Krell DVD Standard

Right now I am using a Marantz DV-8400 for DVDs, Arcam FMJ-33 for Redbook. I'm not interested in SACD. I am using B&K Ref 20/AV5000II and Krell 400xi (theater throughput). I would like to combine the two players into one. I was wondering how the DVD Standard stacked up? Others considered were Esoteric DV-50 and Linn Unidisk 2.1.

FWIW I have an Esoteric DV-50, and had a Linn Unidisc 2.1 for several weeks. The DV-50 is far more accurate, has much better bass, and give the instruments better seperation...on the flip side the Linn has a smoother, kind of 'happier' sound, but was definitely lacking in the bass. I kept the DV-50 as my wife and I both found it to be the better of the two.

I unfortunately can't comment on the Krell, haven't heard it.
