I have read a lot about them and most info says the are comparible with much higher priced speakers soundwise. http://www.hififorum.nu/artiklar/DynavoiceDFDM5/2.html the tnt audio review was the second to complain about the intensity of the treamble. Many people states they need a lot of time to break in but sounds really good after that, "brake in" usally means getting used to the new sound. Dynavoice definition us meant to play clean and somehow neatral for the price, i wasn't able to listend to speakers si it was a bit of gamble, i think it turned out good.

As for hdmi:
There is currently 3 standards used, hdmi, dvi, displayport. Displayport seams to be much better than hdmi but unfortionatly it's mostly used in computer monitors, a single displayport cable may replace 2 dvi cables and one usb cable!
