    How are power amps priced on besides wattage, is there such thing as good n bad tone if the power amp isnt producing the tone, jsut making it louder? Like is a little nady ganan sound worse then a nice eden power amp?

    Well, power is power, and there's no bad power unless you have too little, or you mishandle too much. Yes, more watts costs more. So does quality manufacturing.

    Tone is not included in your power amp purchase. As you said, the power amp just amplifies.

    this could get ugly quick
  4. Unfortunately, debates can generate quite a controversy!

    In the 60's and 70's transistor amps were just being developed, and many solid state amps did indeed sound "harsh". Now, though, amp design has progresed quite well. The ideal power amp has been called " a straight wire with gain" meaning that the amp imparts absolutely no coloration to the incoming signal....what comes in, goes out, only louder. Even cheap designs nowadays can do this part fairly well, certainly some designs are better at avoiding coloration than others though.

    IMHO the main differences between cheap versus high-quality amps now will be (in addition to the slight sonic differences):
    -quality of construction
    -stability under difficult speaker loads (such as highly reactive speakers)
    -performance of protection circuits
    -presence/absence of extras like filters, parallel operation, or bridging
    -weight (influenced by power supply design)

    Tube amps of course are a different breed altogether. :D
