Do ClassDAudio Amps Have Proper Decay Of Notes?
As I’ve mentioned hear and on other threads, to me Class-D is still in it’s infancy with problems of having class-d switching noise filter effecting the phase in the audio band right down to 5khz, Technics with their SE-R1 have raised this switching noise filter more than double the frequency with special much faster semiconductors with far less effects into the audio band, Absolute Sounds and Stereophile seamed to enjoy this amp very much.
"Conclusion: Absolute Sounds:
The Technics R1 is exciting on many levels. On a technical level, it points the way to a future where digital signal paths are much simpler and more direct—and therefore more like analog—and solid-state overcomes the last hurdle separating it from tube-like holography. On a sonic level, Technics has managed to create a system that does virtually everything right, including self-effacement in service of the music. Value is another cause for excitement. True, the price point of the R1 system puts it out of range for audio acolytes. However, this system will—and in my listening room did—satisfy some of the most finicky, hard-core audiophiles, used to listening to far more expensive gear. The Technics value proposition remains strong, even in this price range.
Finally, the R1 system is exciting in that it heralds the return of Technics, a brand that once paved the way for new audiophiles to enter the fold, and for numerous technical advancements that eventually became standard practice. Today, with the R1 system and lower-cost variants that incorporate much of its technology, the company is serving the same twin roles. Technics is back, and its return is most welcome."
"Conclusion: Stereophile.
Although the SE-R1’s huge twin output meters and beautiful anodized-aluminum finish were visually distracting, the marketing of a class-D amplifier as a separate high-end component was important. This amplifier delivered some of the best reproduced sound at CES 2017. I persuaded Bill Voss to rip the contents of my copy of Rutter’s Requiem to his media server’s solid-state drive. The broad and deep soundstage, imaging, upper midrange detail, and bass extension were thrilling during the system’s rendition of "Lord, make me an instrument of thy peace" and "Pie Jesu." I appreciated the work done by the Technics staff to prepare their exhibit suite with recessed sound-absorbing panels. I left wanting to hear more.
