Having upgraded from B&W P7 cans to Sennheiser HD700, I’m yet to be impressed by the 272 headphone capabilities, hence my curiosity.
How good do you reckon the 272 headphone amp is? If I would to buy a dedicated headphone amp, what sort of price level should I target to get a discernible uplift in SQ?
I can’t comment on the N272 specifically, but I moved to a Heed Canalot from the SN2 headphone stage and run it with the Obselik PX power stage (which is the high end one, though the Q PSU is pretty good to), NZ$3K more or less. It’s on another level all together than the SN2 stage. I use the HD800 and run the Canalot of the NDX2 RCA analogue output.
I found the 272 headphone perfectly fine but did acknowledge that the unit is a jack of all trades. I added a Trilogy 931 which I found added a much improved tightness and oomph to the sound.
