Up for sale is my THETA DIGITAL DSPRO GEN Va with UPGRADED HARD WIRED POWER CORD! UNIT IS IN PERFECT WORKING ORDER! RETAIL ON THIS IS $6500.00!
This was upgraded at the Theta Digital factory from a DS PRO Gen III to a DSPro GEN Va model with optional xlr's.
I am listing this as Good condition as there are a few light superficial marks on face and cover.
Here, in Theta's own words, is what defines A-status:
"The analog section of the Generation Va contains 52 transistors. Through a laborious process, six matched octal sets (totaling 48 transistors) plus the remaining four uncritical transistors are now installed in every analog board. This matching process includes testing tens of thousands of devices and then hand selecting the ones that meet stringent criteria. The result of this work is a sweeter, more detailed presentation and less listener fatigue.
"In-depth research into analog filters has also wrought surprising improvements. In a digital-to-analog converter, it is imperative to filter out the sampling and higher frequencies from the analog output. Our previous designs have implemented inductors to achieve this effect. Recently, we found that the elimination of the inductors improved sonics as long as the filtering was properly performed. New filter topologies that are just as effective at eliminating the sampling frequency yet do not utilise inductors were created. Wima capacitors were found to be complementary to the new filter topology. The sonic improvements are not subtle. Less sibilance, tighter image focus and better tonal quality are immediately apparent.
"Theta Digital has always been at the forefront of jitter-reduction technology, the first implementation of which occurred in the original DS Pre. From that time on, we have continued our research into the effects of jitter and the meaning of lower jitter specifications to reproduced sound. A PLL works by continuously comparing an input signal (in this case the word clock which has been extracted from the SPDIF data stream) to a controllable oscillator's output and then producing an error signal which corrects the oscillator's frequency to precisely match the incoming signal. Some of the timing errors (jitter) present in the incoming data stream are always 'passed through' the correction part of the circuit and, as a result, adversely effect the oscillators output. The trick in PLL design is to minimize these jitter effects while allowing the correction part of the circuit to perform properly. A result of our more recent research into this area is the third part of the 'A' improvement. A more seamless sound, along with more detail are the most obvious improvements that come with the new PLL.
"The final part of the 'A' version of the Generation V is a new algorithm. Approximately two years ago our algorithm designer proposed the idea of adding dither to the program run in the Gen V. This, he proposed, would make the D/A converters operate in a more linear fashion at lower levels. Since that time, continuous listening tests based on dither variations have been conducted. The product of those tests is the new algorithm. Better low level resolution and better decay are clearly evident with the new program."
The move from Gen V to Gen V A is not a subtle, minor refining of a great product. It actually warrants calling the machine Pro Gen VI. The price increase makes the single-ended version a 4300 purchase, the balanced edition a cool 6500, but this is reflected in performance which leads me, for one, to regard the Theta as among the very best standalone converters on the market.
What the 'A'-status Pro Gen V does is improve the coherence, the seamlessness, the 'wholeness', without compromising any of the machine's other virtues.
