Superb Sounding DAC; Has Balanced, and has 3 switchable inputs (switch on front); Great feature. Beautiful face. I regard the Generation V as one of the best five or six digital processors Ive heard—and most of the others cost much more than the Theta. The Gen.V is a must-audition for anyone looking for the best in digital playback. Robert Harley From a Stereophile review written by Robert Harley and Shannon Dickson:The Gen.V is an evolution of Thetas highly regarded DS Pro Generation III processor. The V uses the same DSP engine for the digital filtering, and even the same filtering algorithm. The big differences in the Gen.V are the all-discrete analog output stage (no op-amps, as in the Generation III) and the updated power supply.The Gen.Vs build is almost unique. The unit is divided into three distinct sections, each shielded from the other: the power supply is housed in a subchassis below the digital section and the analog output stage, and the digital compartment occupies about two-thirds of the upper area. These subchassis act as Faraday cages to isolate each subsystem from the others electromagnetic radiation.The power supply has four separate power transformers supplying 13 regulators. Eight of the power-supply rails are regulated in the power supply, then re-regulated on the analog board next to the circuits they supply. All the regulators in the Gen.V are three-pin ICs; filter capacitors are the excellent Nichicon Muse types. The power supply of the Gen.V was significantly updated from that in the Generation III, to accommodate the new discrete output stage.ConclusionThe Theta DS Pro Generation V—which provides a major improvement in sound quality over its predecessor, the Generation III—represents a sonic turnaround for Theta, with less of a distinctive character. The smoother, more laid-back Gen.V resolves more detail than, and has a refinement lacking in, the Gen.III. While making their top-of-the-line processor less vivid and incisive, Theta managed to maintain the hallmarks of their products: spectacular soundstaging, the best bass reproduction in digital playback, and a wonderful sense of pace and drive.Specifications:Description: DSP-based D/A converterDigital inputs:One AES/EBU, one coaxial on RCA jack, one coaxial on BNC jackDigital tape loop:One, on RCA jacksFactory Optional digital inputs (1992 Pricing)AT&T ST-type optical ($300), Thetas LaserLinque optical ($800), TosLink optical ($100)Digital filter:8x-oversampling, custom-software–controlledComputing power:129 effective MIPSMathematical resolution:56 bitsOutput resolution:20 bitsLinearity:20 bitsFrequency range:1 Hz – 21 kHz (no tolerance given)S/N ratio:>108 dBTHD at full output:<0.002%Balanced output level:5V RMSUnbalanced output level:2.5V RMSOutput impedance:26 ohms (balanced); 1 ohm (single-ended)Dimensions:19 W by 3.5 H by 13 DWeight:35 lbPrice:$3795 (single-ended), $5595 (balanced)

I am selling this as ***Parts Or Repair Only***This THETA DIGITAL DS-PRO GENERATION V Upgraded version is in working condition but it has some noise in one channel. I contacted Theta and they recommended George Meyer Audio in California for the repair and if it Doesnt sell here thats were it will be headed. Thanks for looking

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.
