Any more news about possible HE-500 quality control issues?
Finally received my replacement HE-500 (first unit had L/R imbalance). Tested the drivers on my Fluke meter and got 44.8ohm on one side and 45.1ohm on the other. Replacement took 3 weeks to arrive after they received the bad set, so not the most responsive customer service.
But the sound quality is fantastic out of the box, currently doing some burn-in. Unlike some I do notice an improvement in SQ for orthos after 100+ hours of run-in. I'm expecting the bass to be a little tighter/better controlled and a slight edge smoothed out from the treble.
These are more power hungry than I had expected, but my Pioneer SX-D7000 is having no problem driving them.
After reading this thread I measured my HE500 and found L=24ohm / R=35ohm
Thank you Murray for doing that math. This is why I was curious of Argybargy’s measurements, he seemed immediately aware of a problem, but this imbalance never jumped out at me. On the other hand, I’ve never really warmed up to these HE500’s either. Maybe they are capable of much more had the drivers been better matched.
Out of curiosity I measured all my other speakers in the house, Klipsch, Meadowlark, Celestion, AKG K340 & LCD-2’s and the worst discrepancy I found was only 0.1 Ohm. This makes me wonder if these HE500’s shouldn't be better matched at this price point?
Subscribed. I was thinking about "upgrading" to the HE-500's after returning my HE-400's. After looking inside the HE-400's I get a very queasy feeling about everything about this company. I am, however, hoping that the HE-500's are better with respect to internal build quality and overall QC. Your post gives me pause...
What are the quality problems?
damn, I was wanting to get a pair of these. I still think I'm going to get a pair. If I dont notice any difference in volumes between the 2 driveers, should I still get a multimeter to measure them for any differences?
