Fix or replace Accuphase DC 91 DAC?

One channel coming out of the Accuphase is suddenly badly distorted. With a qualified audio guy, we did everything possible to narrow the problem down to the DAC.

I do love the Accuphase and will probably fix it but before I do, I thought I'd post to hear any opinions on options such as replacing it.

I am using it with a Shindo preamp and CJ Premier 140 amp.

Cost for repair would be $1500 plus shipping.

Thank you in advance
