amp or amps for Polk SDA 1 & SDA 2

I have the SDA 1's as well. I have ran them with NAD, Carver, and Krell. I am now running them with a Pass Labs X-350 through a mcintosh C2200 Tube Preamp. Best set up so far. All three prior were integrateds. I actually bought the X-350 and Mac pre to run through ML Ascent i's that are on order. Now I am beginning to wonder if I should not just keep the SDA 1's. They have never sounded so good. I am pushing a ton through them and they have totally risen to the occasion. Hard to belive that these speakers are now 20 years old. I am hearing Billy Joel hit notes on his piano that I have never heard. Listening to "And so it goes" as I write this. I am finally at a point in my life where I can afford some better stuff and kept thinking the speakers should be replaced first but I am having serious second thoughts. Pass and Mac are a pretty darned good combo for the Polks. Oh and I am using a Shanling T200 with a level one mod including WE 396A tubes. Transparent interconnects and XLR with MIT speaker cables. Just another point of view for you to consider. Best of luck with your system.

There is no doubt that the Polks were made to be feed like hungry bears! At 4 ohms, I am pushing 700 watts per side into them and they love it! If I ever get the nerve to push hard and play something that would dip into the 2 ohm realm, I can't help but wonder what they would do with 1400 watts per side! Djbnh, what cables are you using? Sounds like a really nice set up. You know what they say about speaker cables, they are like tires on a sports car. Bad tires and the car won't handle, good tires and you'll never want to stop driving it. I went ahead with the order for the Ascent i's as the price my dealer gave me for new was better than what I have found on the used market. I also just found out that ML is going to discontinue this model and replace it with something else. Now I know why I got such a great price at least. I am thinking that the SDA 1's would make great rears in a HT setup with the MLs up front. I guess I should start looking for another PL X-350? Oh gawd, help my checkbook...LOL
