A few great examples but highlights:
Turntable 1998: Garrard 401 with SME arm, free, someone put out with their rubbish, no lead but Len Wallis Hi Fi in Sydney found me an old one, also for free.
Amplifier: current Cayin CS55a, list $3700, closing down sale special $1900, Denis White Adelaide. Given so much soundstage with Audio Physic Sitara 25's.
Speakers 2005: Audio Physic Yara 2, list $2700, stored in wrong box for 5 years, never used, Sydney Hi Fi $1000. Replaced 20 year old Royd Doublets.
Headphones: current Focal Clear list $2200, special from Addicyed to Audio Adelaide, $800. Astounding. Was never a headphone user, now my component of choice.
Streamer: current Lindemann Limetree Bridge, list $1450, sale $1000, Hi Fi Collector, Adelaide Hills, nice great combination with Denafrips Ares 2.
There are always bargains out there.
