100V on the tube plate, rather than 60V, for increased linearity and gain
Topological improvements that lower overall feedback and maintain performance
A new optimized layout with better signal flow and ergonomics
All-new attractive advanced-form USA-stamped custom chassis
Massively improved ventilation and lower operating temperatures
Like all Schiit products, Vali 3 is made in the USA. The vast majority of components, including chassis and PC boards, are made by US companies in the USA. Wall-wart transformers are made in China. All assembly, QA, and testing, including 100% instrumented test and 100% listening test, are done at Schiit’s Corpus Christi, Texas facility.

I will try to describe the DAC’s signature without the Atom AMP 2. For this test, I am pairing the DAC directly with my active reference monitors. Let’s start with the signature. Just like all the other Atoms, the Atom DAC 2 sounds transparent and uncolored. It is immensely clean and perfectly reflects the gear you pair it with, as-is, without any saturation. I am actually quite amazed at how JDS is able to achieve this level of performance with the old, reliable 9018K2M DAC from ESS. Of course, their precisely tuned trans-impedance stage utilizes six OPA1692 opamps, but still, it is one hell of an achievement and makes you question the must-have-latest-dac-chip race among Chinese manufacturers. JDS is once again showing off its expertise, a powerful reminder that implementation and execution reign supreme in audio design.

I’ve worshipped at the altar of David Lindley, singer-songwriter and master of all stringed instruments. His 1981 debut album with his band El Rayo-X (Asylum LP 5E-524) is spectacular on black disc, but the digital streaming version (16/44.1 FLAC Electra Asylum/Qobuz) has never grabbed me; I never listened all the way through until I listened with the ZMF Verité–Feliks Envy combo. With that, “Mercury Blues” came all the way alive, and my feet weren’t tapping the floor; they were pounding it. My head was bouncing, and I was cruising on down the road. Plus! I can’t mention this album of full-tilt rhythms without a shout-out declaring Ian Wallace, once a member of King Crimson, the alpha dog of funky drummers. On “Mercury Blues,” Wallace was so good and having so much fun, he made me laugh out loud in the middle of a song.

After parking my new Mercury, I entered a seaside tango bar, and there she was: the beautiful Argentinian chanteuse Susana Natividad Rinaldi, sounding like Edith Piaf and looking like a singer in a David Lynch film. The seductive tones of Rinaldi’s voice forced me to adore her. The dense reverb that framed her voice and made the band’s instruments vibrant did not fog the recording’s transparency or soften its focus. The album that supplied that vision is called A Homero Manzi (16/44.1 FLAC RP Music/Qobuz), and I swear that every instrument and player in her small orchestra was delineated clearly enough to watch and follow what they were doing on the stage.

As for the headphone output itself, SMSL stayed vague but announced conservative numbers. With a 32 ohm Load, the SMSL AO300 harmonic distortion reaches 0.003 while maintaining an average signal-to-noise ratio (107dB). A league below the DO400 and even DO200, but the brand top that with the all-new Infineon MA5332MS, which makes the AO300 very interesting.

Why? Because this Class D chip makes the AO300 one of the most powerful speaker amplifiers available in this category, outputting no less than 165W per channel at 4 ohm, and 85W per channel at 8 ohm. Numbers that make the AO300 battling with mid-range amps like the Teac TN-303 – that shares a lot of common traits, but at 2-3 times the price.

You might feel that the top markings, such as the MQA badge, Hi-Res Audio markings, or the block diagram, are a bit unnecessary. It would have been better if they had followed a similar approach to the flagship M30 unit, which displays small areas of the circuit board, but this one is all enclosed.

The topic of design is always subjective, but I doubt anyone would find a flaw in EH3’s build quality. The device is exceptionally well-built, featuring a glass front and a complete aluminium wrap-around chassis. It feels like a rock-solid device from top to bottom, and the volume control is particularly impressive with good rigidity and satisfying clicks. All of the ports, inputs, and outputs are also nicely built, leaving me with zero complaints.

The Bryston will never be confused with a tube amplifier, but texture and tone through the HD800?

Hell hath frozen over. 

The Bryston BHA-1 blurs that line rather significantly offering up a cleaner sounding and more detailed presentation than any of the tube amplifiers in my collection, but with a warmer tonal balance than I would have expected.
