@ilikeclassical You should also consider the following. I do not like headphones, but these are. different (especially the (SR1a/SR1b). They do not replace 2-channel for me in my office, but they do serve the purpose of late-night listening. I used to look for gear that sounded great at low volume, which I have, but I now always use the phones late at night.
I have spoken with people who have replaced entire 2-channel systems, such as Magico based to go with the older SR1a. The new stuff is supposed to be even better.
Send me a DM if you are curious about what the heck I am talking about.
