You did not say what modes are being tested on the linked
repeaters. My guess is that one or more of the repeaters are
distorting the signal with the pre and deemphasis associated with
voice repeaters. You also might check to be sure that the repeaters
do not have tone notching enabled. Lastly, the signal levels should
never drive the repeater audio sections into clipping.

I participate in a digi net that works VHF on a linked repeater
system with four repeaters. They mostly do FLMsg traffic, but
I've tried to send FLAmp traffic on it.
It just doesn't seem to work as well as it does on HF (which, of
course, is simplex). For a nice, clean signal environment it drops
a lot of blocks. Some operators eventually get it completed when
I retransmit the missing blocks, and others don't.
We've done everything we can to cope with the repeater
environment. We've enable TX/RX interval so the repeaters don't
time out, use a 2.5 second pre-signal tone on the RSID, and have
the SignaLink delay set to about 60%.
FLMsg works pretty well (although sometimes parts of it get
scrambled), but FLAmp just doesn't seem to. Is there something
about the way FLAmp does it's error checking that isn't compatible
with a linked repeater environment? Has anyone else ever tried it
over linked repeaters?
