I went to the Bristol Hifi Show on Friday, mostly focusing on headphones. This is not a collection of reviews but a few notes about the more interesting higher end headphones on the market.
Measurements and experiments carried out on a more spacious AK4490 test board
- Better understanding on improving AK4490 performance
- Encouraging results regarding Wee DAC performance goals
- Massive boost of 10-15 dB in THD+N at low frequencies
- THD+N at 1 kHz measured beyond -110 dB on test board
- Does not mean Wee DAC will achieve these though
- Modifications will increase BOM cost so need to consider the benefits and find a good compromise
