Taking the humble chromecast audio to greatness

[raghupb]

Hi..good morning.

The ideal combination is a CVT > Isolation transformer > Linear power supply > CCA.

I assume this would be for the whole system, correct?
Cheers,

Any idea where I can source them from please?

Hi Raghu....

The above is the power chain for source components upto the preamp. Will be nice if one can use a star wired mains block with each power outlet isolated from each other. So that all source components are galvanically isolated from each other.

Better to have the power amps on a dedicated power line from the mains. Usually just an isolation transformer is sufficient for this. As fluctuations in voltage will not have much of a difference, as the large capacitors in the power amps will even these fluctuations out. But to be fool proof, better to add an CVT on this rail also, to make up for changes in fluctuations.

Hi rose...

I got the CVT from Amazon India site.

I bought the LPSU for the CCA from our forum member manniraj. And it is from a brand called Jay's audio. You can find it on ebay as well.

Iam still looking for an isolation transformer as I type this post
