Consonance Reference 5.5 Integrated Amplifier (Valve) Very very rare to find in used market. A very high quality and beautiful sounding 300b parallel SET amp from Opera Consonance. It uses 4x 300b as power tubes, 2x 7119/ECC182 driver and 1x 12AT7/ECC81 pre stage tube.All the tubes that come with the amp are top quality - vintage Electro Harmonix Gold 300b, and all 3 small tubes are vintage Amperex.I have had this amp for few years and it has never skipped a beat. Everything works perfectly fine, no hum/noise even with 92db+ speakers. Sounds absolutely amazing like how a 300b amp should sound
With unknown condition, the AUD1,650 asking price for this Consonance Reference 5.5 valve integrated amp looks like a potential bargain against our database of 10 recent comparable listings—median AUD2,462, with 25th percentile at AUD1,630 and 75th at AUD2,634. That's squarely at the low end, but the lack of condition details screams caution; pristine examples rarely dip below AUD2,000, so this could be a steal if lightly used, or a money pit if neglected.
Before biting, verify the output tubes (common EL34 or KT88 types wear fast—expect AUD300-500 to retube) and check for hum or channel imbalance from aging coupling caps, a known weak spot in these Chinese valve designs after 10+ years. Insist on the original remote, manual, and power cord; missing bits cut resale value hard. Test with your speakers to confirm that sweet midrange magic.
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.
