Romy,
I'm not sure how "transparent" you find the Lavry etc AD/DAs, but since you have them, it might not be difficult to throw in an adjustable digital delay; eg these chips from TI

There are evaluation boards with differing features (on board DA etc which you wont need) available too; if you can provide I2S interfacing and live with fixed delay in units of 256 samples, then the TPA5052 chip is very easy to use; I2S in, I2S out and 5 bit delay selection input. If the I2S is an issue, I'm sure there are interface ICs that will do the trick.
It extracts a clock signal from the input data so hopefully won't introduce too much jitter.
Cheers
