"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."

"It has incredible grip and authority, being able to go surprisingly loud without ever losing its composure or letting loose the speakers attached.
Tori Amos being placed perfectly between my speakers and sounding truly lifelike as she sang the heartfelt break-up song Blood Roses. The accompanying harpsichord sprang from the background as fast and as jagged as Tori's words.
Separation of detail is impressive, with tracks displaying clear space in terms of depth as well as width and solidity.
With its superlative build quality, finish, aesthetics and ergonomics, this amplifier is a real class act. Then there's its seriously good sound quality and of course its undeniable flexibility you get from its various inputs."

We HIGHLY recommend the music of Margriet Sjoerdsma
Her tribute album to the music of Eva Cassidy is a very special treat.

The sonic signature of this amplifier is very pleasing, itís little cooler sounding than my Yamaha, and has more of the rhythm and timing that I associate with Naim products, but with a more three dimensional presentation.
The longer it was here, the more I enjoyed it.

My Harbeth SuperHL5+ 40th Anniversary loudspeakers were absolutely singing, whether I was indulging in hard rock at window rattling levels or rather more laid back classical music, I felt a tremendous emotional and indeed physical connection with the music.

The IA350 offers 115 Watts into an 8 Ohm  load. That translates into effortless delivery in a typical UK lounge. Whether playing vinyl or little silver discs, the music simply flowed. Music streamed from a Naim NDX, fed a diet of FLAC files from a Naim UnitiCore which is also here for review, really came alive. The gap between digital and analogue sources is narrowing!

Anyone with the budget and a desire to get real joy from their music collection really should short list the YBA Passion series.
