PS AUDIO STELLAR STRATA

Second-hand, in mint condition, without scratches. Supplied with accessories and original package.

Stereo integrated amplifier

This integrated stereo amplifier combines a DAC and a high-resolution network streamer, offering a complete solution for music listening. Its preamplification stage is fully balanced and operates in Class A, with direct coupling to eliminate any capacitors from the signal path, ensuring uncompromised sound purity. The volume control uses the proprietary Gain Cell system, which adjusts gain without introducing distortion, guaranteeing absolute sonic transparency. With a power output of 200 watts per channel at 4 ohms and 100 watts per channel at 8 ohms, the power stage features Analog Cell technology for powerful and detailed sound.

The amplifier also includes a dedicated Class A headphone output on the front panel and a high-quality digital-to-analog converter based on a 32-bit ESS Sabre Hyperstream DAC chip, supporting high-resolution DSD and PCM. Its digital input stage uses Digital Lens Native Mode technology and an FPGA architecture to process the signal without intermediate conversions, while the precision clock ensures minimal jitter. The latest-generation asynchronous XMOS USB processor ensures a stable, high-quality connection.

Additionally, the network streamer supports resolutions up to 24-bit / 192 kHz and is compatible with major streaming services like Tidal, Qobuz, Spotify, and more, allowing playback of music files from NAS and DLNA/UPnP network servers. Control is provided via the dedicated PS Connect app or music server software for computers.
