, smooth sound with powerful bass and a wide soundstage.
To provide high-quality Bluetooth connectivity, the RT-5000 is equipped with Qualcomm's QCC5125 chip, which supports the high-definition LDAC, aptX Low Latency and aptX Adaptive protocols.
Furthermore, in addition to its excellent sound, the RT-5000 is as pleasing to the eye as it is to the ear. Its chassis skilfully combines a CNC-machined aluminium structure with a wooden front panel, leather covering for the upper part and gold plating for the interactive elements, offering a finish that is both classy and elegant.
