New/upgraded TC-7520 power supply?

[chebby]

Hello Stanley.

On the Beresford.me website TC-7520 page I am seeing a new power supply (with "exclusive to beresford" printed on it).....



http://www.beresford.me/UK/Stereo_Au...2FTOSLINK.html

My TC-7520 (purchased early Feb) has the older style plug-top PSU.

Is this new style PSU a 'repackage' of the same one I have or an upgraded version?

If it is an upgrade, is there any way I can purchase it please? (Your website does not list it as a seperate item.)

Thanks

ps what is the other - circular - object pictured on that page with the 'exclusive for beresford' label embossed on it?....

I too would be interested to hear about the new PSU.

He mentioned previously that the circular cap is the custom made power cap inside the 7520. It took awhile to get the embossed top made, but all 7520's have that cap, even if not marked.

I'm pretty sure.

New PSU? Want to know more!

Stan has previously indicated that a new upgraded PSU was due out about end of March. Being a new product, it has apparently been subject to the relevant approval processing procedures. I suspect this action is taking longer than anticipated. I’m sure Stan will enlighten us all once it is available.
(The picture on the website might suggest that it is not that far off.)

Since my last update I have upgraded to the 'new' TC-7520 power supply. It arrived this morning.

I have connected it with a TM3 Connections shielded/braided figure-of-eight mains connector (with high quality MK Tough-Plug) that I had lying around....



Not quite sure if it has improved anything yet. Too early to say after an hour or two. But it certainly does not sound any worse and at least I have what is now the 'standard' TC-7520 PSU rather than one borrowed from the TC-7510.

Chebby pease keep us posted about this. When Stan first talked about an upgraded supply he was trialing linear supplies then he changed to a switched mode ps. If the improvement is minimal I may look for a linear one.

Why would a linear external PSU give a larger improvement compared to the TC-7520 external PSU? The TC-7520 draws its supply from the internal PSU, not the external one. The external PSU is used to charge up the internal PSU and keep it topped up.

'I'll have a new external power supply out by March. After wasting my time believing all the junk that various power supply designers from numerous factories have been telling me, I realized that these guys weren't even suitable to clean my shoes. So I have worked on a matching design whose sole purpose is to feed my DAC and a few other products I have in the design stage. The DAC doesn't need a lot of current. In fact it only draws 100mA on average. What it needs is a low ripple voltage and current. So far only off the shelf linear power supplies can produce those types of figures at a low price.

That doesn't answer my question I posed to you.
