Over 20,000 Spark amps have been pre-ordered worldwide directly on the Positive Grid web site. Due to the large number of orders, Positive Grid have a significant delay manufacturing and supplying that many units. Not a single Spark has been sent to an Australian consumer yet. All distributors globally are not expected to receive stock for local dealers (Australian music stores) until late April at the earliest.
We do have a Spark pre-production sample in our Melbourne office and we can confirm the amp is amazing, so it's worth the wait. Australian street (sell) price for Spark is expected to be A$499. (USD $299 / .67 + GST)
