Kaldas Research - RR1 Conquest was the biggest show surprise for me. Sounded great with the Mjolnir amp. I was expecting nothing and immediately was astonished. Great electrostat sound for not a lot of money. Prefer it over Stax 009, the RR1 has much deeper bass. I was instructed they go down to 40 hz. Hair dry, but it's so fast it had a pleasantly fiery disposition to it. Meze - Empyrean is probably the smoothest and most refined headphone I've heard. There is literally nothing offensive. It's so inoffensive I'd dare say it's in the vicinity of polite perfection. Balanced and super comfortable. Impeccable build quality. MrSpeakers - I brought my own pair of Ether 2's. Not much to say here, I love these headphones, even though I do EQ a bit of treble in. Audeze - Going from an LCD-4z to the LCD-GX was a buzzkill. A better comparison would've been the LCD-GX against an LCD-2, it had that kind of grain. Not engaging. Schiit - Listening to Ragnarok 2 again was one of my main objectives. I was surprised to learn I liked them better with my Ether 2's than with the LCD-4z's. Rag 2 made the 4z's a bit shouty, but paired great with the E2's. Interestingly, the DAC makes a huge difference with Rag 2 + Ether 2. I really like how the Modi Multibit card sounds with this pairing but when you substitute Yggdrasil you get some sharp treble that's unpleasant. My friend echoed this remark. QUAD - Despite being a tube amp, PA-ONE+ actually sounded great on planar headphones. My Ether 2 paired great.
