Jackal Posted June 14, 2010 Report Share Posted June 14, 2010 Hi all,Hope everyone is doing well! I have been trying to get my first tube amplifier, but want to make sure they can handle the wpc of AR speakers!I'm trying to decide between the AR-2ax, AR-5, and AR-3a. I would like the AR-3a, but powering the beast is a worry. I've been looking at the Dynaco ST-70, and Fisher model 400, 500-C, and 800-C as possible choices, but wanted to hear what the forum's experience is with driving these speakers with tube amps.So, what combos have you seen in your lifetime? Thanks, -Jack Link to comment Share on other sites More sharing options...

Thanks, -JackI'm not familiar with the models you mentioned but as a general rule, AR speakers require a large amp and can be difficult to drive. My recommendation would run in the direction of a tube preamp and a solid state amp, which is what I do with my AR90s. Link to comment Share on other sites More sharing options...
Tekker Posted June 22, 2010 Report Share Posted June 22, 2010 If I recall the ST-70 puts out about 35w per channel which is about the minimum recommendation AR made for the 3a I believe. Probably OK at fairly low volumes. I drove mine with 40wpc for a while and they sounded OK. Drove them with 100 wpc and they were much better, but they really shined at 200wpc.Good luck,Bill Link to comment Share on other sites More sharing options...
