I use a set in my MSB DAC and they are a huge improvement to my old out dated DAC. https://www.bursonaudio.com/ https://www.bursonaudio.com/products/supreme-sound-opamp-v6/

While I’ve not yet tried them, in principle I love the idea. Plan to get some V6 units for my NAD PP2 which I’ve already upgraded the power supply on from a wimpy AC adaptor to a LM7824 regulated supply with 4700uF pre-reg filtering and a Schottky rectifier diodes.

I know of the Burson, they are expensive, but heard good things about them, space would not be an issue as its plenty of room, even put film caps in place of the 4.7uf bipolar caps? maybe THanks Imhififan, only one i can see in the LME49860, which isnt bad for a cheap opamp.
