This extraordinary reference receiver is suited to quad in-ceiling DTS: X™- and Dolby Atmos®-ready layouts with mammoth power to drive front and rear floorstanders with thrilling dynamism. The TX-RZ1100 leverages Onkyo-tuned high-current architecture with sophisticated digital-switch
A$1,280 is ambitious for this model unless it’s unusually pristine with proof of service and extras. The available used comps I found sit far lower, with recent asking prices around A$145–A$200 equivalent, so this listing is well above the normal market for an Onkyo TX-11.
That said, the TX-11 is a tidy little vintage receiver/tuner, and these are appreciated for straightforward, musical two-channel use rather than brute power. It’s a better buy if the unit is clean, fully working, and complete with the original knobs, feet, and documentation—but at A$1,280, I’d want a truly exceptional example and detailed confirmation of condition before paying up.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Onkyo traces its roots to postwar Japan, founded in 1946 in Osaka by Takeshi Goda, an engineer at Matsushita Electric who envisioned high-quality Japanese loudspeakers. Initially established as Osaka Denki Onkyo K.K., the company began production in 1948 with the acclaimed ED-100 speaker featuring a 25 cm driver, quickly building a reputation through LP concerts and innovative designs that resonated with audiophiles.
The brand excels in premium home audio, renowned for AV receivers, hi-fi amplifiers, and surround sound speakers that deliver exceptional clarity and power. Its portfolio spans turntables, DACs, headphones, and cables, bolstered by acquisitions like Pioneer's home electronics division in 2015, enabling cutting-edge integrations such as internet radio and high-resolution streaming.
Onkyo holds a solid mid-tier position in the hi-fi market, prized by discerning buyers for reliable performance and value rather than ultra-high-end exotica. Despite bankruptcy challenges in the late 2010s, its revival under new ownership preserves a legacy of technological innovation and pure sound enjoyment, appealing to both vintage enthusiasts and modern home cinema setups.
