Hi all, I'm no audio reviewer, but just wanted to chime in on my experience. After getting hold of the Rockna WaveLight DAC, I was awed. My previous DAC was the Benchmark 3B, which I thought was already remarkable. The Wavelight DAC thrashed the Benchmark 3B that there was no need to do an A/B on it. After enjoying the WL DAC for 2 months, the Dealer in Singapore (where I live) tempted me with the WLS. I began to do lots of Googling on whether a streamer / server could make much of a difference. Did not want to spend so much just for a marginal difference. Alas, I took the plunge! Straight out of the box, I could immediately hear the sonic differences, much more spatiality and ultra-high resolution, but it sounded so ahem...digital!! Running it 24hrs for 2 days, I must say it took my music to a new level. The Rockna Wavelight DAV and WLS is now my end-game digital front. If you're wondering how much difference the WLS makes...stop wondering. You'd realize how much you are missing out!...Mike
