Condensed high-end audio design philosophy and audio design know-hows learned from over 6 decades of our experience in a small cabinet as small as an A4-sized footprint.Features at a glanceHi-Res audio playback supporting DSD512 (22.5MHz) and PCM 768kHz/32bit PCMAn ESS Technology ES9038Q2M converter each for left and right channelsDual on-board clocks for 44.1kHz and 48kHz frequencies7 types of PCM digital filtersUp-conversion up to 24.5MHz DSD and 384kHz/32bit PCM10MHz external clock inputBluetooth® receiver supporting LDAC™, Qualcomm® aptX™ HD, AAC and SBCOriginal TEAC-HCLD2 enhanced-current output buffer circuitDual monaural circuit designDual toroidal-core power transformers for each channelTEAC-QVCS quad volume control system4.4mm 5-polar Pentaconn*1 jack and dual 1/4” (6.3mm) TRS jacks for balanced and active-ground drivesFull-dot OLED display with dimmer functionNewly-developed “Stressless Foot” design with three support pointsSemi-floating design Top PanelBulk Pet*2 USB transferring technology with four transfer modes for various sound charactersFree TEAC HR Audio Player for Windows/MacESS Technology ES9038 Q2M high-performance DAC supports resolutions up to 22.5MHz DSD and 768kHz/32bit PCMEmployed one DAC chip, which is a crucial component for digital audio, in each of the stereo channels. The ESS Technology ES9038Q2M SABRE32 Reference DAC that we use has a strong reputation in the high-end audio market.Dual monaural circuit design and fully-balanced designA dual monaural circuit configuration is used throughout, from the power supply (including power transformers), to the D/A converters in the digital section and the Analog output stage. From the high-performance D/A converters to the massive toroidal-core power transformers, each element is configured for single channel processing.High-quality wireless audio streaming via Bluetooth®In addition to conventional SBC and AAC codecs, the UD-505-X also supports LDAC™ (24bit/96kHz Hi-Res audio transmission), and Qualcomm® aptX™ HD, a codec that uses 24bit/48kHz format transmission. These allow you to playback playlists on your smartphone and tablet wirelessly.Up-conversion up to 384kHz/32bit PCM and 24.5MHz DSDEmploying RDOT-NEO (Refined Digital Output Technology NEO), a fluency algorithm that renders digital audio signals smoothly, the UD-505-X up-converts PCM digital signals up to 384kHz/32bit PCM and 24.5MHz DSD. With the up-conversion function activated, you will hear an improvement in quality, even with music that you are familiar with.Dual high-capacity toroidal-core power transformersThe dual monaural theme continues. Two over-sized high-capacity toroidal-core power transformers are employed in the UD-505-X, supplying stable, individual current sources for each of the left and right channels. This means neither channel will be affected by changes in the power consumption of the other during digital processing.Analog output circuits have been further refinedImproved TEAC-HCLD2 enhanced-current output buffer amp circuitWe employed the TEAC-HCLD 2 for the analog output circuit. This is a further improved version of the TEAC-HCLD circuit enhanced-current output buffer amp that increases crucial current output capacity (HCLD: High Current Line Driver). This model now uses line buffer ICs with extremely high current output capacity.TEAC-QVCS four-circuit-structure high-precision volume control newly incorporated for preamp circuitsTEAC-QVCS (Quad Volume Control System) is used for the volume circuit. This electronic volume control is a variable gain amp type comprised of four discrete circuits for left, right, positive and negative (L+, L?, R+, R?). By placing the variable gain amp volume control, which processes in analog, in the audio signal path on the circuit board, issues with noise resulting from diverging wiring are avoided.Designed to bring out the maximum potential of your headphonesThe UD-505-X's headphone amplifier circuit provides balanced-drive by using the TEAC-HCLD2 circuit, – comprised of four output transistors for each left and right channel – for headphone output. With challenging 600Ω high-impedance headphones for example, the UD-505-X allows you to bring out the potential of these type of headphones.Active-ground drive offers a new headphone drive modeThe active-ground is a new driving mode that employs the principles of balanced connection. It forcefully drives the ground, by lowering the ground level to 0V, providing an ideal ground condition (rather than just connecting to the conventional ground). This means it also suppresses hum noise from the power supply and enhances the purity of silent pauses by lowering the noise floor. Subtle detail, such as the breathing of artists and the textures of sounds, will feel even more convincing.Symmetrically laid out XLR and RCA output jacksThe UD-505-X is equipped with both balanced and unbalanced Analog audio outputs. A pair of XLR connectors and another pair of RCA connectors - each gold-plated - are symmetrically laid out, hinting at the dual monaural arrangement inside, and allowing a wide range of possible audio configurations.Newly-developed Stressless Foot designOur newly-developed original Stressless Foot design with three support points enables stable placement of the unit so that it is not impacted by slight irregularities in the surface beneath it. Compared to the original feet used in previous designs, these feet are only partially fixed to the chassis.
