My concern is that thousands try a $20 - 100 cheaply built (corners cut) digital and only be mildly impressed. Combined with a closed minded attitude they easily turn back to whatever technology they've been happy with, having never given this still developing technology a fair shake.IMO a $500 Clari-T compares very well with $2000 + SETs, but you'll trade 4 hour battery runs for the romanace of tubes. Even 100 wpc + solid state amps don't provide the same bass control of a small digital for some speakers.
In an age of instant gratification people just aren't willing to wait for technology to mature or hunt for synergistic pairings, especially when it comes to electronics.
