They will not work on a grey market product period. Thats the difference between No Warranty vs Grey Market. This is common practice which Im sure almost all distributors of any brand will tell you.
The Seller amended his description many hours later at night. This was posted in the morning. There was no need for me to further communicate with him all that time later. After his initial email to me I told him I wasnt interested once the truth about the origin of the amp came out. Im not buying any product that will be refused service by the manufacturer. Im a gambler by nature but not when $10,000 - 15,000 is involved.
No further reason to discuss this topic as its no longer listed and many dont get the ramifications of buying a grey market product going by their replies.
