    "Micro Bamboo Project" : 3E Audio 260-2-29A Stereo amplifier + Micro-Audio PSU

    I am in France ) $ 280 is about 260 euros for a 106db Sinad amp. For me it is a bargain if you have some DIY skills )

    A Stereo version with a 48V/10A PSU would make everyone agree....

    A well done TPA3255 PFFB Mono should give (with a 500W PSU @ 48V) @the knee : About 190W @ 4R About 100W @ 8R If you want to get an idea, you have to compare chips that are comparable to each other. In this case, this Fosi Mono has two main competitors: - 3E Audio 480-1-29A Mono TPA3255 /...
