1795MKII

The "1795MKII" will appeal most to those who have a long-standing relationship with music.

【Oriolus 1795MKII】
A portable DAC that combines old and new technologies, prioritizing a calm and refined sound over flashiness. It is a subtle and meticulously crafted model for those who want to quietly engage with music in their daily lives, or those who prefer a calm sound that is less fatiguing for extended listening sessions.

“Quietly housing matured music”
Its calm presence and the premium quality of its metal materials convey a fusion of old and new the moment you pick it up. The 1795MKII is a model whose sound direction is determined by this impression. It combines classical design philosophy with modern circuit technology, pursuing a matured sound that you’ll want to listen to for a long time.

“PCM1795: Refining the Origin”
The 1795MKII features the PCM1795, which has been adopted in many famous audio devices. The sound quality of traditional differential current output is heavily influenced by surrounding circuit design, allowing engineers a wide range of tuning possibilities. Through several years of meticulous adjustment, focusing on power supply layout and the analog stage, we preserved the familiar analog-like texture while aiming for a natural sense of density that resonates with the listener's ears. This is achieved by combining a rich sound with a subtly warm midrange, clean contours, and a quiet, deeply sinking background, all while maintaining the acclaimed resolution from Oriolus' first 1795. The charm lies in its matured characteristics, which don't lean too heavily on texture and gently settle any piece of music.

“AK4137EQ Upsamples Bluetooth Input”
The built-in AK4137EQ is a sample rate converter that operates based on an internal oscillator and adopts an independent clock configuration to suppress timing fluctuations during resampling. It upsamples audio signals input via Bluetooth to PCM 24bit/192kHz through a high-precision filter, while simultaneously reducing clock-derived noise components, including jitter. In the 1795MKII, the signal transmission path around the AK4137EQ is designed to be as short as possible, suppressing the influence of external noise. This achieves a sound that combines clear extension with minimal distortion at the edges of the frequency band and a quiet background. The sound image rises smoothly, and the reverberations naturally fade away, aiming for a resolution and detail expression that is less fatiguing for long listening sessions.

“XMOS XU316 USB Receiver”
The XMOS XU316 is adopted to provide stable connectivity with PCs and smartphones. Its high-speed processing, thanks to its multi-core configuration, contributes to stable transmission even for high-resolution audio sources with large amounts of information. Independent regulators are placed in the digital processing section to suppress voltage fluctuations caused by load changes in the USB section, thereby stabilizing the timing processing within the XMOS. The design considers jitter suppression, and the power supply system is equipped with the CG5125. By reducing power supply noise in the digital processing system, the purity of the signal is maintained, supporting a quiet background and the reproducibility of fine details.

“Adopts QCC5125 for powerful stability”
The Qualcomm QCC5125 is a multi-core Bluetooth audio SoC combining a dual-core CPU and dual-core Kalimba DSP. It stabilizes signal processing during wireless transmission, contributing to low latency and smooth sound onset. By enhancing the accuracy of internal clock management, it suppresses processing irregularities and the effects of unnecessary noise, achieving reproduction where the soundstage clarity and background quietness are easily perceived. In addition to major codecs such as aptX, aptX HD, aptX LL, AAC, and SBC, it is designed to widely support other codecs for high-quality audio playback. The adoption of a large antenna ensures a stable connection of approximately 10m in an environment without obstacles.

“An appearance reminiscent of Old Money”
Subdued coloring and elegant lines, understated yet refined.
The metal frame design embodies a sense of calm, like a tool whose impression doesn't change with time. The combination of integral molding by CNC stainless steel and semi-transparent glass with rounded edges is naturally accepted as a personal item, aiming for a texture that can be used and cherished for a long time.

“Sound that blends into every aspect of daily life”
Sound production designed to accompany various scenes, from commuting and work to relaxing at night. The low frequencies don't rely on sheer quantity but adopt a tight and deep characteristic. The mid-range has a gentle density that is not taxing on the ears, and the high frequencies, while rounded at the edges, extend without losing information. It’s a straightforward tuning that feels natural even to first-time users, allowing for a long and enjoyable shared experience.

“Designed for 8 hours of continuous playback”
Balancing power saving with output performance, it ensures stamina that prioritizes ease of handling. Specifications allow you to concentrate on music with peace of mind even outdoors.

“Reinforced exterior frame”
The metal frame is designed to ensure durability while avoiding excessive weight. It is impact-resistant and suppresses unwanted internal resonance, contributing to stable operation and preventing accidental degradation of sound quality. Its robust construction for long-term use provides peace of mind.
