Bluesound Node (2021) PS upgrade to Teddy Pardo; is it worth it?

What digital coax cable are you using?

Thanks again. 

I don't use the Node DAC at all, love the Denafrips. I run them with the the Naim Nait 5si, and Quad S2 speakers.

I love my system in essence, I just feel the Node is the weak element. A/B testing from the Node DAC and Denafrips, the Denafrips is hands down better, and I feel the Node is holding it back. I feel it has more to give; the Teddy Pardo may just give the Node that extra push from what you have described.

Thanks for your help, much appreciated 

It depends on your system (amp/speakers), but if your system has enough resolution, it will definitely show a difference when you upgrade a streamer/transport with a linear power supply - even if you just use it to send digital coax signals.

As far as Bluesound Node DAC vs Denafrips, it really comes down to personal preference on sonic signature. Based on what I have read, the Denafrips sound will have more weight and be thicker (maybe more natural as well due to the resistor ladder dac circuit).

If you want to try using the Blusound as a DAC, I would not do the Teddy Pardo solution. In addition to the types of caps and regulator Teddy Pardo has, the Buesound internal adapter card Teddy supplies does not have any additional filtering. It just has 3 regulators on the board to split the incoming voltage.

If you want to try to use the Blusound as a DAC and want to upgrade to linear power supply, I would get this internal adapter board (installs inside Blusound Node and replaces the internal power supply board):

Then you can use any external 5V linear power supply. I would recommend Farad Super 3. This solution is much more expensive than Teddy Pardo, but I think the results will be much better in the end if you want to use Blusound as a DAC.

@auxinput thanks for that, that's really useful. I thought there would definitely be a SQ improvement, but not at the level you've described. Do you think I would see much improvement using only the coax digital out on the Node, as opposed to using the DAC in the Node?

Thanks very much 

I installed the PD Creative PS board in my 2i and added an inexpensive LPS that I found on Amazon in conjunction with my modded Orchid DAC. Heard a difference for the better right away. More relaxing sound, bigger sound stage cleaner presentation and the 2i is just streaming. I may try a more robust LPS down the road but I'm in no hurry to.

My recollection is Pardo first made a name for himself with excellent LPS for NAIM analog products....

I do have two of his excellent PS running NAIM digital gear... servers...

I don't want to discourage you with my comment.  The Teddy Pardo is a great product and if do the Teddo Pardo upgrade to your Bluesound, it will definitely be a significant upgrade in sound quality. 

At £400, it will be money well spent.  You would have to spend upwards of £3,000 to get a better dedicated streamer with good linear power supply and clocks (such as Aurender or Auralic).

My opinions are all based on listening.  I can't really give you a good "engineering description" of why I'm not getting the best sound from Teddo Pardo on analog components.  Sorry.

Anybody know what the cost is of the upgrade kit from the manufacturer in Poland? I think they offer LPS.

@auxinput 

Please explain the issue with the Pardo regulator circuit. He specifically  mentions it on his website.

I have recent experience with Teddy Pardo power supplies.  If you are going to use Blusound for a transport only with Denfrips as a DAC, then the Teddy Pardo is just fine.  However, I don't think Teddy Pardo is that great for analog device (such as DAC or preamp).  This is due to the types of main power supply caps it uses (Cornell SLPX) and the regulator circuit itself. 

For a digital transport power supply, it is very good and will defintely be an improvement over the stock Bluesound switching power supply.
