Just received my LHY Linear Power Supply

I just received an LHY Power Supply from Vinshine Audio.  As always, Alvin and his team were wonderful to work with.  The addition of the LHY to my Innous Pulse Mini does make an audible difference.  The attack of bass has increased, as well as enhanced detail.  I wouldn't say it's a night and day difference, but one that is incremental.  I think anyone with a streamer that uses a switching power supply would experience a nice uptick in performance with the addition of a linear power supply.

Greg: My first foray into LPS was with a relatively inexpensive 15W Weiliang (also sold as Breeze Audio I believe). These can be purchased with either a Bingzhi transformer or an upgraded Talema transformer. I have the latter as by most accounts it is supposed to be significantly better than the Bingzhi.

Decent improvement but for marginally more money you can buy a much better power supply on Aliexpress. I'm partial to the R-cores for digital gear after doing a bit of research on them. 

 

The Sengterbelle R-core LPS's on aliexpress are excellent (I have 2 of them, both 50W 5V 3A versions) and I also have an 80W 12V 5A linked below that I am currently using on my DAC that is very good.

I've always used good quality power cords to the LPS as well-my current preference is Preffair D503 based cords-also very reasonably priced-and I've purchased upgraded DC cables for all the LPS's from KAM audio in Hong Kong (about $30 for a good DC cable).

Thank you very much @hdm, I am thinking of replacing the wallwart PSUs from my digital chain (router, switches, etc). I do buy a fair amount on Aliexpress, I will look at the options you mentioned. Thanks again!

This would be a very good choice. I have a version of this with a digital voltage readout on the front (very slightly more expensive) which is very good but have actually read that the voltage readout light introduces some noise and can be snipped-which I haven’t done but might do if I get around to it ;)

Edit: I actually have a single output version of this. Link is to dual output.
