is the CD still the metal cover?? Edit.. got confused. This is the latest greatest, but not the metal version of the 4562s, right.

I've just ordered a pair from them too. I've already order some adapter boards so I could solder them my self but getting someone else to do it is much simpler. :eyebrows: Does anyone want to buy 6 adapter boards? :doh:Quote:

I've read about using sealed lead acid (SLA) batteries to power other equipment. Is this something that can achieve better sonic results than using a mains PSU with the 7520?
I tried it with the 7510 and didn't notice any improvement. Mind you it wasn't an expensive battery-one from a childs electric scooter.
Personally I wouldnt spend a lot because the improvement is likely to be minimal.
I think I'd wait for Stans new PSU first.
For any other fellow novices out there, I can confirm that someone with the electronics engineering knowledge of a peanut can install an LM4562NA into the line-out socket in just a few minutes. Just have a working brain when you try to de-static-ify yourself (next time I use a cold water pipe, not the one feeding into the radiator).
(Not impressed with the bass yet but its only had a couple of hours run in, seems a bit unexcited and at times mono-tonal so far, while if anything the soundstage seems slightly more compact than before.
However, female vocals are an absolute revelation, wasn't at all impressed with that aspect of the dac before but now they're smoother and much more realistic, a noticeable improvement the instant you switch on.)
Another alternative option to experimenting with battery power may be the Eaton 9-series UPS as described by Osku below, from thread #10, “Beresford TC7520 upgrades” on Digital Impressions?
I’ve copied it across, below:

If that is the case, then I would suggest him to buy a Eaton 9-series UPS to be used in between. 9-series UPS devices from Eaton (previously Powerware) transform AC (220-250V) to DC (60V) and then build perfect AC of your choosing (208, 220, 230, 240V). That is the best quality power there is available that I know of, and does not even cost that much (ok, it takes about 100W of power when in use). Those are used mostly in hospitals and mission critical computer systems (main servers, cash registers at shopping malls etc.). And one can also disturb the neighbors by playing loud music during an electrical break with the help of those UPS-batteries.

I have never understood those that buy or build expensive power cords since with about same cost you can have a device that creates perfect power that can be measured to have a perfect sine wave form even at load.
(I do not use such, we have just a Powerware 5110 1000VA for our computers).
I’m not sure exactly what is required in a good power source, but the Eaton 9-series UPS appears to tick a lot of boxes. Certainly claims to clean up dirty and erratic power source.
I’d appreciate clarification on what one hopes to obtain from the ultimate power source/ power supply?
I've just managed to get a cost indication on some of these Eaton 9-series UPS unit here in Australia. 9-series starting at ~A$1500 and 5-series starting at ~A$1100.
I wonder if they make tea and cofee also!
