This one is timing-sensitive in the right way: older power conditioners can be a mixed bag, but at A$220 it lands far below your recent comparable market, so the price reads as a strong bargain rather than a speculative ask. Against the anchor set, it sits well under the A$1,886 25th percentile, so there’s plenty of room for it to be a good buy even if it’s not pristine.
If the unit is healthy, a power filter like this can be a worthwhile low-risk upgrade for a modest system: cleaner mains, fewer nuisance issues, and often a bit more stability for source gear than you’d expect from the outlay. The main things to check are practical, not philosophical — confirm the sockets, any switch or breaker function, and whether the listing includes the original box or cable if that matters to you.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Consonance, a brand under Opera Audio, traces its origins to Beijing, China, where it was founded in 1994 by Shi Hui Liu. As one of China's pioneering high-end audio manufacturers, the company began with tube amplifiers and evolved into a family-run operation that has expanded over three decades. Its philosophy of "Simple. Human" underscores a commitment to original designs and international appeal, with products distributed in over 30 countries.
The brand specializes in a broad range of hi-fi components, including tube and solid-state amplifiers, turntables—where it claims to be China's first high-end producer—digital sources like DACs, electronics, and accessories. This complete line supports full music reproduction systems, blending traditional vacuum-tube warmth with modern precision engineering.
Consonance holds a niche position in the medium- to medium-high-end market, appealing to audiophiles seeking boutique Chinese craftsmanship at premium prices. While praised for innovation and global reach, it remains somewhat obscure outside enthusiast circles, with occasional critiques on build quality tempering its high-end reputation among discerning buyers.
