Theta Digital Generation VIII Digital Signal Processor

Theta Digital’s Generation VIII Series 3 is a reference‑grade DAC/preamp that delivers ultra‑resolving, highly dynamic sound for serious two‑channel listening, and this unit is in used but clean cosmetic condition with no major flaws. Please note: it is configured for 230 V operation and does not include a 230 V power cord.

The Generation VIII Series 3 is a high‑end digital‑to‑analog converter and pre‑amplifier designed by Theta Digital for uncompromising audiophile systems. It combines state‑of‑the‑art DAC technology with a fully featured analog preamp stage, allowing you to connect digital sources directly to a power amplifier.

Key performance features

• 24‑bit / 192 kHz digital‑to‑analog conversion for high‑resolution audio playback.

• Up to 132 dB dynamic range, providing exceptional low‑level detail and headroom.

• Over 3x differential output current compared to earlier versions for better drive and control.

• Stop‑band attenuation of 130 dB and pass‑band ripple of ±0.00001 dB for extremely accurate signal reconstruction.

• Fully differential DAC follower op‑amp with 150 MHz bandwidth for wide, open, and stable sound.

Design and functionality

This unit incorporates four discrete analog, digitally controlled volume cards with zero‑offset nulling, giving you precise, transparent volume control from the preamp section. A new digital input card accepts up to 176.4 kHz and 192 kHz signals, making it suitable for modern high‑resolution sources. The chassis and overall build quality are substantial and engineered for long‑term reliability in demanding high‑end systems.

Condition and what’s included

This is a used Theta Digital Generation VIII Series 3 DAC/preamp in good overall cosmetic condition, showing only light, normal signs of use and presenting very well in a rack. It is the 230 V version and will ship without a 230 V power cord or remote; you will need to supply your own region‑appropriate IEC power cable and remote.
