PSU for Arcam irDAC

[blackhorn]

I have an irDac that Ive been using for the past 2 years, however last week its PSU decided to give up, I opened up the PSU and one of the small resistors was burnt, I was as it is wanting to upgrade the PSU as it appeared to be a cheap one, and now I have a reason, the input is 12v 1.5A, and is a linear PSU, if someone could point me in the right direction as to which PSU can/should be used for this particular application.

Thanks in advance.

Are you sure , it is a linear PSU. If possible post a pic of PSU.

It says LPS, here'c a pic of the label on the PSU

I also have a very old Nokia adapter which says LPS but I think it does not stand for LINEAR POWER SUPPLY

I think it stands for LIMITED POWER SUPPLY

What it means , I am also not very sure

 

[blackhorn]

Oh okay, so any 12v 1.5A adapter should do? Or should I look for a low ripple/LPS for the DAC?

Surely a good LINEAR POWER SUPPLY will take performance at a different level

What is rest of your setup, if you think it's resolving enough then surely you can go for a good linear suppply

Sure. I just need some direction with that, I put up in Delhi, any brands that I can look into with regards to the PSU?

 

[rikhav]

Nothing would be available in India unless someone is selling it

You can look for LPSU's available on AliExpress or more high end ones from UK or USA

It is SMPS power supply. you can choose Sbooster, but price wise , it will be a overkill for IrDAC.

for cost effectiveness, still you can buy IFI-Ipower

which is still better than your stock power supply

Thanks for the input, much appreciated.

You can check on : www.swagmanlab.com for linear power supply for your specification. They are making in Hongkong.
Thanks.

If you can find a good RCORE transformer and get hold of Sachin/Omishra PSU it becomes a very good VFM LPSU

The ratings of 12V @1.5A should be doable using this PSU board if you are into DIY and just put a small cabinet and you have a superb LPSU at fraction of the cost.

if you are into DIY

i can solder just fine, if thats the basic skill thats required, the components i'll have to look for.

Hi blackhorn,

Which one did you finally buy? I am also in a similar situation. The psu of my dac has stopped functioning

I am looking into the ifi, if I can source it somehow, as of now I am using a power brick that I used to power my external seagate hdd with.

I too was checking the same. On amazon its available for around 8K and on Tanotis for around 5K.

Though it is claimed to be low noise power supply but dont compare it with linear power supply performance. According to tests IFI has AC leakage current. Only thing good with it that, it is better than stock power supply of the equipments.

Update: finally pulled the trigger on a ifi 12v from headphonezone, sound signature has definitely changed for the better.
