I replaced OPA2134 / OPA2064s on a Music Hall DAC with Burson Audio discretes. Definitely an elevated experience.

Would certainly consider Sparkos today.

Those won't fit in the Fosi...

  but there are adapter extensions which allow the Burson modules to lie down.

    It is a bit of a shame to add extra adapters and longer wires in the signal path like that, but they do work.
    
    Burson's latest is now up to V7, and Sparkos best opamp is reported the Pro version SS2590, but that comes with "Pro 6 pin" configuration and in singles, so various adapter strategies would be required.

I had NOS BB's in my stash and there was immediate improvement, and I mean mucho. Depth was the biggest diff, in your face different with vinyl and depth. Not gob smacking but much better and more pleasing.

The 5534's are much older and cheaper, and not up to snuff. They included them in the original build because it was, after all, a ninety dollar amp and not a SOTA design.

If others are so inclined then so be it. This little tiny amp drives my Quads to satisfactory levels, fairly loud and with ease
