+1 @soix on Audeze. For what you de@mlapenta you might be really happy spending much less than the amount you specified. The Audeze LCD-2F costs significantly less than the LCD-3, but it might suit your sonic tastes better if you like it a bit on the warmer side with a softer top. Allocate $300-400 on a quality aftermarket cable and the rest towards a headphone amp if you do not have one that will drive the Audeze to perform its best. The LCD-4 is also worth listening to, but you’ll have to find it used to reach your price.
Recommendation for Headphones
My current rig is a Lumin U1 mini feeding a Intona isolation unit feeding a Chord Qutest DAC feeding a Primaluna evo300 integrated amp with tube upgrades.
I use Goldenear Triton 1r speakers.
What would be a good headphone for this setup. Would like to keep it under 2500 if possible. Thanks Much
