    PARASOUND 2250 VS EMOTIVA XPA-2

    its the factor that is the issue... sure you can say, well... 27% of zero is still zero. But really 27%(.27) is about 40 times the THD of the 8ohm load(.007*40).

    now if you run a single set of two speakers @ 8ohms, I guess you are good to go(as I would be also), but if you run more than 2 8ohm speakers you are at 4ohm minimal load consistently.

    I need to look elsewhere.

    I am thinking about staying with class D Ice based Amps because the floor is so effing outstanding... black on black on blackness. Either that or I need to spring for the big boys... the X1's

    even Paul was into SS so... [:P]

    I need a new amp, and I have been reading a lot about emotiva... I wanted to go with two U1's monoblocks for 2 channel. then I started reading about what happens to the amps at 4ohm loads.

    UPA1

    THD+N ratio @ 8ohm = 0.007337 %

    THD+N ratio @ 4ohm = 0.279648 %

    that is a huge factor increase.

    as a matter of fact, the more I looked, the more the whole emotiva line had this giant factor increase at 4ohm loads... EXCEPT the X1's(XPA).

    XPA1

    THD+N ratio @ 8ohm = 0.003260 %

    THD+N ratio @ 4ohm = 0.004995 %

    ^now those are really great number... I guess I just have to save more cashish.

    Is SACD truly better than CD ???

    I guess the way the question was originally phrased, it could have better been illustrated by saying... can you see the moon better with made by coca cola or glass made by Zeiss.

    if resolution means anything to you, you have your answer. I realize resolving power doesn't cure cancer, but it does ensure that when you look at it, the least amount of extraneous material, or loss of information, is... well... lost, or worse yet, interpolated.

    No CD I own, and I own at least a thousand, comes close to my SACD's... it's not like the cd's lack definition or even richness, but the sacd's take it to another level... specifically in fullness and smoothing out harshness. this has come from back to back playing on the same system... albeit not a great highend system(all SS using a PS3 as playback, not all PS3's are sacd compatable).
