I listened to the DAC (burned in for at least 400 hours) as well as the Amp section (burned in for at least 1200 hours) and I think the DAC holds the amp section back.
Oh, it's definitely quite listenable and, sure, it's (way) better than the TBAAM and even, from memory, betters the Total Bithead (which also suffered from a slight bit of hiss as a DAC, but put out a better signal level than the Predator DAC does). But, compared to the Predator Amp being fed from the ibasso D1 DAC with LT6241 opamp in it, the Predator DAC is a disappointment for me
.
It's not that it is in any way bad. In fact I see it as a quite functional USB DAC, with good sound...but exactly that - good. For me the D1 is very very good - I could listen to it feeding the Predator feeding the Livewires for many many hours: with the Predator DAC it's like listening to something that's fine for background but lacks some of the punch, dynamics and detail that I want when listening to music for pleasure/enjoyment. (Which means that although it has those features, they are a little less present than when I'm running the D1 through the Predator - and I am simply a PITB when I know I can choose a better, even if it's only slightly better, sound
).
I find the Predator DAC to provide a sound that is a bit veiled, a bit abrasive and actually draws back from the delightful sound the amp alone can produce. It's just not as rounded as the D1. Less atmospherics, a little bit tinnier with the top end. It's like the converse of the D1, where it's the amp that draws back the excellent resolution of the DAC. Predator DAC vocals are pleasant, bass is a bit muddier/less defined (which reduces the effect of ultra-resolution and detail that the amp section by itself produces so, for some, this may be considered a good thing, slightly more 'integrated' sound, more musical?, than the amp section by itself). But the high end is definitely not as tonally accurate as the amp alone is (even though the amp alone has this as a slightly weaker area to begin with - but in the DAC it's, for me, patently obvious
). The Predator DAC also slightly lacks the bass amount and resolution of the D1 and Pico DACs.
The Predator DAC also puts out a smaller signal than the external line-in levels normally are, meaning that when running the DAC/Amp combo you are pushing the volume control and/or the Gain level more than with the Predator amp being fed from an external DAC.
