I can say this: I don't know.
It could be a couple of other things, too, like clocking issues (which could be related to power supply problems) or more likely, conversion from one digital format to another, as Tom has stated.
Yes , I'm sure you can have a very nice 2 ch system , especially considering they are H iii's. I have a pair of H i's in mine and enjoy them a lot (when the receiver works right , but that's a whole 'nother deal )
Exact pricing is an inexact art for Khorns of that era.
I consider $3K a fair price for both seller and buyer of late 70's Khorns, in excellent shape, stock AA XO's. It's up to you to determine if Crites upgrades are value added or not, as many people want STOCK, either for its own sake, or because the new owner doesn't trust someone else's mods and wants to do his own mods.
However the Khorns you are interested in are early 70's and don't have the very desirable AA's, or even the well respected Type A XO's. That is not a deal breaker, but I agree with others who have said for $3K I would expect the speakers to be in excellent shape and in the exact finish you have been looking for.
IMO the $3K is a fair market price if this is exactly what you want at this time, but if you are willing to be patient, deals at lower price points do come along on a regular basis. Are you willing to wait 3 months to save (for instance) $500? That's up to you.
Just now happened again. I clicked the cursor at the end of what I had typed and held down the backspace and it all went away, then I had to go quote you again.
When I highlighted the whole quote, then hit backspace, it would remove the quote but retain the person being quoted.....Hope that made sense.
Am I in trouble?
This is what I keep seeing: Hitting something directly with a hammer will impart more energy than if something is placed between the hammer and what's being impacted.
" In the typical system shown in FIG. 6 , the combined spring rate of k1 and k2 converts a portion of the kinetic energy created by the impact wrench into potential energy, thereby diminishing the kinetic energy transferred from the impact wrench to the fastener and reducing the amount of torque delivered to the fastener. "
^ A quote from the patent attachment
It seems that what the weight is meant to do is not bounce back and receiving and delivering the hits from the impact. Here is the US Patent for the socket. I haven't had time to read it all, but what I did read made it make sense.
