good afternoon mr. tanner,
after procastinating a few months, i've decided to take the plunge and just ordered the bcd-1.
for the last 8 years i've been living with an adcom 750. this is where my question comes in.
the adcom didn't have any digital out capabilities but it did have a coaxial input so another digital product could take advantage of the adcom's dac.
why doesn't bryston include a digital in facility on their bcd-1?
Welcome to Bryston ED,
It’s a very good question and one not generally understood.
In an ‘all in one’ CD Player the big advantage is that you know exactly what digital BitStream is coming off the Drive. Knowing this you can precisely synchronize the ‘DRIVE’ to the ‘DAC’ through a ‘MASTER CLOCK’. This reduces the JITTER to extremely low levels. (By the way we have found that the closer the DAC is to the CLOCK the better)
With an outboard DAC you do not know what digital BitStream your dealing with so you have to ‘RECLOCK’ and ‘RESAMPLE’ the digital input to allow the DAC to ‘Clock’ to the incoming signal. Again your trying to reduce Jitter to a very low level.
If we were to have a Digital Input on the Bryston CD Player we would have to use different circuitry to allow for the reclocking and resampling of the incoming bitstream.
Hope this helps.
James
