Help with new system

I'm starting a new 2ch system that I will be running out of an iMac. I was wondering if I could gather some opinions on what to use (can't audition everything, want to narrow it down to a few finalists first). Obviously I'd like every part of the freq. range to sound good, but I am looking for a sound with smooth treble (but not veiled) that is not over super detailed/sharp, punchy bass, and in general a cleaner sound instead of something warmer and more colored.

Speakers: I have decided on Ascend Sierra-1's

Integrated Amp Shortlist:
Creek Evolution 2
Bada DC-222
Audiolab 8200a
Cambridge Audio Azur 651a
Musical Fidelity M3i

DAC Shortlist:
Schiit Bifrost
Cambridge Audio DACMagic+
Audiolab M-DAC
Musical Fidelity V-DAC

Out of the amps, I have seen that both M3i and 8200a require careful system matching or they could sound overly forward/sharp. Out of the listed components, what would they best be matched with. I like the tube customization of the Bada, but am not sure if the tubes would fit my sound tastes.

For the DAC's, the M-DAC is the most expensive, but also seems to be the most well liked. I have read that it also can have a more forward sound.

Any opinions on the listed items would be great. Any additional recommendations would also be welcome.
Thanks
