Theta DS Pro Prime II DAC Very good and good working order.
Condition is good, which implies a clean, reliable unit and makes the £400 asking price a standout bargain. This price sits well below the 25th percentile of £1,136 for comparable used Theta DS Pro Prime II DACs, marking it as a strong deal and genuine bargain in the current GBP market where the median is £1,435.
Theta DS Pro Prime II DACs are well-regarded for their hybrid 4x-oversampling software D/A processing and 64x-oversampling Philips Bitstream conversion, delivering exceptional sound quality from CD transports and early digital sources. Their reputation as amazing-sounding DACs, combined with the original-retail price of roughly £1,250 (converted from $1,250) and the rarity of finding one in good condition at such a low price, creates a prime buying opportunity for any enthusiast seeking high-quality vintage digital-to-analog performance.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Theta Digital emerged in the late 1980s from a research project by a group of music enthusiasts in the United States, determined to overcome the harsh sound of early compact discs. Their breakthrough came with the 1988 release of the DS Pre, the world's first DSP-based outboard digital-to-analog converter, which revealed unprecedented musical detail and set a new benchmark for digital playback. Rooted in a philosophy of non-obsolescence, the company emphasized upgradeable designs, allowing owners to evolve their systems without waste, a commitment that defined its early heritage.
The brand specializes in high-end digital audio components, particularly DACs renowned for their lifelike transparency and two-channel purity. Iconic products like the Casablanca series—starting in 1995—evolved into modular music and cinema controllers with open architecture, supporting up to 12 channels, advanced DSP processing, and bandwidths reaching 192 kHz. Under the stewardship of figures like Morris Kessler of Amplifier Technologies and engineer Dave Reich, Theta also produces elite amplifiers such as the Dreadnaught and Citadel, blending cutting-edge tech with audiophile-grade build quality.
Positioned firmly in the high-end audio market, Theta commands a cult following among discerning buyers for its uncompromising sound and longevity. Though production has waned in recent years following company changes, its legacy endures through still-upgradeable Casablanca units and a reputation for products that outperform contemporaries, appealing to serious collectors and home theater aficionados seeking timeless excellence.
