Spark
Don't let the diminutive stature fool you, the svelte Audio Physic Spark performs far beyond it's modest dimensions. The soundstage is positively huge, offering the holographic presentation that has made Audio Physic elite among speakers. The beautiful and graceful cabinet design has purpose - the sidewalls are non parallel, dramatically reducing internal standing waves.
Top quality drivers and crossover components compliment the outstanding construction quality and fastidious German attention to detail.
"The overwhelming majority of speakers possess some degree of 'character,' for good or ill, which gives the reviewer something to write about. On this occasion though, the standard of neutrality is so high, there's little to criticize. More than most, the Spark seems to 'disappear,' acoustically speaking, leaving just the music spread out between and around the speakers. Imaging is beautifully precise and well ordered, with tendency to 'hug' the speakers. It also delivered good depth perspectives and a pleasant airy spaciousness that was particularly effective with naturally miked classical material." Hi-Fi Choice - Best Buy
"We found ourselves listening to the first act of Rosini's Barber of Seville on a Philips recording by The Academy of St. Martin in the Field, directed by Sir Neville Mariner. The imaging as well as the wide soundstage achieved by the loudspeaker extends far beyond what you might have expected when taking into account the "small" dimensions of the Spark. Just listening to first act gave us some idea of what the loudspeaker is capable of in terms of voice reproduction where it radiated a high amount of vitality and delight in playing. The Baritone of Count Almaviva came through superbly and was rendered elegantly with all its richness and depth in our listening room. The crazy melee and swelling of voices which accompanies the musicians' retreat at the end of the first act was reproduced with unbelievable realism and dynamics. If you shut yours eyes you could literally feel the haste with which the actors noisily left the stage." Haute Fidelite
