Best All time 5.1 Pre/Pro

I’m working on upgrading my Linn AV5103 Pre/Pro, and am considering several units available. First, let me say I don’t need HDTV Switching, that is already taken care of. Second, I only want 5.1 surround, no need for more advanced formats other than DTS. The speakers/amps are all Linn, 7xAV5105’s, all active to 4xAV5140’s and one AV5120 as a center channel, AV5150 sub. I love the amp/speakers, but would like to change out the pre/pro, for several reasons, the second delay locking on to digital signals is annoying. Love the sound, but it has no multichannel inputs.

I’ve got several units I’m considering, and would love more input as to recommended units…

Several things I’ve considered are;

1) Cal Audio SSP 2500
2) Theta Casablanca I/II with superior DAC’s
3) Meridian 8 series…though probably out of my price point..
4) Proceed PAV/PDSD…still love the classics..
5) EAD theater Master 8000
6) Chiro 800/5.1
7) Classe SSP-75

I don’t particularly like Lexicon…to digital for me, and don’t like the harshness of Bryston/ B&K (probably annoyed several folks putting these two together but…)

I’m curious what else you all would recommend…….5.1 channel inputs are a big plus….though this system is mostly used for HT.
