Spare Bryston B60 for headphones, or 2nd system?

Hi guys/gals, after recently upgrading my main system I’ve conveniently ended up with a spare Marantz cdp, some Straightwire cables, speaker stands, and a Bryston B60. My original intentions were to sell the amp and do something completely different with the cash, but I realized I’ve grown sentimentally attached to it, been through 19 long and crazy years of my life, so I’m keeping it until the grave. How many pieces of gear, or anything really can you say that about? 

Anyway, as the title suggests, I’m in a bit of a fun dilema, wether to buy some headphones, or a set of bookshelves. I imagine some of you will just say, decide what the heck you want, but I’m curious if the B60 could decently and enjoyably power some headphones, or if would be, advantageous let’s say, to just pair it with speakers. It’s a bit difficult to find information on this topic as there are mostly articles from the early 90s, and just not really applicable to the present. I would be totally happy setting this up as a bedroom system with speakers, or set it beside my leather reading chair with some cans. This is just a fun, budget second system, so I probably wouldn’t spend more than a few hundred dollars on the cans or speakers. And most likely used to get more bang for the buck. 

Any suggestions or insight?
