Visual Comparison: Fidue A66 and Fidue A65
The (brown) Fidue A66 is the follow-up model to the revered (copper coloured) A65. Both sport single DDs drivers although with a completely different tuning: The A65 has a V-shaped frequency response and the A66 a more flat one. I purchased the A65 and the A66 is a warranty replacement for a faulty A65 from the Penon Audio Store. A full review of the A66 will follow.
