I have had the p8ltd for the past 2 years till I replaced it with the c8ltd (a big improvement by the way). I have used a nuvista m3 integrated with 250 watts per side and with tube pre and ss output. The tubes have 100,000 hours so there is no fuss. The combination is terrific with as much authority as I could ever want. A friend had the vt100 (not sure if it was mk 2) and p8ltd and after hearing my p8's and nuvista bought the nuvista. You could pick up the nuvista used for a very good price,there are several on audiogon. Another friend has the rowland and likes it a lot with his piegas (though he recently downsized the piegas due to change in living space size). A third chap has the moon w5 (the bigger ones) and this too sounds very good but I'm not sure worth the difference. If you talk to the people at sanibel, the importers, they would suggest aloia, perhaps biamped with a 13.01 and 15.01. Calloway, who posts here, has had a number of amps and has tried everything from tenor on down. He settled with goldmund, but it is very expensive. By the way, I didn't ask the rest of the system, your room or listening tastes but these will all infulence your choice. My system is up on line for what its worth. One final thought is to go with the nuvista or keep your old gear and consider an upgrade to the c8ltd. Thats what I did and the effect is stunning. Hope this is a help. If you have any questions drop a note.
