Hi everyone, What would be the best upgrade to AKG Q 701s? I want a good all-rounder, something that can sound great with all genres. I was thinking of Beyerdynamic T1 but some say it's not much of an upgrade over Q701, despite the massive price difference. I don't want neither very analytical nor very warm. I want neutral and musical headphones. I have a Meridian Explorer (revised version). It can drive the Q 701s fine. I'm not sure how well it can drive 300 or 600 ohm headphones.Tyll says 300 ohms are great with Explorer.
