The 8008ST will have a plate but no XLR jack. The 8008BB has both RCA and XLR input jacks; when the RCA jacks are used, a tiny jumper is inserted into two of the three ports in the XLR jack.
A Palladium II or Palladium 1K uses the same basic layout as the 8008; but is set up internally to be a true balanced design; and is a single-channel (monoblock) amp.
I'm using a pair of RCA-to-XLR adapter plugs on my Palladium IIs; using XLR-to-RCA adapters on your system is probably the simplest, cheapest, easiest solution if your Krell processor doesn't have RCA outputs.
First Guess: if you have reasonable-length interconnect cables, you won't hear any improvement from the balanced connection.
Another option is to sell the 'ST and buy a BB version; you gain the factory-installed XLR connectors along with additional power supply, larger storage capacitors, and 50% more output transistors.
