New or Old DAC


I currently have an older Theta front end. Data ll transport & Chroma HDCD. I like it, even though it is old and discontinued. I would like to update my DAC first , I am looking for a Theta Pro Gen va. I know the sound of the older Theta stuff and like it. But, are there any newer DAC's out there in that $1K (used) price range that can really give an equal or better performance than the Pro Gen Va? Do the newer anti jitter (re-clocking) DACS fall into that price range?

thanks, mike

Almarg-
I am going to try this one more time. It doesn't matter if one is refering to the DAC as the entire component or strictly the the "digital to analog converter" dac circuit or chip! There is no distinguishing the power supply within the overall component. Everything that is the Component, as well as what is part of the component, is fed Direct Current via the Rectifying Stage. The ONLY thing that gets fed anything else, Alternating Current, is the Rectifying Stage itself. The ONLY difference to the power supply of each part of the Component is the Voltage, and Capacitance of the DIRECT CURRENT via the Rectifying Stage! The DAC Circuit is supplied DC from the same source, the Analog Output Stage is supplied DC from the same source, that source being the Rectifying Stage. There is no distinction, other than Voltage and Capacitance, between the power to the Analog Output Buffer Stage and the D/A Converter Stage. Other than Voltage and Capacitance, Direct Current is Direct Current no matter what it supplies. Why do you and Jmcgrogan2 insist that there is a distinction between Two Direct Current Power Supplies that come from the same source? Do you not concider the Direct Current Output of the Rectifying Stage as being part of the Power Supply that we are refering to? Other than Voltage and Capacitance, what is the specification of the distinction between two Direct Current Power Supplies that you are refering to? Wave Amplitude and Cycles Per Second? Two Direct Current Power Supplies, one to the Analog Stage, one to the D/A Converter Stage, what is the distinction other than Voltage and Capacitance? Need I remind anyone that these two DC Power Supplies come from the same source?
This is basically the same logic and reason, as concidering the Lungs as not being part of the Human Circulatory System. If you eliminate the Lungs from the Equation, just what is the Circulatory System circulating?
Sorry to notice the gap in your logic and reason being as wide as the Grand Canyon. The best that I can do is offer you a shovel.

We don't (or at least I don't, and I don't think John does either). I suggest that you re-read my previous posts.

No, you needn't remind anyone. My point is that I don't think anyone has said anything to the contrary.

Pettyofficer: Sorry to disagree, my Space Tech Lab DA-64XT
DAC utilizes an STR-104 Tube Rectifier. This
Rectifier does have two very, very large Tubes
that supply power to all of the components
within the DAC.

Nice try Almarg, components within the DAC refers to the D/A Converter Chip Set amongst other Circuits, not the entire Component. Notice the use of the "Plural" version of component, meaning more than one. Notice the use of the word "within" meaning inside. Perhaps I am really going too fast for everyone, or is everyone trying to pull a fast one over me! You are going to have to try a little harder than that!
I was a pettyofficer in the US Navy years ago and after hours spent a great deal of time drinking heavily as well.

Glad to see the tradition continues.
Almarg-everything that you and Jmcgrogan2 have suggested-can only lead to one conclusion. That you and him both believe that there is a serious distinction between the DC Current Supply to the Analog Stage as opposed to the Digital Stage. If not-why then bring up the issue of Vacuum Tubes being used in one or the other, when Vacuum Tubes are being used to supply power to both? Just what the Hell is your point? Mine is very simple, when Vacuum Tubes are used in the Rectifying Stage of a DAC, they become part of the power supply to both the Analog and Digital Stages! Someone is obviously NOT just strictly using Tubes in the Analog Stage as opposed to the Digital. If the Rectifying Stage is Solid State, and Tubes are used elsewhere, then Jmcgrogan2's statement might make sense. Why is this so hard for everyone to understand?
