Best affordable Linear Power Stage

Thanks. I'll be curious to hear your feedback. 

@ghdprentice 

I am sure the best available power supplies are available inside audiophile equipment. 

Like this one in its separate box that connects to the Aries Cerat Kassandra? 

No outboard power supply necessary here, no DDC necessary either. This end-game DAC weighs in at 80kg. 

Yeah, I know, not affordable, but it is nice to dream.

I am considering purchasing the Singxer SU-6, digital to digital converter (DDC).

It looks like it comes with a "courtesy" external power supply (brick).

I was searching for a quality, linear, external power supply, and got overwhelmed with products that all sound like they are the holy grail of clean power.  So that led me to check this forum, and I found this thread.

I have a revealing stereo, and want to get the most our of my soon-to-be-purchased DDC.  So I want a high-quality, linear power supply, and the comments in this thread were helpful, and also somewhat inconclusive.

The DDC accepts between 7.5v and 9v (I have not seen any power supplies that deliver 7.5v, but have seen lots of power supplies that deliver 9v).

@hdm recommended the brand / seller Sengterbelle, with an R-Core.  But I read a review where the customer wrote that his gets so hot, he is concerned about it starting a fire.

Is his experience unique -- possibly got a lemon?

Also, Sengterbelle has many 9v models, at varying prices.  They all list basically the same "this is the best" type bullet points.  So how can I make an informed decision?

I am hoping that someone in this forum can give me guidance.

And if anyone knows of reputable reviews on these linear power supplies, please let me know.

Thanks...

@seymour-krelborn    Welcome to Audiogon!

Here’s a link to previous LPS discussions.   This current one also has good information.   

I have several LPS’s.  The only one that got ’ very hot’ was a low wattage unit that was paired with my Netgear Nighthawk router.  A household router is a very taxed component - especially when gaming or streaming movies.  To the touch, it was so hot that it did become a safety concern.

I replaced it with another unit that had: (1) a heatsink and (2) more wattage (VA).   This replacement LPS to the router runs fairly warm - but not hot.   The LPS (100 watts) paired with my DDC is slightly warm - just above room temperature to the touch.  And it’s been powered on 24/7 non-stop for over 7 years.  I don’t think I’ve ever turned it off.  The reason is to keep the clock circuitry in the DDC constantly warmed-up.*

Good luck in your search!

*The manufacturers of both my DAC and streamer recommend that the chip be kept warm for better SQ.  So, I assumed the same for my DDC.    I have taller after-market footers under all of my LPS’s for better airflow to dissipate any heat.
