From what I understand, the Auditorium 23 was voiced around the DL-103 and is an excellent match. The problem is they don't come up used very often and they're quite expensive new. 6Moons raved about them in this review.
For commoners like me, the Cinemag CMQEE-3440A is much more affordable, yet very nice sounding. If you're into DIY projects, you can build a Cinemag SUT for less than $200. Or you can buy an assembled unit from Bob's Devices for $395. 10 Audio reviewed Bob's SUT last year. Art Dudley also commented on Bob's SUT in Stereophile and liked it better than Lundahls. He also mentions Auditorium 23.
