Thank you, Mike!
I've already bought the TA-10. I tried him on the Quads and I'm more than impressed. I've let it burn in for a few hours before I judge it's musical qualities, but power-wise this little baby has no problem driving the Quads..With the volume at 9 o'clock it's loud enough for when I enjoy my evening coffee and at 12 o'clock I get enough volume to let the neighbours know I'm around. Still can't believe it..
