To the OP, you never mentioned your budget!
1. For around $1,000 perhaps you should consider the Pre/Pro Onkyo PR-SC886P, but it also has an excellent video processor on top of a great preamp section, with Audyssey MultEQ XT and Audyssey Pro capability. Oh, and excellent Dacs too, with the Texas Instruments Burr-Brown PCM-1796a Dacs. Plus a whole lot more gooddies for your audio listening pleasure. It is the very best value on a top notch Pre/Pro. It is so fully loaded with the very best, that it is very scary and unbelievable at that price.
2. Also, the Yamaha RX-Z11 A/V Receiver can be had now for only $2,000 which includes a top notch audio preamp section with a powerful amp section as well, with a total of eleven amplifiers.

The Dacs are Texas Instruments Burr-Brown DSD-1796 for all channels.
The THD+N %, the S/N ratio (A-Weighted noise), the Crosstalk (Channel separation), the Frequency Response, Damping Factor, Output Impedance, Sensitivity, Input Impedance, Output Power, Dynamic Output Power, Dynamic Headroom, etc., are all top notch figures.
It is built like a real tank at weighting 75 lbs.

It is THX Ultra2 Plus certified, and you can adjust all parameters for all its DSP audio modes till the end of times.
It's the top Yamaha, the one above all.

Its audio quality in two-channel stereo listening only is unparallele, in a class of its own from all Audio/Video Receivers, perhaps only surpassed by the Arcam FMJ AVR600 A/V Receiver; but that last one will cost you much more.
Anyway, some food for thought.
Have fun deciding...
