I have an old set of of SDA-1Cs. Can I run them with an Yamaha RX797 receiver or is that underpowered for those speakers?

    Yep,, careful with that volume though,, as you don't want to "clip" the amp.If you plan on keeping/using them,, a higher current/power amp would be in order. Good luck and have fun.
    JC approves....he told me so. (F-1 nut)

    Shouldn't be any problem. The 797 spec sheet mentions "4 Ohm rated" X 100 per channel. I drove mine for a while with a 75 watt HK although at admittedly lower-type music volumes but some of the movies got pretty loud. It should be just fine unless you play it for the neighbors. :rolleyes:

    The 1C's present a demanding load and while the receiver will produce sound it's not the best long term solution unless you want background music. A separate amp is the best solution but you can "get by" with a receiver at low levels for awhile.

    Also FYI, I have 1C's so I am speaking from experience not a spec sheet. :)

    I'm with george, heiney and Ron. I have the same receiver. It is a 2 channel workhorse, but for those power hungry speakers, you're better off with an amp.
    I agree with the separate amp camp. I have Odyssey mono extreme amps (need to make sure you use the correct Polk IC iteration when running monos), and find the Polks breath so much easier and with great finesse when powered this way. Good luck with your decision making.

    You should try to get ahold of a 200 wpc amp for a day (beg, borrow, audition) and listen to the improvement that a good amp makes. The larger soundstage and tighter faster bass more than justifies the expense.
