Well I had the pleasure of cutting into an Ethos last night (for the sake quality control). Since I wasn't using them and Quentin sent me a recone to replace it. We both wondered how the overall parts looked after 5k watt burps for 6 months. The results were outstanding. Coils still looks new, leads were in excellent condition and the spiders showed no signs of breaking down, burning, fatigue, or otherwise. Snapped a few pics for Quentin. You can say I'm pleased with what I saw. Keep it up Quentin. You have a great driver here.
