For sale is a Theta DS Pro Generation III digital processor in good condition. This DAC has been recently serviced and new electronic components put in such as 2 toggle switches, a capacitor, and a resistor. Our tech has confirmed this piece is in great working order and sounding awesome. Cosmetically there are some blemishes like edge wear on the front face and sides of the unit. There is also some marks on the top plate of the DAC and the rubber of the power cable has some tears in it. All of these blemishes have been showcased in the photos. Although these piece has some obvious signs of use, it is still 100% functional and sounding absolutely incredible. The Theta DS Pro Generation III is a superb product worthy of my highest recommendation. Listening through it, I consistently crossed the threshold from good sound to total immersion in the music. This was digital playback of the highest caliber. Moreover, the Gen.III had much less of a distinctive signature than previous Theta processors, with a smoother treble, better portrayal of instrumental textures, and a more refined, yet bigger, soundstage. In addition, the Gen.IIIs bass performance—extension, control, power, and warmth—was beyond reproach. - stereophile.com SPECIFICATIONSDescription: Solid-state D/A processor.Frequency response: DC–21.72kHz (no tolerance given)Decoding software: proprietary time- and frequency-domain optimizationMath resolution: 56 bitsComputing power: 45 MIPS (million instructions per second).Inputs: four coaxial on RCA jacks (Toslink and AT&T ST-type optical inputs optional)Digital output: one RCA jack, S/PDIFAnalog output: Single-ended on RCA jacks, 3.4V minimum at full scale (balanced on XLR jacks optional)S/N ratio: 120dBResolution: 20 bitsLinearity: 20 bitsTHD: 0.002% at full scaleOutput impedance: 2 ohmsDimensions: 19 W by 15.5 D by 3.875 H.

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.
