New or Old DAC

I am still awaiting an answer! How is A.C. Current that has been Rectified to D.C. Current, and is Voltage Regulated, and now supplies Analog as well as Digital Stages, Analog Based? Direct Current is Direct Current regardless if it is supplying Analog or Digital Stages, perhaps at a different Voltage, but it is still Direct Current! What is your basis of, "Analog Based" in Direct Current?

Seems pretty apparent, at least to me, that all John meant is that the circuitry (or at least most of the circuitry) in most power supplies is analog circuitry utilizing analog components.

Old DAC's are simply not as good as newer ones, even across price ranges, it's that simple. The underlying technology has advanced so much, it's not even close. The signal processing is so much improved through the new chips sets and firmware, that even the best analog output stage couldn't make up the difference.

BTW, who care, just listen to vinyl!!

Almarg-The Power Supply to Analog circuitry, as well as Digital circuitry, comes from the same source. It is Direct Current from the Rectifying Stage. This Direct Current isn't Transmogrified if it is supplying an Analog circuit instead of a Digital circuit. How do you Transmogrify Direct current anyways? Jmcgrogan2 claims that no-one uses Tubes, fancy caps or resistors in the Power Supply to a Digital Stage as opposed to an Analog Stage. The point is completely bogus, since both Digital and Analog Stages both run off of the same power source, Direct Current from the Rectifying Stage! Hello, Tubes are used for Rectifying AC to DC to supply Analog and Digital Stages! My System does exactly that, and it is certainly not the only one that uses Tubes for the Rectifying Stage. Direct Current is not Analog based, regardless of whatever analog circuitry is being supplied by this direct current. If I must, I will supply a list of Manufacturers and their Model numbers that utilize Vacuum Tubes in their Rectifying Stages. I guarantee you that there will be more than just a handful. This spans Amplifiers, Pre-Amps, CD Players, Digital Processors, you name it! The issue was never Analog Circuitry, it was fancy Resistors, capacitors, and Vacuum Tubes! All of these are used in a Rectifying Stage to supply Direct Current to both Analog and Digital circuitry-FROM THE SAME SOURCE!

Thanks Ben and Al. FWIW, you are right on the money Al, that is what I meant, but it's like pissing into the wind with some folks.

It seems to me that the only excercise that Pettyofficer is getting is jumping to conclusions. ;D
Hopefully he'll switch to decaf.

Pettyofficer, I can't even read or understand what you're writing, try inserting some breaks into your tirades.

You can do this by hitting the 'Enter' key twice.....try it. Your rambling may be less tedious and could even make you look more human. I will credit you for not mis-using the CAPS LOCK key.....those posts are also very difficult to read.

Cheers,
John

PettyOfficer -- I agree with at least most of your previous post, but I think that a misunderstanding may have arisen in this thread due to the term "power supply" being used by different posters to mean different things.

No one is saying that the dc current itself is "analog based." What is analog based is the circuit that generates it. The rectifying stage circuit IS the power supply, and it is an analog circuit.

The term "power supply," as used by most electrical engineers (of which I am one), and as I believe John was using the term, refers to a circuit, consisting of the rectifier, resistors, capacitors, etc., that you alluded to.

I can see how the words "power supply," in normal English usage, could be interpreted as referring to the current which is generated by that circuit, but it seems pretty clear that is not what was meant in this case.
