Best speakers for $300/pr


I have a friend who has owned KLH 6’s for lo these many years.
He wants to upgrade.  He’s getting a new Marantz receiver and doesn’t want to spend more than about $300 for his speakers.  Can he get anything decent at that price level?

Seems like the KLH 6's were $250-$300 when new. How much is that in today's dollars? IMHO, $300 will get something different for sure, but not likely an upgrade. Since he has had them that long, are they just sitting on the floor or sitting on a short tilted stand? Is there a problem with them that needs repair?

I'd make a bid on these Silverline Minuets that are far more than decent...

Or if he prefers to buy new, these Aperions are very decent and a good value as they're on sale and sold direct...

Maybe have @grannyring make him some Dueland speaker cables and interconnects if he needs decent wires too. 

Best of luck. 
The Ascend Acoustics CBM-170 is <$350 shipped and is pretty much unmatched for the price.
