I am putting together a mid to high end system and am looking at the Pioneer VSX A10Ai-S or the Yamaha DSP-Z9 and would appreciate comments on either of these units. Whilst the Z9 has the power it doesn't accept DD or DTS audio via iLink. The Pionner seems the more rounded solution but I can't decide . . . Planning on using a Miller & Kriesel S150, SS150 and MX150 sub setup. Any comments?
