My Wright 2A3s performed great on a variety of speakers, most recently a pair of B&W CDM1-SEs. I changed out the stock 2A3 to Sylvania NOS tubes. A modest improvement in sound resulted. I'd keep them and enjoy them. Put the money into a fine DAC, or branch out to different speakers, or a sub. Enjoy the Wrights!
Upgrading my SET amplifiers?
I am very happy with my Wright Sound 3.5/Lamhorn/Lowther EX 4 combo, but I know that the amps can be improved. I was looking for a Berning Siegfried, but nobody wants to sell this amp used and new is not longer available. I’ve read good things about Art Audio, Wavelength, Exemplar and the like, but I want to know from people who actually own those amplifiers or other very good SET amplifiers. I am willing to spend $ 3,000 / 4,000 in this upgrade. If possible, I prefer to buy used. Your help is greatly appreciated. Pablo.
