Bought 2 paradigm 90p`s on E-bay and also bought 2 Energy Audyssey A5+2`s from a local auction. Havent heard either set but I am sure they will outperform my $300 pioneer HTIB . Read the reviews first about the speakers but after I purchased them saw a forum advising another owner of P90`s to forget about buying an onkyo or denon receiver because of certain issues , mostly power and to buy a preamp and amp . I assume the audiophiles know what they are talking about , but am asking here for advice . I didnt even know what a pre-amp was until last week and at the same time was informed that all amps arent able to power all 5 speakers . Hey, I`m new . LOL . Help please.
