Which External Linear PSU Upgrade for my Router?

+1 For Ferrum Hypsos 

The Ferrum Hypsos is $2k down here at the arse end of the planet. Is the improvement worth that? 

@campo007 Don’t buy low quality things that may set your house on fire.

The router doesn’t need that great of a linear PSU. Something like this Topping unit should be ok.

If you need to do a streamer or DAC with a linear PSU, don’t get any lower than this KECES unit for $550. It has 2 outputs and you can vary the output voltage for your use case, i.e. has more utility. Or you can try the KECES P8 for $900.

Putting a $2000 LPS on a $200 router really doesn‘t make sense. That said upgrading with a $100 Aliexpress lPS made an audible difference. 

I bought a linear PSU from AliExpress costing me AUD $400. Let's just the difference wasn't subtle. Very positive and far exceeded what i paid for it. 

Then i upgraded the DC cable to the Ediscreation. Again, a very positive change.
