Electrical Disclaimer Description
This listing is for an ATC SIA2-100 stereo integrated amplifier with original packaging.
I purchased this as ex-demo from Terry of GC HiFi in October 2022 (original receipt available) and would conservatively rate it as in very good condition.
This amp comes with 3 digital inputs (coax, toslink & USB), two pairs of analogue RCA inputs, stereo speaker outputs and stereo line output (which I used for a sub) and puts out 100W into 8 Ohms. A truly versatile and well built partner to any speakers requiring moderate power.
ATC is well known for the quality of its powered speakers, and so it is especially suited to run the passive ATC standmount range of the SCM7, SCM11 & SCM19. I am also selling a pair of ATC SCM11 speakers and an ATC C1 Mk2 sub, which I used exclusively with the SIA2-100. The price is firm, unless you decide to buy all three components together as a system.
Selling because family life makes headphone listening far more practical for the foreseeable future.
I'd prefer this to be an in-person transaction, but live many miles from the nearest city. For those from Brisbane or the Gold Coast we could meet up in Warwick, or if the buyer is from Sydney, Murrurundi is this halfway point. Shipping can be arranged at the buyer's expense, but must be fully insured.
