ATC SIA2-150 Mk2

• SIA2-150 showed its character from the very first bars, demonstrating a remarkable drive in the performance of the soundtrack for the film "Flashdance", namely - "Maniac" by the authorship of Michael Sembello himself. It seems that the whole space is permeated with energy, hidden before that in the 1983 record, but, as it turned out a little later, this is just a translation of the emotional message hidden in the material.
• It seemed to me that the amplifier is more inclined towards large musical forms, the recordings of symphonic compositions in its execution amaze the imagination with the scale of the recreated picture.
• Rock concerts are listened in one breath to the “needle on the escape track”. The choir recordings amaze with amazing detail and a sense of ownership.
• As for the reconstruction of the stage space - it is at its best, ut to a greater extent depends on the connected speakers... With a successful selection of speakers, the picture becomes almost perfect.

• Stereophile "Class A Recommended Components 2013"
• ATC's beefy (44 lbs) SIA2 integrated amplifier ($5000) puts out a claimed 150Wpc and is hand-built in the UK. It has five RCA inputs, but no phono stage, balanced inputs, or onboard digital capability requiring USB or S/PDIF connection; in two words, it's old school. And I love it.
• The SIA2 exhibits all the virtues of a first-quality solid-state integrated amplifier.
• To sum up the SIA2: excellent performance, good value for money, and a great match for ATC's SCM 40 speakers.
• And Monheit's voice was just plain wonderful to listen to—the ATC is a great amplifier.

ATC SIA2-150 Mk2

• First, I listened for a few minutes a Mac (n.r. McIntosh MA7000), to have a reference point, and then dived for the cabinet to change the call. The first second brought a big surprise. I had to make sure that all cables definitely hit where it should be, because the speakers flowed focused like a laser wave and strong as real absinthe energy.
• If not enough power, it will be loud, but the music runs out of purity and resolution. But not here, because next to the pulsating
  energy most impressive detail and precision can be heard. Every little thing is served with great care, is a separate event.
• This amp plays differently than McIntosh MA7000, which in its price class (two times higher) I consider to be one of the few patterns. But I put an equal sign between them.

• This amp allows for a wonderfully open soundstage through which detail can shine. The choir in 160 BPM, from the Angels & Demons OST, can sound muddied and grubby through poorer amps, but the ATC opens up the track, bringing in real clarity and insight.
• The amp displays great power, drive and determination as the track builds up. Not only are the edges of notes superbly defined, but there's great texture and feeling behind each one.
• The ATC produces a spine-tingling connection between the listener and the music.
• Sturdy design
• Hugely emotive and convincing sound
• Sensational timing and dynamics

ATC SIA2-150 Mk2

• Its sonic signature is an unwavering midrange forthrightness and fluidity. Its neutral to warmer tonal balance allows for the most critical listening, yet doesn’t cross the threshold into the starkly clinical. Musical fundamentals and overtones are expressed like continuous liquid waves of energy.
• Bass response is excellent with precise pitch and plenty of slam"
• Perhaps the most impressive aspect of this amp was the wide net it cast in resolving soundstaging and imaging.
• Like the ATC, the Plinius throws its weight and balance where it’s most appreciated—in the midrange. The key differences are the slightly drier character and tighter lower end of the 9200.
