This gallery features some of the work done by the Hifisonix DIY audio builders’ community. If you have any pictures of your build, feel free to send them to me, and I’ll post them up here. The gallery covers power amplifiers, preamps, line stages, and phono amplifiers.
Anand Raman, who hails from North Carolina in the US, built a pair of ax-Amplifier mono blocks along with fellow builder Steven Edwards, who lives nearby. Anand, like Steven, spared no expense, and the result below showcases his stunning build. Since the 4U monoblock chassis’ were slightly smaller than the 5U version, both Anand and Steven tuned the bias current down slightly to ensure the heatsink temperature on sustained use did not exceed the recommended upper limit of 65°C. Anand used a Torroidy transformer, and protection and PSU boards from other DIY vendors on diyAudio.com.
Below is Dule’s fantastic nx2-Amplifier build. Dule hails from Serbia, and used the new Hifisonix REP (aka ‘ripple Eater Power Supply) for each channel. All the necessary cabling is tightly twisted, and he and his system-listening buddies are very impressed with the sound. (See the nx2-Amplifier project page for a review of this amplifier and Vojin’s build).
Here are some pictures of US-based builder Steven Edwards beautiful ax-Amplifier build. He elected to go with mono blocks and used the mono block housing from Modushop. Steven used a Torroidy power transformer and PSU and protection boards from other DIY suppliers on diyAudio.com.
Here are some images of UK builder David Kenyon’s immaculate kx2-Amplifier build. David used a Modushop Mini Dissipante housing and Micro Ripple Eaters for each channel. David reports that the amplifier is dead quiet with his ear in the speaker cone, and that’s down to his good wiring practice of twisting the PSU cables tightly and cable tying them to ensure radiated noise is kept to a minimum.
