I do not have the p10's nor heard them but I do have the p8 ltd and am delighted with them. My choice was based largely on the size of speaker,ie why I excluded the p10s. The big difference in talking to the dealer is the slightly deeper base and the rear firing tweeter (a second one) which is not important in a bright room. The limited group are more 'careuflly' constructed although with piega I find that tough to believe (perhaps I should say they are better reinforced and use better crossovers) and they are very carefully matched. The finish is really amazing, the best I have seen on a loudspeaker. A number of friends on the net have the p10 and have listened to both and say they are very close indeed. If size is an issue the p8ltd are small in appearance and huge in sound and visually very appealing. If price were an issue the p10 start cheaper but can get slightly more expensive with all the extra trim. If you have any questions on the p8ltd drop me a note, 2 other friends have bought them after listening to mine.
