Charles1dad, given a scenario where someone will ultimately select easy-load speakers and a tube amplifier to drive them, then it's quite possible the end result would be the same.
I understand your point.
The difference largely arises if someone might prefer a more difficult-to-drive loudspeaker. In this scenario, choosing an amp like the Leben CS600 (or one of many other tube amplifiers) would prove limiting, and might very well preclude the use of a speaker the shopper might have otherwise selected had the amplifier not already been purchased.
