When we reviewed Antec's Sonata IV recently, we found it left a lot to be desired. Antec had updated their Sonata design, but barely, and the enclosure as a whole felt grossly behind the times. Apparently some of Antec's engineers agreed, because we have the brand new Solo II in house now and there's clearly been some serious retooling. But is the Solo II enough of a step forward, or does it still have some growing up to do?
