Hey James,
There is a new DAC chip from AKM. The number of the DAC chip is 4497 and the specifications appear to be better than 4490 chip, specifications listed below:
DAC 4497
- Maximum Sampling Frequency, Bit rate: PCM 768kHz/32-bit, DSD 22.4MHz
- SNR:128/131dB
- THD+N: -116dB
- Sound Color Digital Filter: 6 types
DAC 4490
- Maximum Sampling Frequency, Bit rate: PCM768kHz/32-bit, DSD128(5.6MHz)
- SNR: 120/123dB
- THD+N: -101dB
- Sound Color Digital Filter: 5 types
And now the question is if Bryston will test this new DAC versus the existing DAC in the BDA-3?
