500+ Head-Fier
I normally listen to my DAVE with the Focal Utopia at volume settings between -20dB to -35dB depending on the music material. I had the pleasure of listening to the LCD4 with my DAVE at one of my local Head-Fi meets and I found myself setting the DAVE at -10dB to -20dB. However, I've found at these meets (and at my local stereo dealer) that I generally listen to music at 5-15dB quieter than most people. In fact, I think I met somebody at the local Head-Fi meet who clearly listens to music at 20dB louder than I do. Since DAVE clips at a volume setting of +4dB, I guess whether DAVE is loud enough for LCD4 would depend on your listening level. Everything was plugged into the headphone jack.
That said, at the Head-Fi meets, even with more efficient headphones, it was clear that some people just prefer having a headphone amp instead of direct out through DAVE. I never notice the issue being DAVE can't drive those headphones. I think different people just prefer different sound signatures (or distortions if I were less polite or more controversial). Prior to DAVE, I had the Benchmark DAC1 amp/DAC so I'd say the headphone amplification signatures are very similar and very neutral even though obviously the DAC in DAVE is in a completely different league.
