As the late (And great) Al use to point out , when you bridge an amplifier the speaker impedance load (As seen by the amplifier) is halved. So a 4 ohm load becomes 2 ohms and so on.

Gave up my SET----looking for moderate to higher power replacement options
@charles1dad As @twoleftears suggests, my bet is on the AGD amplifiers as the most SET sounding class D design (GAN-based). I'd love to hear them. They certainly want to convince us that they care about SET musical characteristics with the design, and one dealer advertisement states that SET people do like them (https://www.youtube.com/watch?v=2PKSlTODkJ0). Unfortunately more than double the OP's budget. |
And thanks for channeling @almarg for the technical reminder about why the Benchmarks would struggle when in bridged mono mode. It makes total technical sense, but is ironic that when configured to deliver the most power, they also lose the ability to deliver the needed current into low Ohm loads. Unfortunately this is likely the exact kind of case in which one would actually need the additional power. Watts are cheap... until they aren't. |
