IMHO: the Cary Slp-05 is second to none!!!! Audio Research has the name....... Cary has the sound!!!! Audio Research, & Cary both have their own 'House Sound'. Everything, of course is system dependent. If you're system already is too warm, then the Audio Research. However if you're system is etched, or on the analytical side, then Cary. However, I find myself to be able to listen to the Cary 'flavor' for longer stretches than the sometimes 'whitish, analytical' AR, house sound! The final arbiter is what sound You like, and are trying, and can live with!!!....J.C. A better comparison is with the Ref.III
