PD-Creative

+1 @ericsch 

I should have clarified that the MHDT Orchid is an external DAC. My experience with the internal DAC vs the Orchid (unmodified Node2i) is that with Spotify or Tunein the difference is slight. Just a little less glare. With the Creative board installed I found the sound night and day better with the external Orchid. I don’t know if the internal DAC is as improved but I suspect not and that the upgrade is allowing the Orchid to shine.

thanks for clarifying....

I've had Pawel's board on my Node 2i and it's a major improvement especially when paired with a good linear power supply. For the price and ease of installation it's a no brainer for Bluesound owners.

I've had my Node 2i for about a year. Shortly after purchase I added a Cullen C7 power cable. With the PD upgrade, I wouldn't be able to use the Cullen.  I don't think I would be gaining much with the PS upgrade.
