Linear power supply

Before spending money on that, you might want to read this Benchmark Media white paper on SMPS, if you haven’t already.

I've used Benchmark components with SMPS and have owned a Classé preamp with SMPS for about 10 years. They all have been exceptionally quiet and well-performing gear. 

Is the idea that an SMPS causes problems an audiophile myth? Every audiophile, I guess, has to weigh the evidence and decide for themselves.

Yes, more big players like PS Audio are shifting toward SMPS as well, because of higher efficiency, lower noise, compact size, and faster transient response to dynamic power demands. But the question is whether the one used by ICON is up to that level - which I doubt is the case.

Not sure if others have launched the same effort but here is one:

I think well designed SMPS is great, but not every device out there ships with one.  For my exclusively digital devices near my audio I use iFi SMPS adapters. 

I'm not sure if the Benchmark article covers it, but SMPS have two issues, potentially when not well implemented.  1.  The noise on the DC end, 2. The noise they put back into the AC. 

It's also the 21st century so I hope we rely much more on them now!

Pretty sure, adding a LPSU to an Icon before the warranty has expired, voids warranty. The Icon has not been on the market for even a year yet. We have to wait till December. I have a pretty hard time believing that the $100 LPSU would sound the same as an S booster or Teddy Pardo offering. Depending on where you want to go with this set up. One should ask, why am I modifying a midtier audio product when I could be putting that money towards a higher tiered offering. 

Mid-tier?  Wait until you tune into 7:45 of this review by TAS!  Essentially, the host is saying the $35k combo of a $28k DAC and highly raved Aurender N200 here sounds better than ICON but the difference is subtle.

Also, other companies may have been working on developing it, but so far, Teddy Pardo seems to be the first and only vendor offering an LPS mod for the ICON.

If you want the best in class then Linear Tube Audio

if ordered on Audiogon $700 and the build quality  alone class leader up to $1200

and comes with a great DC cable most charge $150 for.

I added the Teddy Power to my Eversolo DMP-A6 Master. I honestly wasn’t sure what to expect, but it far exceeded anything I could have hoped for. On top of a cleaner, more full bodied sound, it added a level of depth and space as well. Worth every cent! Even though I already had

I actually have the Icon in my second system and didn’t know TP had the PS for Icon (thanks @lanx0003). Going to look into that now!

Finishing first paragraph above- even though I already had the Eversolo going to a DENAFRIPS Hermes to a PONTUS II 12th DAC. The TP power supply still took performance to another level…

Teddy pardo!

Wow there are some good reviews on the node.what a great age we live in.i do like power supplies lots of it even when the whole neighborhood lights dim when I turn all the amps up.we could get into cd as streaming vs lp but that's another day. Enjoy the hunt.😃

I understand your node responds well to an LPS. I added an Sbooster with the Ultra upgrade to my Qutest, with nice results. chatGPT is very high on the iFi SMPS & its very low noise. I have ordered one for my TT & one for my miniDSP.

For my Bluesound Node 2i, I went with a dual output multi voltage selectable  Keces LPS. through Power Holdings. Good guy to work with. Caught mine on a good sale too.

Use 2nd output for my external DAC. A noticeable upgrade to the Bluesound.

I think I got the conversion board from that place in Poland. TPs boards would not work in mine, but they made very fair refund.

Sbooster.
