Apollon NCx500 ST Power Amplifier Purchased this Stereo Amp on June 11, 2024 from Apollon and stopped using it late July. This amp have the upgraded input buffer: Sonic Imagery 994 Original receipt available. Paid $3k including import duty and tax. It doesn't come with any power cable. Compared this with a pair of my Benchmark AHB2 power amps and couldn't hear any audible difference. check my other ads as I have put the ahb2 for sale. No longer required as I was very impressed with the Apollon hypex ncx500 stereo amp and ended up buying the same hypex ncx500 in Mono for my fronts and sep
Ambitious asking price at AUD 2,000 for a used Apollon Audio NCx500—likely the compact NCx500 ST stereo model with dual Hypex NCOREx modules (380W/8Ω, stellar 137dB SNR, 0.0002% THD). New ones retail around AUD 2,500-3,000 equivalent, but typical used market in decent shape sits at AUD 1,200-1,600 locally, factoring recent 2023-2024 releases and solid ASR measurements. Unless it's pristine with full warranty or rare custom buffers, push for AUD 1,400 max; otherwise, shop around forums for better deals.
Before biting, verify the input buffer op-amps (e.g., OPA1656) aren't swapped or degraded—easy tweak point that alters sonics—and confirm original power supply (SMPS1200A700), trigger cable, and manual are included. Check for heatsink rash or binding post wear from heavy use, and test all gain settings (12.8-29dB) for clean output into 4Ω loads. No major failure reports, but age over 2 years warrants a burn-in listen.
