I beleive Ayre's "MP" filter they use in the "listen" switch position is exactly this sort of filter arrangement on their C-5xeMP disc player.
"I spent a lot of time reaching these conclusions. In the end, I concluded that the 44 kHz formats were inadequate and that it was probably not worth obsessing over this unfortunate fact of history. Filter choices at higher sampling rates are much less signficiant."
I agree that it probably isn't worth losing sleep over, too. I own a Rega DAC (was my main DAC but now in back room) - and it allows you to choose filters at the press of a button. Fun stuff to tweak away with 48kHz and below material - and would generate some minor differences. At higher resolution, didn't seem to have very much in the way of impact at all.
The Berkeely Audio DAC-2 has a defaul setting. But it also has several other filter settings, that are really meant for stdio use - since they "simulate" crummy filters that might be in use in some playback devices. I have cycled through them a couple of times and agree with their assessment. (I think their regular DAC's are "one foot in the studio")
