I think it is hard to quantify the amount of better(I use the word loosely) sound. I could easily tell there was punchier, more pronounced(?) bass at any sound level , well any that was worth listening to and the highs were also that much crsiper, airy, (insert your own favorite audiophile word here). Was it a 10, 20, 30% increase in sound quality? I don't know. Is it worth the added expense for the A1400? To me it is. Can I afford the A1400? No \:\( . Am I going to feel I am lacking anything when I finally get into the new house and fire up the M80s, 3808 and the rest of the system, not really. The system still plays incredibly detailed and low and I feel I would have to spend BIG bucks to improve upon it significantly for me to justify the expense.

As I have said I am looking for that outboard amp but it has to WOW me like the A1400 did and I am not so sure the cheaper ones will.
