I have had the CAT Ultimate for about 9 months, I just love it...I had a few defect problems with the unit, but CAT fixed them within a week.. The sound, especially phone, forget about it, it's just beautiful. I use SonicFrontier Power3, CAT Ultimate, Linn LP12 (Linn arm, BenzMicro Ref), B&W 802N, Electrocompaniet EMC1 CD.
