anyone using Mac & Apogee Slants?

Is anyone using or have used Macintosh with thier Apogee Slants? I'm particularlly interested in help of how they sound (neturality or do they have a signiture) and what's thier presentation like as I'm looking at the integrated (MA6300,MA6500) to pair with Slant 6s, yea or nay as to this combo listening to soft rock, new age, blues. Thanks
