Preamps paired with DNA 225 or other McCormacks

I have a Final Music 5 battery powered preamp, and I would like to hear from Audiogoners and their experiences partnering different types of preamps to the DNA series amplifiers. I assume that the impedance matching would be similar with older McCormacks and the newer 125, 225 etc...series from Virginia.

and if you have, which preamps brought out the magic or brought out the strangest sounds?


I have a DNA 225 sitting and was thinking about changing my set up temporarily pairing with the stated preamp.

Thanks for the input.
