Rebote delay at max delay times

[crane]

Hi everyone.
I built a rebote delay about a year ago and while it sounded great at short delay times and a small amount of repeats it turned a little bit to a bit crusher when both of these controls were maxed out. I couldn't bare with it and gave it away to a friend. The other "bug" for it was cutting delay trails when pedal was turned off. Well I know - this is ok - most modern delays have an option to choose trails/ no trails but the most annoying thing was if you turn it off and the on again - you can hear trails from previous use. I managed to fix that easily by changing the circuit a little bit (it had to be changed from true bypass to buffered bypass and the switching mutes delay input) - haven't read that anyone has done this so may be some of you will find it interesting (I think that echo base has a similar principle).
Sorry for such a long prologue. Here comes my main question - I know that most of manufactured digital effects come with a compandor/expandor before and after ADC/DAC processes. Does anyone know how would introducing for example as SA571 into rebote circuit work? I know that PT80 has it. Unfortunatly I cannot find any clips with max delay time and many repeats.
Or may I had a faulty build and rebote is not supposed to distort?

The Yerasov DM-5 also has a compander section (and dual PTs for extra time).
