My only concern is the vulnerability of the GaNTube, exposed and waiting to be smashed or knocked over. I would ask AGD to fashion a cage as per the smaller AGD Audion, but obviously more in keeping with the Gran Vivace’s modern look, rather than the Audion’s ‘steam punk’ plumage.

Most listening was undertaken sans preamp, as I’m currently fixated on sources with output controls, eg, most tape decks, phono stages for LP-only systems, etc. And why not? It eliminates all that circuitry, a set of interconnects and shortens the path; the only sacrifice is extra inputs. As the Gran Vivace has two selectable inputs, I fed the Otari MX5050 directly via XLRs, and used the single-ended input for other sources. Also, the partnering Andante preamplifier never made it past PM‘s lab tests, it proving faulty and was rejected.

Rosewood is eclectic, too. Varying solo instruments including piano, melodica, Spanish guitar, and even accordion lace themselves well through what appears to be a soundtrack full of purpose. Unfortunately, I have not seen the movie. Regardless of how large the orchestra, or well-recorded, breathy strings would get, the A200 was able to hold the integrity of the delicate details in the music.

With my largest and most dynamic loudspeakers, “The Town Burns” was able to push the A200 to its limit where I felt the dynamics were not quite as extreme as they needed to be. It took ungodly volume levels to get there (peaks over 105dB at three meters) in an over-driven room, so I cannot feel bad about this miss. At all reasonable and high volumes, save the most extreme, the A200 truly shows what it means to be an extremely well-engineered piece.

Wrapping up the listening with an all-time favourite tune, Toto’s ‘Africa’ [Toto IV, Columbia], a song that was on the radio a lot when I first encountered Atma-Sphere as a company in 1982. Africa offers up a compelling mix of percussion and vocal harmonies that have made it a classic rock staple. The M-60’s brought out the best in this SACD recording with drums, xylophone and marimba’s anchoring syncopated rhythms that drive the song forward. Soaring vocals moved along across a wide and clear soundstage. The rains were indeed blessed. 

REVIEW: Naim ND555DAC and PS555 Power Supply

Yes, build quality at this level is superb, and of course, thousands of hours of research, testing, and prototyping went in the front door. But in the end, when you compare the finest DACs at this price point as a whole, they still outperform the DACs a click or two down. Finally, when you graduate to a player at this level, there is no more regret. You won’t find yourself sitting in the listening chair pondering, “if it only did a little more of this, or a little less of that.” Build quality, execution, ergonomics, and most of all, sound quality are all top. Another thought to ponder:  because Naim can build a product at this level makes their entry-level digital products equally compelling. There’s a deep pool of knowledge to swim in, so even if you can’t play at the top of the mountain, it’s still a good day wherever you can be. Naim makes a fantastic $3k player because they have the engineering chops to make a $40k player.

Naim digital players are at the top of the mountain when capturing music’s pace and timing. There is a correctness here that is achieved by precious few digital players, and when listening to acoustic instruments, everything in the mix feels as if it’s the proper size and has correct spatial relationships. Some players can feel overblown, yet with the ND555, you can hear the difference between an upright Steinway and a Grand. This level of musicality will have you looking at your turntable, wondering if you really need to fuss with vinyl anymore. It’s that good.
