Επανέρχομαι στο θέμα ανάγκης υπάρξης προενισχυτή σε digital front end συστήματα με κατάλληλα dac/pre. Παραθέτω τις αντίθετες απόψεις δύο reviewer για το ίδιο dac/pre που σε τεχνικό επίπεδο μπορεί να οδηγήσει τελικό (αντίσταση εξόδου 50ohm single-ended, 1ohm balanced):
Stereophile: "The differences in sound between the Debussy into a preamplifier and the Debussy directly driving a power amplifier will depend on the preamp's transparency, dynamic capabilities, and overall quality. Sending signals directly to my Musical Fidelity Titan amp from the Debussy or through my reference preamp, a darTZeel NHB-18NS, I heard minimal differences. Given the darTZeel's price of that's what you should expect. "
TAS: "That leaves me with one last strength and one real weakness to report. Let’s get the bad news out of the way first. Although the Debussy is fully equipped to directly drive an amplifier, I found it quite unimpressive in this capacity. As a linestage, the dCS sounds rather boring, with compressed dynamics and undifferentiated timbres. Only its vocal purity, quiet background, and solid imaging elevate it above mid-fi. I tried the Debussy in this mode with two different amps, with the same results. So, although being able to use the Debussy as a linestage would up the value quotient even further, I must instead recommend using this DAC as a DAC, sending its analog outputs through a good dedicated linestage. In my experience, that is the only way to hear what the Debussy can really do."
