Theta DS Pro Prime II DAC In Excellent Condition

Working, Very good condition. Very nice sounding D/A converter. $1250 originally. From a 1991 Stereophile review written by Robert Harley:Parts quality is very high. The capacitors associated with the Bitstream DAC are primarily polystyrene, all resistors are 1% metal-film types, and four of the resistors in the feedback loop are $3 non-inductive wirewound types. These resistors reportedly had a huge effect on the Primes sound quality. In addition, a few Teflon capacitors (very expensive) are used in critical audio stages. The metal work is zinc over copper over steel, and the pcb is glass epoxy.MusicI could go on, but you get the idea. In short, the Primes soundstage presentation and resolution of spatial cues were rare to hear from any digital processor, never mind one that costs $1250.After getting over the Primes stunning soundstage, the next aspect that grabbed my attention was the units dynamics. The Prime presented an effortless feeling of power, allowing the musics dynamics to more fully express themselves. There was a razor-sharp edge to transients, coupled with an ability to reveal wide dynamic contrasts. The result was a sense of suddenness, immediacy, power, and life.ConclusionAt $1250, the Theta DS Pro Prime represents another significant increase in the price/performance ratio of digital processors. It clearly outperformed every processor in its price range, and rivaled those costing much more. Its overall performance was better than that of Thetas DS Pro Basic, a unit that itself brought a new level of performance to a sensible price. In fact, processors with the Primes sound and costing as much as $3000 would still receive a recommendation.The Primes strengths are many: robust and powerful bass, smooth tonal balance, and best of all, a stunning presentation of soundstage. This last quality is the Primes highlight. Its ability to reveal spatial cues within a huge, transparent soundstage was remarkable, and easily superior to processors costing many times more. Description: 4x-oversampling software-based D/A processor with Bitstream DAC. Digital filter: 4x-oversampling Theta composite filter using one Motorola 56001 DSP chip.
