Description
This eight-channel DAC bring five new digital filters – many with low in-band ripple – to the party for new flavours of sonic reproduction.
Dac Architecture of 203
ES9039Pros pack enough computational horsepower to run their 8x oversampling process in just two passes thus minimising rounding errors – an upgrade on other attempts that use a concatenation of three stacked 2x oversampling passes which compound errors.
Perfectly exploiting the dynamic range and distortion headroom these futuristic ESS DACs provide is Cayin’s implementation. An eight-channel current-to-voltage I/V conversion stage is built in to preserve the full information from N6III/E203’s digital decode.
This overbuilt stage is befitting of ESS chips that output in current for best distortion performance, and indeed more expensive players. By treating each of the eight-channel current outputs separately before stereo summing, N6III/E203 yields a small-signal stage that is transparent and, most importantly, accurate.
The stuff of legend
The sheer resolution the ES9039Pro is capable of in E203 is the stuff of legend. But in the spirit of innovation, Cayin may be the first ones to tame this chip for personal audio use, drawing upon their experience developing the wildly-popular C9II tube/solid-state hybrid tube portable amplifier.
Plenty of C9II’s feats focused on beefing up its small-signal voltage stages, where the majority of an analogue circuit’s sonic signature is shaped. Cayin focused on reinforcing the current-delivery capabilities of said small-signal stages, ultimately allowing them to drive C9II’s big discrete output transistors – and more importantly, the challenging capacitive loads they represented.
Extended high-frequency performance
Results spoke for themselves for C9II, and that’s now trickled down into N6III/E203. This module likewise overbuilds its differential, balanced small-signal stage – where E203’s sound signature is defined – packing in the venerable Texas Instruments OPA1612 that has been respected in line-stages for over a decade.
How E203 overcomes its internal lag circuit capacitance is audible, resulting in an extended high-frequency performance that enables excellent phase response in the human hearing range for realistic dynamics.
An airy, open, precise soundstage is possible as a result. Overcoming circuit capacitance also leads to voltage signals traveling through without lag behind the current, leading to a more natural sound that does not descend into harshness.
User Replaceable Audio Motherboard
Change to a New Audio System “Just Like That” Fully modularized the audio system in the DAP, a complete replacement of both the DAC and analog circuits. Increase PCB area by 31% to take the audio motherboard performance to a new height. Built-in dedicated microcontroller interacts with the 665 MCU to enable comprehensive audio adjustments and keep track of the operation status of the Audio Motherboards independently.
Enjoy the performance into a wide variety of gear
Cayin desire for you to enjoy this performance into a wide variety of gear. That’s why E203 packs a Hyper mode, where operating voltages for its power section rise above 10 volts – the headroom and linearity of its discrete output devices assured as a result.
Indeed, Cayin’s big output devices can be operated in Class AB or an optimal Class A, for sonic tweaking with your favourite earphones and headphones. Differentiating itself from its peers built with op-amps yet with inordinate amounts of gain and negative feedback, E203’s linearity remains excellent already before correction is applied, owing to its high operating voltages and bias.
Those ensure individual transistors are working in optimum condition. Distortion and noise are kept low, without resorting to the excessive use of negative feedback. Cayin designed a true-balanced differential amplifier to further improve N6III/E203’s linearity, and you can count on common-mode rejection at its best whenever you plug in via 4.4mm preserving its resolution.
