That is not true, Krell offered to the original owner their new completely updated top processor for 2.000 US$ + the old one, it was 3.000 for later owners, a lot cheaper than upgrading the TAG, I only got 55% of what I paid for mine, and that was before the news...
Processors, at least new, should be bought from authorized dealers, there is much upgrading going on, I wouldn't risk, not to mention the voltage issues...
