9i-92SA III "Golden Thrush" DAC / headphone amplifier / preamplifier is a desktop hifi product for headphone user. A variety of advanced technologies and solutions such as USB isolation technology were integrated , such as ESS 9038Pro DAC chip work in eight channel parallel connection, etc.. The audio quality especially headphone amplifier performance is excellent. It will get good effect in driving the mainstream headphones such as HD800S and T1-II.
Four output modes let you select the one that best suits your listening preferences or the characteristics of your headphones. Normal mode is for low-impedance headphones and earphones, and BTL mode for high-impedance headphones. Parallel mode is effective for medium-impedance headphones, increasing driving force but not gain. Finally, Active Ground mode, which brings a stronger sense of harmonics, is particularly suited to listening to vocals or stringed instruments, thanks to the simulation of a "virtual GND". This last mode offers a softer, warmer listening experience.
The technology used in the headphone amplification circuit is fairly simple, but the extremely fine-tuned settings resulting from CEN.GRAND's know-how and experience deliver a clear, delicate sound balance. CEN.GRAND's aim here is to provide a headphone listening experience worthy of a Hifi system.
Recommended for High Impedance Headphones.
Suitable for listening to Human Voice.
Recommended for Medium Impedance Headphones.
Recommended for Low Impedance Headphones.
Within your source device, such as a computer, there may be numerous decoupled power supplies generating noise that is harmful to analog circuits. That's why CEN.GRAND has equipped the 9I-92SA III with USB interface isolation technology to block any noise coming from your source device. Isolating this noise significantly improves the purity of the sound signal. On the FGPA side, the code manages data isolation, clock distribution and DoP format decoding.
Equipped with an LPF (low-pass filter) and a high-performance AOP2604, the OPA amplifier circuit delivers a clean audio signal. The volume control chip, a PGA2311, is MCU-controlled. The volume range is -70db to 0db.
Two ESS 9038Pro DAC chip are used and one for each channel. There are 8 internal DAC in each 9038Pro chip. Most of DAC which used 9038Pro chip only use one or two of them. The others are idle. The mode of multiple DAC channel parallel has many advantages but it is not easy to get good sound and heating is serious. The 9i-92SA III is different. With careful design and adjustment, the structure of 8 internal DAC parallel is one of important reason of good sound.
The technology of headphone amplifier is actually simple and the key is adjustment. Drawing on extensive experience in hifi systems, we have achieved very good results in designing of the "Golden Thrush" headphone amplifier. It not only has strong driving ability but also sound balance, clear and delicate, strong sense of space. You can listen for a long time as well as forget the existence of headphones just like listening to the big HiFi system.
