ATC CDA2 & P1 - Hi-Fi i Muzyka review
  • Best Stereo system Hi-Fi i Muzyka, 2014 Award.
  • The sound is characterized by neutrality and linearity study . The transparency reminds of headphones, and the dynamics gives the impression as if possessed kilowatt .
  • The sound is so realistic and has the momentum that we feel like at the concert. Not only did this in concert halls, but also rock , just before the stage. Impressions are spectacular, and the return to "normal " equipment - often painful.
  • The price is ... low and does not reflect the class British set.

ATC CDA2 & P1 - Hi-Fi i Muzyka review
  • First impressions are dynamics, mass and energy of sound. Brute force reveals terminations at each jump the fan sound. It seems that there is no possibility that the amp ran out of steam. 
  • These 150 watts creates a downright shocking effect, overgrown make my Mac MA7000. Concerts rock, symphonic orchestra tutti, electronic wall of sound Massive Attack - all for ATC as the bull potato. 
  • The duo swallows every challenge and before we thank you for such an impressive performance, poured more blows. Likewise, the sound instantly expires; is controlled just perfect. These things we hear from MBL-a monoblock and other horribly expensive power plants.ATC may only offer less sophistication. Playing for it normally. No frills, colorations or building unnatural, though pleasing to the ear of effects. From the beginning, you may not like a rave, but parting with it will be painful. Once you hear natural-sounding instruments, will be difficult to go back to the mystified version.
  • You can catch a little Audio Research accurateness and indifferent Spectral precision, but after a while I feel that comes to the fore another priority: transparency. 
  • Regardless of the degree of complexity and clutter instruments, the sound is drawn on graph paper, with clear contours. It can therefore be a heavy metal guitar extract individual rows, although others also play in the same band. 
  • Easy to fish will squeak of chairs or other attractions, which usually remain hidden. ATC, as perhaps no other amplifier, showed the work of a piano pedal mechanism on our starenkim sampler. MBL has the same advantages, but I always try to stay smooth and velvety. Meanwhile, the ATC is not afraid to sharply sip or make a noise. Perhaps some consider it as a disadvantage, but I see this as a boon inventory.flawlessly system also shows the quality of the recording. Interestingly, many of the classics from the 60s and 70s can sound surprisingly fresh.
  • CDA2 Player - phenomenal. Both because of the sound, as well as on-board preamp. For the active column is a complete hi-end system.

ATC CA2 - AV Mentor review
  • Midrange offered a sense of fullness, and they were transparent and detailed. The listener had always a feeling of being near the orchestra and the voices, both the solos and the choir, were rich and quite realistic both in size and character. The high frequency part of the spectrum offered.
  • CDA2's preamplifier section proved to be transparent, with low noise levels and therefore capable of quite good dynamics. Stereo imaging was at the same level as when listened through its digital part and the feelings of easy listening, the fullness and the realism were also there. The final result is that this is not a casual preamplifier stage, included only to justify the integrated form of CDA2, but a well designed, full spec preamplifier.
  • Build and sound quality are very good and the price is more than tempting. In the end, this is a piece of equipment of great value for money.
