Disagree - I think it’s preference. I greatly prefer my LCD 4 directly out of Dave vs V281, and I’ve always loved that amp with them. Same with my Auralic Taurus. Now I don’t doubt I might prefer a tube amp but it would be a preference thing. I find absolutely nothing lacking with the LCD 4 Dave direct. No decrease in soundstage, no decrease in bass quality, no strain, but much increased transparency. I think it’s truly a subjective thing by definition.
