started in 1989 with this kind of ADI FS2 ancestor https://audio-database.com/MARANTZ/amp/pm-95-e.html, actually one of the first non pro DAC/Amp, 6 times more expensive at time with less functionalities and easily beaten by the ADI FS2 nowdaysStarted reading Head-fi in 2003 and registered an account in 2004, so it took me 20 years to get an "end game" DAC lol

Anyway, I could live with the ADI as my Thekk doesn't need more power (far from it).
But, unless you plan to go with difficult canet to drive and want a less "straight" presentation, I would recommend to give a try to the Trafomatic head 2

Power amp are pretty the same, but listening pleasure is not.
Appart for a matter of a very subjective choice (like mine), i don't really see the point to bypass the integrated amp.
