To get the best out of the DHT 2a3 amp, you have to use very efficient speakers(more than 105db/m) like altec, we or jbl. I'm a DHT 2a3 amp user too, I using the DHT 2a3 only for the mid/high in my bi-amp altec horn speakers.
If you need to buy 2a3 tube, please let me know since I have some spare RCA 2a3 tubes.
