Cambridge 640P Power Supply Upgrade


So I bought a Pangea P100 for my DACMagic (made it better)and figured, hey, one "wall wart" down, lets see if my 640P can use some improvement. So I ordered another Pangea (the name sounds like a holistic skin treatment, which I think there actually is). After a couple of days of use the Pangea PS seems to kick the 640P up to another level altogether...I now can highly recommend this cheap tweek. Interestingly (to me anyway), the stock 640P "wart" PS ran kinda warm and the P100 doesn't. I think that means something, doesn't it?

Hey Wolf

I don't recall what your turntable and cart that you are using along with you 640P and the Pangea P100. Would you mind sharing?

The reason I ask is that I put the DacMagic's 1500 mA Power Supplly on my 640P and didn't hear a drastic improvement if any at all. With the larger PS on the 640P the records I was playing the sound was still warm and inviting but I didn't hear a drastic change. I'm thinking I may have to do more comparisons with the different power supplies or my TT isn't high-end enough to hear the improvements from the larger PS being on the 640P. The TT I'm using with the 640P is a Technics SL-10.

Did you ever use an aftermarket power cord on either Pangea P100 Power supply? Also good one about the holistic skin treatment. When I searched Pangea on other shopping sites I often find that as a result too.
Nothing special...a carefully set up Linn Basik/Akito/Sumiko Pearl (upgrade coming as soon as I decide what to replace it with...not in any hurry as it sounds fine). I don't use any esoteric power cables as I have never noticed them improving anything beyond what my trusty ACE515 does...and I've tried! I did put a PS Audio AC plug in the wall though. Note that I thought the 640P sounded great already, just cleaner with the P100. Maybe I'm merely hypnotized by the blue LEDs!
I considered the Pangea P100 power supply for my Cambridge 640P and am holding off. Looking at the wall wart that comes with the 640P, it is a 120vac to 12vac supply. Then, looking at the Pangea information, there are two outputs. A 12vdc out and a 12vac out. I assume you would use the 12vac out to power the 640P. I wonder if the 12vac output is merely a direct tap off of the secondary of the transformer in the Pangea. If that's the case, the only advantage is the 12vac is coming from a larger transformer vs the wall wart. All of the regulation and filtering in the Pangea would be for the 12vdc output which would be totally unused with the Cambridge phono stage. Bottom line, you would not be using most of what the Pangea has to offer. Now, if one is using the 12vdc out of the Pangea to power a different device like a DAC, that would be a different situation. Without a schematic of the Pangea unit I don't know for a fact that the above is true but that would be my guess. So I personally have put the Pangea for my 640P on hold. For 99 bucks, it's probably a great value when powering a 12vdc device like the Cambridge and MF DACs.
