Yes, Dan does good work; and I agree with @samzx12 . Mods are not good investments if one is looking for a decent return on resale. I found that out when I went to resell my first TRL-modded CD player. Folks will not pay much above the stock resell price (40% - 70% of new ... depending on age). This is especially true when the used modded player is priced much above the "new" price of the latest iteration for the same brand.
But if the goal is to extract the absolute best sound from a piece of gear, then that's another matter altogether. Besides Modwright, I have a couple of other pieces modified by Joseph Chow (Audio Horizon). Is the next person going to be willing to pay me for what those guys did? Probably not. But I have thoroughly enjoyed the sound and how the mods improved my listening experience. So it's been worth it.
