Scott Dorsey... whoa!

It appears you are doing the redefining here. There has always been
some wiggle room when using the term bias-compatible... at least since
before I was shaving.

No two formulations are exactly the same, and they don't have to be.
It is not a precise point, but rather a range in which the industry
recognized bias compatible formulations all fall within. In fact it
was quite common among many engineers to bias up for 456 and use tapes
such as 3M 226 and BASF SM911 without rebiasing. Using SM468 in this
way, as Frank Zappa did, resulted in a sound that many people
preferred over the factory recommended bias. On the other hand some
such as Tom Scholz tweaked the bias so precisely with his beloved 3M
226 that no mere mortal could possibly hope to duplicate the

The subject of bias can hardly be addressed so universally as to fit
all machines, all styles of music and all personal preferences of all
engineers, producers and recording artists.

Perhaps this unattainable bias compatibility you speak of is fun to
kick around in academia, but in the real world of recording that's
just not how it is, or ever was.

I had hoped you would thoughtfully reconsider your phraseology in the
RMGI review concerning the use of SM911. Although it wasn't the
central point of the review, as it stands those statements are simply
inaccurate and perplexing.

So far all I've seen since my last post is a lot of dodging and
confusing the issue... splitting hairs indeed.

There are few reviews or articles that don't err on some point of
fact. None of us get it right all of the time. How one reacts to
reasonable criticism is where one's integrity and authority stands or
falls in my book.

I feel you are digging quite a hole for yourself here. Lets not
rewrite recording history here just to cover a few slips in a magazine
article. It's not that big a deal.
