Narrative:

We were on a return flight from sgu airport to whp airport via the barstow VOR following victor 394. Las vegas approach cleared me into class B airspace and approved me to proceed barstow direct after climbing to 10500 ft. As we were cruising barstow direct; approach called out airbus traffic at about 2 O'clock position and 5 mi at 10000 ft. This was right into the setting sun for us and neither of us could see anything directly into the sun. I communicated that I couldn't see the traffic. Moments later; approach called out the airbus traffic 2 O'clock position and 1 mi at 10000 ft. I communicated a second time the traffic was in the sun and I couldn't pick it out. I remember looking at my altimeter and my GPS to confirm my altitude at 10500 ft. At that moment; my passenger found a visual on the airbus and pulled up on the yoke. I looked at the altimeter then to observe 10700 ft and 10750 ft on my GPS as the airbus flew by right underneath us on a collision course. I don't think I've ever seen an airbus that close. I was so shocked. I was silent. I could hear the sound of my heat pounding over the engine. The airbus looked higher than 10000 ft. If we were on that close of a collision course; why didn't las vegas approach vector me a turn till the airbus passed? In any case; we're alive; but my opinion of las vegas approach is compromised.
