Nuck: I already have joined David's thread, but I thought it might be more biased towards the Evo so I started this one. Currently I have Simaudios Titan 5 x 200 powering my mains, center and surrounds using an Anthem AVM50/ARC pre/pro. I was looking to get the W5 to match with the Titan to run my fronts and moving the Titan to the center/surrounds and rears. Because I could not find a W5, I bought the Evo on a whim and will be trying it on my mains. Hopefully it will pair well with the Sim even though it has less power.
Got the eVo4 and using it in bridged mode (360W x 2). Having some hum issues currently, but getting those taken care of. Ignoring the hum, this amp is unbelievable. The music has so much air, it seems holographic. Midrange detail, soundstage and imaging is the best I've heard. I'm sure I would have been very pleased with the W5 as well, but I can't imagine anything being better than this. I know as good as my Simaudio Titan is, the eVo is better on every level.
