Yes, the 1.5s definitely have more bass. The Shearwaters have a bit more definition in the lower octaves, but the ProAcs are still accurate and very tuneful. While the Meadowlarks did a better job of disappearing, I preferred the ProAcs overall. The Shearwaters are quite often reputed to be easily driven...partially true. One can achieve very good sound on lower power, but they don't really come alive until you hit them with some juice...that carbon fiber woofer likes some power. The ProAcs are not perfect, but for tonality and musicality they win hands down IMHO. The 1.5's are much prettier, too...WAF.
