Hi everyone,Since electrical engineering is way outside my realm of knowledge, I am wondering if someone may be able to tell me if the following linear PSU I found on eBay would be a good swap for the wall-wart PSU (12V 5A) that came with my Auraliti PK100 (which is pictured above):
eBay item number: 111944028903 (Hi End 100VA Linear Power Supply DC12V 5A Ultra Low Noise LPS for Audio)
If not, could you explain why not? Also, are there any other options out there that may be cheaper, just to experiment to see what kind of improvement a linear PSU makes in this setting?
Thanks so much,
Chris

It would be helpful if they would show scope images of the low noise performance.
Image: Zerozone 100VA linear power supplyThe PSU you pointed at would be suitable for the Auraliti PK100, but I would opt for a similar PSU from the same manufacturer. The two PSUs are essentially the same, but the higher-priced PSU you pointed at features a deluxe enclosure and a voltage display, while the PSU I suggest features dual external heat sinks and is 6A rated rather than 5A rated for a 12 volt application. The lower-priced PSU with slightly higher current overhead and more efficient heat dissipation seems more valuable for a 5A load, IMO.

Hi Duster,
Thanks so much! Lower price and better made is hard to beat :-)
Where do you see that it is 6A at 12V? I can't seem to find that anywhere in the ad?
Thanks again,
Chris
Here's the info included in the eBay listing:-snip-
"We have following several kinds voltage for choose (Output voltage/current)
1. 5V/6A
2. 9V/6A
3. 12V/6A
4. 15V/5.3A
5. 18V/4.4A
6. 19V/4.2A
7. 24V/3.3A
(Please select your desired voltage message to tell us)."

BTW, I expect delivery of a Zerozone 100VA linear PSU in the next few days.

Wow; apparently I'm not having one of my more brilliant days; I read each voltage with the number before the decimal as part of the value, i.e., 1.5V, 2.9V, etc. :-0
Thanks!
Please let me know how the one you ordered works out for you!
Chris
I see what you mean; it could be confusing...
Now take a look at my prior post; I edited the text so it reads better.
