Well Jim and I are at 100% opposite positions on this point.

Bonding from equipment to equipment is a series circuit in which the 
voltage divides across each value of R.  Thus none of the equipment will 
be at zero potential.

By using a bond conductor from each piece of equipment to a common 
point, this provides a star system which is endorsed by most audio and 
system design specialists.   It provides the lowest resistance as all 
conductive paths are parallel.
