For sale as a unit, because that is the way these should be sold, is a Theta Data Universal Tansport and a Theta DS Pro Prime Digital Audio Processor. They are a great component CD player.For 40 years I have been a serious audiophile. I have always preferred tubes (Audio Research SP10 Pre-Amp and Classic 60 Amp) and vinyl (Linn Sondek table with an Ittok arm and Trioka cartridge). I love beautiful mellow sound (I used Quad ESL 63 speakers). When it was... time in the mid 90s to go digital, after listening forever, I chose the Theta Data and Theta DS Pro Prime digital audio processor that are for sale today. These were my choice because they sound like vinyl. They make beautiful soft gentle music, wide open in the mid-range and with a sound stage that takes you to the live theatre. I have never regretted my choice, but over the last 15 years have not played them much. I am 72 and have sadly sold most of my stereo. It is now time for these special pieces to go.I do not have to describe them too much, as a quick trip to the internet will confirm everything. The universal transport was built on a Phillips CDV 400. Theta converted it using the best engineering and parts available. It has been described by innumerable experts as “the best sounding video disc player they could find;” “inherently superior to CD only transports”, “over engineered”, and “the best high-end CD transport at any price.” The one you are looking at is perfect --- 10 out of 10 cosmetics and operation (any blemishes you may see in the photos are just shadows). It comes with the original remote control, box, and packaging. Unbelievably, I could not find the manual, but if this is important to you, I can probably get you one either from Theta, the internet, or a friend who owns the same pieces (we actually bought them together --- another serious audiophile) and I’m sure he would loan me his for copying. The Pro Prime Digital Audio Processor is also the best at producing the kind of music I love. It has been called, “an engineering marvel…” with “deep and driving base, spectacular sound stage resolution, three-dimensionality, and dynamics galore.” One critic says it has a “huge transparent sound stage and stunning sense of space and depth.” (emphasis is in the original).Again, I would give you all the technical specs, but they don’t really matter and they are available online. Great sound does not change over the years. My Audio Research electronics, Linn Sondek turntable and Quad ESL 63 speakers remained the best when I sold them a year ago. Same is true for these two Theta pieces. In fact, I unconditionally guarantee them. If you hook them up and are not satisfied, send them back (at your expense) for a full refund. No questions asked. That is how sure I am you will love the sound.I am taking some risk by selling these together, but I really do not want to part them. I bought them together and have always listened to them together because of their synergy, and I think I should sell them that way.I always sell with no reserve, trusting that the public will appreciate what I have and bid it to an appropriate price. I am doing that here. So this is a no lose. You have an unconditional guarantee and can buy this wonderful equipment for the best offer. And, if you buy and pay for it when it closes, I will promptly ship. You should have it for Christmas; I hope and expect--but can't promise.. Shipping in the continental US only. Pay by PayPal. Good luck to all of you. Someone is going to enjoy wonderful digital sound.
