RC22, I haven't heard any of the Alta Audio speakers, but I too have read favorable comments about them. And of course they have the benefit of 30+ years of additional experience Mr. Levy has had since his Pentagram days.
About a year after my previous posts in this thread I moved on to a $15K pair of the highly regarded Daedalus Ulysses speakers. They are of course better than the Pentagram P10 in various ways, but I'll say that they certainly don't make me regret that I had used the P10 for all those years. And as I said earlier in the thread the P10 handily outperformed several other large speakers I briefly owned and then sold during those years, including B&W 801s and two different pairs of large vintage Tannoys.
Best of luck in your search. Regards,
