30 Day Status Report on the $50 DAC
Today marks one month of “fairly regular usage” so, according to the manual, the DAC has burned-in and reached optimal levels of performance. Throughout the month , I left the analog outputs of the CD/DVD player connected so that I could switch back and forth between the internal DAC (24bit/96 audio DAC according to Njörðr Nóatún) and the 20bit Entech 203.2.
There was an immediate improvement in CD sound quality with the Entech. The difference became much more pronounced after the initial 24 hour burn-in, with gradual and continuing improvement as time passed. In particular, the highs showed the most improvement over the period. Initially, they were a bit metallic, almost brassy. Over the month, they opened up, bringing additional depth to the sound stage. The mids were very good from the start, but have opened up as well. A little change in bass is noted, becoming more musical over time.
I set out to really listen today with a selection of favorite music: Robert Randolph and the Family Band’s Live at the Wetlands; Madreblu’s Necessità; Tutto Fellini (Nino Rota’s film soundtracks); and Nucleus’s Elastic Rock. On every single track, the Entech performed far, far better than the internal DAC.
One of the most striking improvements was noted on Madreblu’s album. With the external DAC Raffaella Destefano’s silky vocals purr from the speakers. Live at the Wetlands charges out into the room with all the energy and image of the live performance. Nino Rota’s work for Fellini has always been a self-indulgence and, with the DAC there is so much more depth, clarity and separation of the individual instruments that I am receiving threats regarding its frequency of play. Quite possibly my favorite album, Nucleus’s Elastic Rock has been a revelation. I was able to purchase a limited edition (2500) re-mastered CD of this album. I have a vinyl collection of Nucleus going back to 1970, which includes an import copy of Elastic Rock. For the first time on my system, I now have a CD that actually sounds as good as ( and maybe, just maybe a little better than) the vinyl.
There is simply no real comparison between the sound quality produced with the 20-bit Entech and that produced with the 24-bit internal DAC of the Panasonic. When I switch directly between the two, there is a loss of at least 60% of the bass, highs, clarity and imaging when the internal DAC is used. I’d have to spend lot more than $50 buying a quality dedicated CD player to match what the Entech has done for my system.
