Best affordable Linear Power Stage

@steakster thanks for the Aura recommendation, looks very interesting will check into it.

You're going to have a very hard time beating any of the Sengterbelle R-Core power supplies on Aliexpress at anything remotely close to the price and probably at 3-4X the money. I read somewhere online that there is a UK audio retailer simply marking them up and selling them for around 400 GBP. 

R-Core like the Allo Shanti so extremely quiet with digital gear and benefits from a good power cord and DC cable (which are also ridiculously cheap on Aliexpress). 

I own 3 of them, 2 5V and a 12V for my modem/router. That one may have been the least bang for the buck but the two 5 volts I have here on a Topping E30 MK II DAC and a Wiim Pro + as a streamer only have been a huge bang for the buck and both directly compared to a less expensive Talema torroid based 25W power supply. I was really surprised at how much it elevated the performance of the Wiim as streamer only.
