What track really made you sit up?

after reading the forum for a while last night I downloaded a copy of Audirvana to my iMac and synced my iTunes library. The rest of my fairly modest, and I'm sure some will say unbalanced system comprises an Arcam IRdac, nac282' napsc, hi-cap, nap150 and a pair of motive 2's. Initial results were that this was a good improvKent over iTunes, especially playing some of Linns gifted festive hi-res tunes, then this morning a track by Richard Hawley came on called you lay me down, wow, it sounded amazing and really made me sit up and listen, showing what a well produced and recorded track can really sound like. So I guess an average system can sound brilliant with a well made track, can an amazing system sound great with a poorly produced track? But then there's the well made track on the brilliant system... I'll keep chasing the dream....
