I'll stop here. Never mind. Enjoy your gear!
Hello -
Please don't go away mad. Let me offer a couple ideas first...
The LCD-4 are so amazingly resolving, you owe it to yourself (and to the headphones) to further explore upstream gear.
The best ways I know to do that are:
1) Go to a headphone meet or a CanJam. Bring your headphones. You can listen, for free, to different DACs and amps. Test your rig against others.
2) Go to a local equipment vendor, who will be happy to let you test their gear, probably with your own music.
3) Ask people on Head-Fi, who have been on the journey for sometimes years to find the best combination.
I have been lucky enough to participate in #1 and especially #3.
Yes, I did buy equipment without listening to it first. That's a risk. Several times, I failed.
But, I didn't buy the LCD-4 that way. It was too big a decision.
I had to hear them on my own equipment. This was after owning the LCD-X and XC. And hearing the LCD-3f at a meet.
Only a local headphone meet could enable that experience, for me.
So now, I'm a very satisfied LCD-4 owner. The level of musical detail, and enjoyment, is just amazing.
It was worth the work, at least for me. YMMV.
All the Best -
