I own a pair of Legacy Signature III speakers, I’ve owned them for seven years. I find them a very good value in the areas of over all sound, quality drivers and parts and excellent craftsmanship. Before someone out there blasts what I just said I’m aware that there have been several threads over the last year stating that inferior drivers and parts were used including less then satisfactory workmanship. All I can say is if that is the case my speakers are NOT like that. I have been very pleases with them.
I have driven them with every thing from a 5-watt single ended pair of monoblocks (tube) to a 40 watt SS receiver to a SS high current 400-watt amp. I will admit the Signature III’s sound better with a high current amp with at least 150 watts into 8 ohms, off course the speakers are 4 ohm so it’s to your advantage.
The website that Ezmeralda11 gave in the post above is helpful (an example of how Audiogon members help each other out);-)
I hope you find this helpful, feel free to email me with any specific questions.
