One of the more discernable failures of other competing DACs is their inability to faithfully recreate the space, and the subtleties of the physical placements and interrelationships, of the instruments spanning the soundstage. So many of even the most well-regarded offerings deliver a decidedly more dimensionally flattened instrumental image and limit the depth and breadth of their layering, presenting something that resembles more of a cardboard cutout propped up in front of you rather than offering the sense of the more real spherical wave launch and presence you so lucidly experience when hearing live instruments played in a real space. This near-consistent weakness of many DACs has been one of the most crucial factors fueling my ongoing resistance to digital music playback over the years.

I’m really impressed with the DX7 Pro, both as a DAC and headphone amplifier. It certainly scores on sonics and is up there with other high-quality DACs currently available. It has loads of facilities and can accept inputs from a wide range of sources, including Bluetooth, USB, coaxial and optical. With its fully balanced circuitry, it will also be great for professional users while the ability to support balanced dynamic headphones is a real plu

It might be the most basic digital device in SPL’s ‘Professional Fidelity’ range of consumer products, but the Diamond DAC is both superb-sounding and something of a high-end bargain. By focusing on essential flexibility only – no fiddly filters! – the company has come up with a design that’s both easy to use and capable of excellent performance across a wide sweep of musical genres.

With the original DirectStream’s volume control set to its maximum of “100” and the Parasound monoblocks set to high sensitivity driving the KEF LS50s, I could hear no hiss with my ear pressed against a tweeter. (For my auditioning, I used the Parasounds set to their lower sensitivity and the PS Audio’s volume set to “76,” ie, 12dB below the maximum.) Repeating the exercise with the MK2, some noise was audible, but I couldn’t hear it if I moved more than a few inches away from the speaker. The level of this noise didn’t change if I lifted the USB ground via a Menu setting, and it wasn’t affected by the setting of the MK2’s volume control. It might be best, then, to avoid using the built-in volume control in a system with high-sensitivity speakers, like the Klipsch La Scala Alex Halberstadt reviewed in April 2023, where the music volume may need to be turned down to levels at which this noise becomes troublesome.
