I’m sure if your a good haggler at $2.5k rrp you can get them down, as many places sell Parasound in the US, in Australia no one pays rrp for anything but you have to haggle for it, isn’t it the same in the US?
And there’s always used, this one was mint and boxed.

And if you still have the hard to drive Martin Logan Accents, then this is the integrated for you.
As ML esl's can dip down to 1ohm, and the Parasound having good current delivery because it uses bi-polar (BJT) output devices and has decent power supply will not mind this load.
