George,Yes your right they do still make linear only in these two, pity they used smp power supplies with them.
625 S2 and 725 mono-amps...are they Linear Class-A/B amps?

" I suspect that the signal-to-noise measurement could have been tainted by very high frequency noise generated by the 625 S2’s switch-mode power supply"

All the rest of their range are Class-D though.
