One look at this amplifier and you know it is a very well made product. The fit and finish is superb, and in fact the pictures do not do is the justice it deserves, as it really is a very beautiful amplifier to behold.

The SIA2-150 offers only unbalanced RCA inputs and there are five inputs, plus record out, pre out and sub out, as well as a 6.3mm headphone output on the rear panel. Binding posts for s single pair of speakers will take both banana and spade connectors.

It will come as no surprise that this amplifier is the perfect match for ATC loudspeakers which are notoriously power hungry, and the SIA2-150 easily drives all models. A remote control offers complete control of the input selection and volume.

Many reviews are around on the net for this amplifier, and all sing the praises of this very fine amplifier, some excerpts appear below. You can however always come in for a demo!

{gallery}SIA2-150{/gallery}"We’re constantly praising the natural, emotive tone of ATC’s speakers and the SIA2-150 sounds like it has been cut from the same cloth. This amp allows for a wonderfully open soundstage through which detail can shine. The ATC produces a spine-tingling connection between the listener and the music, not just with rock, but whatever your musical poison. ATC has set the bar extremely high with the sensational SIA2-150, and that's no mean feat…"
What Hi-Fi

"The SIA2 exhibits all the virtues of a first-quality solid state integrated amplifier. It costs US$1500 more than the Luxman L-505u and offers fewer features. But the SIA2 is even more authoritative-sounding than the entry-level Luxman, with a more 'modern' less 'retro' or 'flattening' presentation, an apparently lower noise floor and more resolving power...To sum up the SIA2: excellent performance, good value for money (US$5000), and a great match for ATC's SCM40 speakers."
Stereophile

"Like only the best amps I’ve heard the ATC clings tenaciously to a decaying reverberant field, permitting the ear insights into the recording process that few other integrated amps can match....For all its retro-stylistic flourishes the SIA2-150 is a thoroughly modern instrument that quickly gets down to the business of making music. In my view, fidelity to the source is built on balance—the way sonic criteria interlock like fingers to form a powerful fist—and so goes the SIA2-150. Powerful, dynamic, and virtually colorless, it’s major league all the way. In case you haven’t already guessed, the SIA2-150 is my kind of amp."
