@manogolf I too strongly considered the Holo Spring 3, which can be bought with a decent pre-amp too. Mainly because I didn't want a 2 box setup, as the Holo May.
The Spring is lower spec than the May that's why I went for the 005. I've always used chip DACs so no issues there. The 005 is NOS and NUS no issues there anyway because I use an Aurender.
The Spring probably is one of the best single box ladder DACs in this price category at present.
