Are you sure you must have this particular frequency? (The answer is that you must order a special made crystal)

You are better off getting a higher frequency crystal and driving a counter with it.

I've worked on gear that uses about 400kHz and they use this method.

If you really need a 44.1k crystal it will be VERY expensive.
I suggest going for a freq range that is commonly made, such as for HF radio at about 4.41MHz

Look here for some excellent theory (and they are a good supplier too.)

Make sure you read about aging.

If you want an over the top audiophile solution use a TCXO.

Get an 11.2896Mhz crystal from an old Philips CD Player and divide by 256 (or similar from another CDP with appropriate division)
