Kettle, I have used ARC products for the last 15+ years, products include: Amps; D115, D125, Classic 60, V70, VT130, preamps; SP10, SP15, LS5, LS15, some of which I wish I had back (SP10). All of Audio Research products are great, HOWEVER, I just bought a Cary V12 power amp last July and as stated by Sean, the sound stage (both width and depth) and the air between artist amazing, almost like magic. The ARC amps do have better controle of bass and are a little brighter in the top end. The Cary excels in the midrange. Again like Sean says, a very warmer presentation, exactly to my liking. A female vocal truly does sound like she is in the room, don't know how that is acheived but again like magic. I havn't owned any of the other Cary products, but everything I have read seems to come to the same conclusion, good luck.......Bob
