Blew them up? Curious how that happened. I’ve listened to Focal stereo speakers but not the HPs. Presume the the sound signature is similar, which makes me think of the Fostex line, I use the TH900s. IMO, they are slightly warm with a “v” graph dip. Aka, slightly reduced mids compared to hi/lows. Using tubes gives them a bump in the mids and reduces sound pressure at the hi/lows, balancing things out. They have a v. large soundstage with excellent isolation. But also very intimate (are these guys playing in my head???) Although the TH900s are a $ grand, the point I’m getting to is the other Fostex models: mass drop TH-00s (I think) and their current TH610. They are more or less like the TH900s, just a bit less refined, and therefore around the $500 price point. In any case, the Fostex cans are musical and play nice with most genres of music and diff amps.
