Passion "Amp 650" • Output A has a high damping factor which will provide a very clear sound • Output B with a lower damping factor will provide a ‘sweeter’ sound (more like a tube) • 9mm Aluminum bottom plate with mechanical ground path • Transformer: 1000 VA C-core grain oriented pumped under high vacuum for 48 hours at 100 °
Passion CDP430 + IA350 at 2014 Munich by Yves-Bernard André Viewable in 1080HD & 720HD
All have 9mm Aluminum Bottom Plate to enhance Mechanical Ground Path
"Dynamics were powerful, yet subtle when required, and fast. The quietness I’d already noted let me hear a lot of detail -- real detail, not the fake detail created by goosing up the high frequencies. Speaking of the highs, they were open and extended, with plenty of sparkle."
"To hear how the YBA reproduced a solo instrument, I cued up Ottmar Liebert’s One Guitar (24/96 FLAC, Spiral Subwave/HDtracks). The detailed realism the YBA PRE550A retrieved from this high-resolution recording was amazing.It reproduced the sound of Liebert’s guitar incredibly well -- not only the notes, but also the extraneous noises inevitably produced by a guitar being played by a master. Notes were harmonically complete, attacks and decays were extremely lifelike, and some of the initial transients were startling in their forcefulness" "YBA’s Passion PRE550A lived up to its French origin by producing unfailingly beautiful, realistic sound. Its extended highs were gorgeously smooth, with nary a bit of peakiness. The midrange was very detailed and harmonically rich -- little to grumble about there. Very highly recommended."
