Short answer: the Sivga P2-Pro. Both are rated 3.3/5 for sound quality (#292 and #291 of 481 over-ear headphones), and the Sivga P2-Pro costs $449 against $499.99 for the Dan Clark Audio Aeon RT Closed, with sound quality a draw, the lower price decides it.
Why pick the Dan Clark Audio Aeon RT Closed: A light 0.7 lbs (328 g) closed-back planar with a neutral bass level (within 0.1 dB of target) and a Harman score of 66, sold by Dan Clark Audio for much less than its flagships. Watch for: Treble sits about 2.9 dB below target, so it can sound a little dull next to brighter headphones, and it measures behind the older Dan Clark Audio Aeon Flow Closed (79).
What the Sivga P2-Pro does well: A broadly balanced tuning with a preference score of 66 against the Harman target. The tradeoff: Treble about 3 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
Buy the Sivga P2-Pro. Both are rated the same for sound quality, and it costs $50.99 less than the Dan Clark Audio Aeon RT Closed.
