I am looking for a new DAC and reading many reviews. 99% of my listening is to classical piano music in the CD format. A grand piano has a frequency range of 27.5 Hz to 4186 Hz. The Holo Audio Spring 3 has had very good reviews. But in looking at the frequency response how would this sound good rolling off in the mid-treble? Please see below. I post on ASR because I always learn something new from the direct comments. Thank you.
Stereophile Graph:
In NOS mode a gentle rolloff begins in the mid-treble with PCM data sampled at 44.1kHz, but starts a little higher in frequency with data at 96 and 192kHz (fig.6). The surprise, however, is that in DSD mode the Holo Spring's frequency response extends no higher with 192kHz-sampled PCM data than it does with 44.1kHz data. This can be seen in fig.7, which compares the responses with 192kHz PCM data in NOS, OS, and OS PCM modes with that in DSD mode. The last rolls off sharply above 19kHz.
