Re: Sidestep for PLX
I guess I should have put the phrase "almost never" in big, blinking red letters. Why? Because there are always exceptions.
We ran Crest Pro *001 amps for 20 years. The amps that replaced them are higher output, lighter, smaller, smarter and can currently be repaired... none of which can be said of our former Crest inventory. Not bashing Crest, we they did very well for us for a long time. But if we had decided to replace them 10 years ago we'd have wasted a big chunk of that investment.
I agree, however, that including the costs of repairs, preventive maintenance and eventual replacement in the total costs of ownership should be done so that those expenses can be factored into the "cost of services delivered" for cost accounting purposes. This is one of the things about "costing" that I didn't know or understand when I started my "van-load of PA" company 30+ years ago... and it was a lesson I learned only after I realized the severity of this ignorance.
After 3+ decades in this little psycho-acoustic endeavor, I can say the biggest challenges are not in making sound, but making a profit making sound.
