Een voorproefje: The Quad 405 and 405-2 are almost identical, compact, heavy, power amplifiers. Both punch out 100 watts per channel, into 8 ohms. Where they differ is in their ability to deliver current into lower impedances.
Specifically, Quad modified the current limiting circuitry of 405-2 to be a little less aggressive. There’s a wider power envelope with the 405-2, allowing it to better drive lower impedance loads. If you own current-hungry speakers or those with a nominal 4 ohm impedance, a 405-2 is the better option.
Quad also implemented various iterative improvements over a long period. In my opinion, the later amplifiers sound and perform slightly better. If you are interested in more technical detail, I recently overhauled a Quad 405-2 and you should also check out the ‘Further Reading’ section at the end of this article.
