Wolfgang Kemper put our SPL Director, the new DA converter and preamplifier of the Professional Fidelity series (Pro-Fi), to an extensive test. A really worthwhile review, which besides technical informations also is a nice introduction to the world of “Professional Fidelity”. Thanks to the metaphorical descriptions of audio impressions, the difference between the Pro-Fi series and conventional Hi-Fi units becomes clear:
“The magic word is Voltair.”
“The light and open manner in which the SPL (Director) operates is astonishing. It doesn’t exaggerate in a dissecting way but provides a nice warm sound for every song. It makes ‘Quiet Winter Night’ of Hoff Ensemble (Flac 24/96) sound colorful and punchy.”
“The Director never gets stressed. It is free of that – and does not manipulate the audio material in any way. It sounds thoroughly honest and operates in a completely smooth and relaxed manner. Its dynamic characteristics and its diversity are extremely good. It literally draws on unlimited resources with plenty of headroom left. This is exactly what SPL promises, thanks to the Voltair technology.”
