Mint condition, black, with box
Against the recent GBP comps, £890 lands just under the £891 25th percentile and below the £892 median, so this is a slight-to-solid deal rather than merely fair. It is not a massive outlier, but it is priced at the friendly end of the market for this piece.
That makes it appealing if the unit is genuinely clean, because Theta Digital gear is generally valued for serious digital performance and long-term usability. For a buyer, the main upside is getting a respected, audiophile-grade digital component at a price that avoids the usual premium; I’d simply confirm it powers up properly, reads discs/files as expected, and that any remote, transport, or interface bits are present and working.
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.
