Oriolus 1795MKII AL A refined evolution of the Oriolus 1795MKII, optimized for portable listening The Oriolus 1795MKII AL is a refined version of the acclaimed Oriolus 1795MKII, known for its mature, whisky-like tonal character. Designed with greater portability and improved synergy with modern in-ear monitors (IEMs) in mind, the AL version revisits the chassis, output stage, and overall ergonomics while preserving the musical character that made the original so highly regarded. Where Industrial Design Meets Mature Tuning The 1795MKII AL combines a calm, understated appearance with a warm matte-metal finish, blending traditional craftsmanship with modern precision. While retaining the design philosophy of the original model, it incorporates updated circuit technologies to achieve a smooth, spacious, and natural presentation. Output performance has been optimized specifically for IEM use, delivering up to 228mW of power while maintaining excellent control and low listening fatigue. The result is a sound that feels both energetic and effortlessly natural. Refining the Legacy of the PCM1795 At the heart of the 1795MKII AL is the renowned PCM1795 DAC, a chipset that has been featured in numerous respected audio products over the years. Because the PCM1795 utilizes a traditional differential current-output architecture, the surrounding analog circuitry plays a significant role in shaping its sonic character. This allows engineers considerable flexibility in tuning and optimization. Over several years of development, Oriolus carefully refined the power supply layout and analog stage while preserving the analog-like musicality that listeners have long appreciated. Building upon the foundation established by the original Oriolus 1795, the AL emphasizes tonal richness over analytical presentation, featuring a subtly warm midrange, well-defined imaging, and a quiet background that enhances the sense of space and natural density in music. The result is a balanced sound that remains engaging across a wide variety of genres without becoming overly colored. Bluetooth Processing with AK4137EQ Upsampling The integrated AK4137EQ sample rate converter operates using its own dedicated clock reference, helping maintain timing accuracy during digital signal processing. Bluetooth audio signals are upsampled to PCM 24-bit / 192kHz through high-precision filtering while helping reduce clock-related artifacts that can affect signal integrity. In the 1795MKII AL, the signal path surrounding the AK4137EQ has been kept as short as possible to minimize susceptibility to external interference. This approach contributes to a clean, extended frequency response, a quiet background, and a smooth presentation of detail. Notes emerge naturally and decay gracefully, making long listening sessions comfortable while preserving resolution and musical nuance. XMOS XU316 USB Receiver The 1795MKII AL employs the XMOS XU316 USB receiver for stable connections with PCs, smartphones, and other digital sources. Its multicore architecture provides the processing power necessary for high-resolution audio playback, while dedicated voltage regulation for the digital processing section helps maintain stable operating conditions. Combined with careful attention to timing accuracy and the implementation of the CG5125 power management solution, the design helps reduce digital power noise and supports a cleaner, more transparent listening experience. Powered by Qualcomm QCC5125 Wireless connectivity is handled by the Qualcomm QCC5125, a Bluetooth audio SoC featuring dual-core CPUs and dual-core Kalimba DSP processors. Its processing architecture helps ensure stable wireless transmission, low latency, and smooth transient response. Enhanced internal clock management contributes to a more coherent soundstage and a quieter background, allowing finer details to emerge naturally. The 1795MKII AL supports major Bluetooth codecs including SBC, AAC, aptX, aptX Low Latency, and aptX HD. A large antenna design provides reliable wireless performance with a transmission range of approximately 10 meters in unobstructed environments. Precision Engineering Designed for Everyday Carry The aluminum chassis features a bright yet refined appearance, complemented by a semi-transparent glass panel that subtly reveals the internal architecture. The seamlessly integrated glass panel is smoothly rounded along its edges, enhancing both comfort and visual cohesion. The aluminum surfaces receive a finely brushed matte finish, creating a warm tactile feel while maintaining the precision expected from a dedicated audio component. The result is a design that feels equally at home on a desktop or in a daily carry setup. Tuned for Everyday Listening Whether commuting, working, or relaxing at night, the 1795MKII AL is designed to fit naturally into everyday listening situations. Bass is controlled and articulate rather than exaggerated. The midrange offers natural density without becoming intrusive, while the treble remains smooth and extended without sacrificing information. The tuning is approachable for newcomers yet rewarding for experienced listeners, making it a companion that can be enjoyed for hours at a time. Designed for Up to 8 Hours of Playback By carefully balancing power efficiency and output performance, the 1795MKII AL provides up to 8 hours of continuous playback, allowing users to enjoy music confidently throughout the day. Lightweight Aluminum Frame To improve portability, the chassis utilizes aluminum with excellent thermal conductivity. This allows heat generated within the device to dissipate efficiently while keeping overall weight low. The result is a portable form factor that balances everyday practicality with the stability expected from a precision audio device. Some product images may depict the original 1795MKII model.
