Ensemble, assemble!
Apos Ensembles are like the Avengers of audio gearābundles assembled by our team Ā to save your ears from the forces of mediocre sound. Every piece of equipment plays its part to deliver an unbeatable listening experience: a DAC to decode the 1s and 0s, an amp to power up the audio, and all the interconnections necessary to bring the team together.
Meet the TOPPING-90 Series Ensemble
The Apos TOPPING-90 Ensemble is a bundle designed to provide you with a premium audio setup straight out of the box.Ā
For the DAC, you have two choices. Option 1 is the TOPPING D90 III Sabre Fully-Balanced HIFI DAC, featuring dual ES9039SPRO DAC chips for exceptional audio performance with 135dB SNR and <0.000045% THD+N. It includes advanced CPLD processing for minimal jitter, Bluetooth 5.1 for high-resolution wireless audio, and versatile output modes with both XLR and RCA options.Ā
Option 2 is the TOPPING D90 III Discrete DAC, featuring a fully discrete 1-bit PSRM DAC architecture for unparalleled precision with 131dB SNR and <0.00006% THD+N. It includes ultra-low jitter (-157 dB), Bluetooth 5.1 with LDAC for high-resolution wireless audio, and versatile output options with both XLR and RCA connections.
For the amp, you'll receive the TOPPING A90 Discrete Headphone Amp, featuring an NFCA module with a powerful output of 9800mW x2. It supports both balanced and single-ended headphones with outputs including 4-pin XLR, 4.4 balanced, and 6.35mm SE. The amp also includes features like an R2R volume control, ground loop noise terminator, and a 12V trigger interface for seamless integration with either DAC.Ā
