NuForce DDA-100 Integrated Amplifier Review

Browsing through underappreciated singer songwriter Martin Sexton’s catalog, I pulled up his breakthrough album, The American. Having heard this album on countless systems, I was quite taken aback at how the DDA-100 unraveled some new layers in this recording. It really did feel like several layers were peeled away from the sound as compared to other DACs and analog amplifiers.

The 96 Khz, 24 bit download of the terrific new album by Tom Jones, Spirit In The Room, sounded spacious, clean, and vibrant. The organic, warm production suits the material perfectly, and Jones’ voice is impressively realistic. He covers such songwriting giants as Richard Thompson, Leonard Cohen, and Paul McCartney, getting to the heart of each song. The DDA-100 really hits home with the emotional impact.

The DDA-100 was excellent on naturally recorded acoustic music as well. On a live recording by the Wayne Shorter Quartet from Paris last month, the interplay between the incredible band was panoramic. Shorter’s horn was appropriately brassy, on occasion, delicate, and soulful. The support from long-time band mates Danilo Perez on piano, John Pattitucci on bass, and Brian Blade on drums, came through as amazingly sympathetic.

Where does the DDA-2 fall short? Literally the only place I was left wanting, just a tiny bit sonically, is in bass impact. I felt the lower frequencies lacked the full weight I've heard from other amplifiers. However, the articulation and accuracy were simply superb.  Of course, matched with different speakers, results may be different.

My only other nitpicks are ergonomic, and quite frankly, minor. I do wish the DDA-100 decoded 192 Khz files. Also a sample rate indicator would be nice, which is always on my wish list, but rare to find at this price point. Other than that, NuForce has simply hit it out of the park with the DDA-100 in terms of sound quality, ease of use, and price.

After spending almost two months with the NuForce DDA-100 direct digital amplifier I can honestly say I feel it is a breakthrough product, especially considering the $550 price tag. The DDA-100 eliminates the need for an outboard DAC, and keeps the signal path for digital source components at a minimum. The fact that I heard more of the original source material's texture, ambience, and transparency through the DDA-100 than other, more costly, digital components is proof in the pudding.

As mentioned above, the only real concern I had was a certain lightness of presentation in the bass area, but this may be a speaker/amp thing.  For instance, I can say with certainty the DDA-100 would be a superb match with the wonderful Boston Acoustic M25 monitors I reviewed. I am even hoping NuForce builds on the unqualified success of the DDA-100 with a model with more power. That is how much I believe NuForce has nailed it.

I think most astute listeners would be surprised at the DDA-100's level of performance. I personally think it outperforms many far more expensive amplifiers in several key areas. Of course, a reminder is needed here -- if one has analog sources, or inefficient speakers, the DDA-100 won’t fit the bill. For those with only digital sources, it gets my highest recommendation.
