Default I have tryed AD1896

IMHO, The AD1896 sounds smooth but no bass strength, and with no sensation, becaue the data is completly changed! It's garbage.So I don't think the SRC4192/3 can give us an better sound than without it, although its spec is very good.

I have some boards for AD1896/AD1853 that would work, but there is some kind of clicking in the left channel. Very annoying. I am wondering if is because I used very early stock AD1896, I know there have been some problems with those.

My DAC DIR1703+AD1896+AD1852 runs well,but the sound is
very "atony" and lack bass.Check the circuit diagram if some sets
wrong.

Do you use slave-mode output?

Default I didn't use slave-mode output

I only use 96KHz sample rate,the slave mode is hard to
use,and the THD of AD1853/2 in 192KHz is worse.

Make sure that the /RESET timing is being correctly met. /RESET must be held low while the rest of the AD1896 powers up, or problems such as clicking may occur.

I haven't found the AD1896 to make any change in tonal balance. In my setup, the strength and general character of the bass is the same as without the AD1896.

Which D/A do you use? My DAC with AD1852 can easily been
heard that the bass have no wallop. Although I use AD811 as
buffer.

I'll have to check ~RESET out Brian--thanks. First time anyone had heard of a similar problem!

I use a global reset, for DIR, ASRC, and DAC (from a reset generator). The PSU is stabilized by that point, but since DIR and ASRC are simultaneously reset the input clocks are not active when ~RESET goes high. Do you really think this could be the reason?
