Topping A70 Pro Headphone Amplifier I doubt this amp needs much introduction but here is the link to the product page- https://www.toppingaudio.com/product-item/a70-pro This one was purchased by the original owner 10/1/24 from A2A here in Perth. I'm the second owner. The Topping has been loafing along 'driving' a pair of Audeze LCD-2 Closed between -40 and -30dB on low gain. It's been a great foil for the darkish sounding Audeze, a robust and detailed fatigue free sound. The volume control deserves a special mention, so linear and precise in its ½dB increments. Makes it easy to dial in
Condition is unknown, but at A$540 this lands just under the A$550 25th percentile and well below the A$575 median, so it reads as a strong deal on your own comp set. It is not bargain-bin pricing, but it is cheap enough to look attractive if the unit is clean and fully working.
That makes sense for a well-regarded solid-state headphone amp: the appeal here is strong drive, low noise, and the kind of control and headroom that suits demanding headphones better than many smaller amps. If it includes the original power supply and the casework is tidy, this looks like a sensible buy rather than a project; with a headphone amp like this, a clean, complete listing at this price is usually the sweet spot.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
