iBasso DC04. This bigger sibling of the DC03 is about as similar sounding in every manner – and they both should because they are identical inside. Sparkly, resolving, transparent and vibrant. Now with HUGE driving power of 4 Vrms from the 4.4 Pentaconn port. It makes driving Magnetic Planars like a walk in the park, not even touching 60/100 even on the lowest volume recordings. With balanced circuit, the DC03 goodness now have an improvement with the soundstage being a bit more spacious and wider, even better spaced layers with great imaging (not that DC03 was lacking, but the improvements do help). As how I already noted for DC03, all these thanks for iBasso masterstroke of keeping the Firmware updated and thus keeping these two DC siblings highly relevant in present day contest. I am impressed and I liking what I am hearing from both of them. Oh yes, DC04 is the most POWERFUL dongle tested so far with that 4 Vrms.
DC04 vs Ovidius B1:
- Ovidius B1 exhibited slightly more audible micro details.
- Ovidius B1 has slightly thicker bodied timbre and bass decays
- DC04 has more pronounced treble sparkle
- DC04 has slightly spaced back Mids, B1 a bit more forward
OVERALL RATING: 98/100
Recommended Pairing: Anything up to 250Ω or above 94db sensitivity.
