T+A Elektroakustik DAC 8 DSD High End D/A Converter Review
March 21, 2019 § Leave a comment
“Much like any top DAC these days, digital filters offer the listener a customized sound. Want a softer, gentler approach? Done. Want an etched, lean performance? You got it. I spent a few days reading the manual and pressing buttons. I settled on one filter and left it for the duration of the review. I did the same when reviewing the Mytek Manhattan DAC II; the MQA setting, which the T+A does not offer (an MQA software update is in the works). I used Qobuz, primarily, as a streaming service via Roon on my Antipodes CORE Music Server. With Qobuz, there is no MQA support, but some seriously amazing hi res recordings available from the ever growing Qobuz catalogue. You won’t miss it.
Here we get a choice of four oversampling filters, used only for PCM audio (the 8 plays DSD, too, up to 512). There are two Finite Impulse Response filters and two Bezier interpolations. My choice was the ‘BEZ 1’ (blue LED), which is said to produce results ‘similar to an analogue system’. All four filters offered refined, superior sound, with enough variation to satiate the most nit picking listener. ‘A Bézier curve is a parametric curve that uses the Bernstein polynomials as a basis.’ Deep MIT dive here. To me, ‘BEZ 1’ sounded as detailed as the three other filters but with an even more pleasing musicality. ”
