For sure Wadia will not service a modded unit.
Heck, they can't even service there own units in a proper manner.
I have owned three Wadias' over the years & have had a problem with every one of them. Never again. I don't care who buys or bought them.
I have moved on to the Playback Designs MPS-5 & could not be happier. Sonically much better,,, service & upgrades are top rate. Highly recommended, period.
BTW, I have a 781i that I have been trying to get repaired since September with no results, calls unanswered, emails unanswered. People need to know what they are dealing with when they want to purchase a so called high end product.
I have also know of a few other horror stories.
Maybe if the Shareholders see a few of these threads they will decide to do something about their companies problems.
Move along, nothing to see here.
Good Luck
