I thought the 52SE was better than the 52. It was more refined. Both were driven by a Rotel receiver with a Rotel CD player. It was the mid and highs that were most distiguishable.
There is no doubt about the technical superiority of the 52se over the 52, but the Dyn tends to be good with bass heavy materials which is more at home at a party than quiet late night listening. There is something about the Dyn that is cold and emotionally detached. If you like your music warm and inviting, there are so many other brands to choose from.
I agree with Jax - the highs irratated me after a while too, the bass response was excellent but bass gets boring after 5 minutes...(unless you wanna party 8 days a week) the (all important) voices didn't sound right too me, thin and 'missing ' for want of a better word... I think the sales and marketing are telling the designers what they want to hear... unsatisfying at low volume
I listened to the 52SE for a long time using Simaudio P-5/W-5 with AudioNote UK transport and DAC. I didn't find the speaker especially shrill ... a good test I find is the first track on the first Nora Jones CD ... I am not a big fan but I use this as one test track. On some systems, the bad recording comes out especially shrill and even painful. The 52SE didn't do too bad in that regard. Yet, I wasn't really moved by the speaker ... too lean for my musical tastes. Not that I am sure the Living Voice is perfect for me either, but switching to the Living Voice Avatar from the 52Se was night and day. Certainly I found the LV to be much more musical, emotional, and more room filling.
