Just wanted to give a heads up to those that were waiting on backorder also for their samples...

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?

AD1865 · 19th November 2003, 01:02 AM

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?
