2A3 amp and Spendors?

I have the Spendors (think they are great). I have not tried with 2A3, but have used 300B SE. It was sufficient about 95% of the time in my medium sized room, backing off the gain and listening a little quieter than I would have liked (I listen normally at moderate levels) made the amp usable with the rest. You are talking about 3 watts to the 300B's 10 watts, so my suspicion is that you are probably right on the cusp. This is a situation where I would try and borrow the amp you are considering or a similar amp to find out for yourself if you can live with it. Since SE amps are such a specialized item, I would try to find a dealer who would let you borrow one for a few days (give your dealer a break, he needs his "demo", offer to borrow it on Sat at closing time and return Monday and take GOOD CARE of it!). The other alternative; I believe Wright Sound (who makes some highly regarded amps) offers a trial period and makes a 2A3 amp, check his website for details (I have no connection to them...).

Didn't think you were knocking the Spendors, Clueless. And a 2A3 would not be MY first choice generally for an amp for the Spendors. But that's what Wda specifically asked about. The numbers say 88db/eff. plus 3db (pair of speakers) minus a little (you will be listening further than 1 meter away!) meaning a 3 watt amp will play about 90db peaks which to me is reasonably loud, but you can certainly run out of steam sometimes. I use, among others, a Leak Stereo 20 (P-P 6BQ5's, about 15 watts or so) and don't run into trouble. The Spendors fortunately have a fairly benign impedance curve (mostly over 8 ohms) so they do lend themselves to tubes. 300B's at 10 watts will do about 95db or so which is a little more like it. But your mileage may vary! Kevin
