"Dynamics were powerful, yet subtle when required, and fast. The quietness Iíd 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."
"Orchestral color was just gorgeous, with fully developed harmonics making the RLP sound rich and natural. I recently auditioned a DAC that made it difficult to distinguish between the solo violin and cello. The PRE550A had no such problem. Orchestral violins had a rich sheen, with abundant high-frequency extension."
To hear how the YBA reproduced a solo instrument, I cued up Ottmar Liebertís 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 Liebertís 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" "YBAís 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."
"But what jumps to the ears, it is the absence of subjective coloration of IA350. It was never the impression of having to deal with a sound repetitive but to a great diversity of tonal colors and a guarantee of transparency and definition. The attacks are effortless."
"It is more close to the instrument of music as the instrument of measures, and it is this which makes all the difference." April, 2016
Digital Cable: I2S • Loudspeaker: Harbeth 40.1 "YBA sound is a close, powerful sound. It is very open and we have a lot of information in advance of the band. But as much it happens in the middle and bass. It is hard not to talk about the advantages treble. Just one listen and one has the impression of wealth of detail and density transmitted in the information."
"The more that the sound is fed close to us. It is this type of communication in which everything is at your fingertips, strong, dynamic, very true. In this sense, we look at everything from the first row, rather than from a distant perspective."
"It's just that YBA adds to the incredible purity. It is as if to get insight into the recording, as if between the speakers appeared more and it had it all: detail, space, attack, dynamics."
