Perhaps I'm bias since I own the Pass XA60.5. Yet to really have that body of sound, that referred 3D feel, it takes very expensive speakers. Most people would say tube amplifiers made by McIntosh and BAT are outstanding. Yet to significantly outrun the XA60.5 with my Infinity Prelude MTS using the mentioned amplifier brands (their top model), it takes speakers costing in the range of $50K and up. Without mentioning name and thus can possibly belittle a well respected speaker model, even a $35K pair of speakers just does not quite make that leap. My current setup certain has that palpable feeling as if I'm almost at the live concert without the side noise. I'm referring to that complete 3D real life effect previously mentioned by several people here.
