Most of these types of ASR threads are largely pointless, other than an opportunity for objectivists to vent their frustrations with audiophiles.
If you want to make a difference, come help out on r/headphoneadvice. It already very much leans objective when it comes to amps and dacs. There are a lot of people new to the headphone hobby asking advice about amps and dacs who can be persuaded to listen to reason.
Similarly at r/budgetaudiophile when it comes to speaker equipment.
In other words, the amount of energy expended here on hwest could have persuaded several people to avoid the audiophile alternate reality. It's much more productive to build a new generation of audio enthusiasts who understand the value of measurements and the problems with perceptual bias. Rather than arguing with those who drank the Kool-Aid a long time ago.
Undoubtedly some of the majic happens here but I can't find all the measurements details online or I would provide them.
Independent Power Supplies: The Onkyo AV preamplifier employs A massive toroidal transformer with separate EI transformers for audio/video processing.
Advanced Circuitry: The Onkyo PR-SC5530 AV preamplifier incorporates a variety of advanced circuitry to eliminate jitter & distortion for cleaner, clearer sound reproduction.
- VLSC (Vector Linear Shaping Circuitry): Conventional D/A conversion methods reduce digital pulse noise at the conversion stage, but can't remove it completely. Previously only found on higher-end components, VLSC (Vector Linear Shaping Circuitry) employs a unique D/A conversion circuit to overcome this problem. Data is converted between sampling points and these points are joined with analog vectors in real-time to produce a smooth output wave form. The result is a virtually noiseless, smooth analog signal based on the digital source to bring out even the most subtle of nuances in your music, movie soundtracks, and even MP3.
- PLL (Phase Locked Loop) Jitter-Cleaning Circuit Technology: PLL jitter-cleaning circuit technology reduces jitter by comparing the input and output phases of the digital signal and creating an accurate clock waveform. This enhances the precision of digital signal processing and noticeably improves audio quality. Jitter-cleaning technology works both for digital signals input via HDMI and for digital signals converted from analog signals inside the preamplifier itself.
- Linear Optimum Gain Volume Circuitry: Linear Optimum Gain Volume Control adjusts the gain so that less than half the amount of attenuation is needed, ensuring the signal never comes close to the noise floor. This protects the signal against noise, resulting in a dramatically clearer sound.
32-Bit DSP Engine & DACs: The Onkyo PR-SC5530 AV preamplifier employs dual 32-Bit digital signal processing and utilizes seven discrete 32-bit TI Burr-Brown DACs for optimum performance.
- Dual 32-Bit DSP Engine: The Onkyo preamplifier is equipped with a powerful and highly accurate dual 32-bit DSP (Digital Signal Processor) for better surround sound reproduction.
- 32-Bit TI Burr-Brown DACs (Digital-to-Analog Converters): This preamplifier is equipped with seven discrete 192 kHz/32-bit TI Burr-Brown digital-to-analog converters to decode & playback high-resolution recordings with less jitter and clearer sound. These next-generation DACs employ an advanced Texas Instruments (TI) architecture to achieve excellent dynamic performance & improved tolerance to clock jitter.
Immersive Surround Sound: The Onkyo PR-SC5530 AV preamplifier goes beyond regular surround with the latest immersive surround sound formats, like Dolby Atmos & Dolby Surround.
