Yes, they are great, the ribbon tweeters allow you to hear all the delicate sounds, e.g breaking glass and dripping water after an explosion - the detail is all there and by golly they look good too!!!!
I auditioned just about everything I could lay my hands on and was just blown over when I got to the Piegas. I settled on the P4XLs, P4L, P4C and P SUB 1 - I have not regretted it for one moment and the wife is pleased as well because they look superb. It was a little more than I wanted to spend - but woth every penny. As I intended to do this only once - I had to get it right!!!!
I use a Yamaha DSPA1 which I upgraded by using an EZO K5.5, a 5 Channel External Amplifier. I had read a review about the K5.5 which was exceptional some time earlier, but had never seen or heard one, however when I went to audition the Piega system the demonstrator used one in the demo. Fantasic!!! Also it was finished in Silver which again looked stunning as well as the best sound I had heard.
I do not know where you are, but if you get the chance you should visit Audio Illusion which is based near Slough - the guy there sure knows his stuff!!!!!
