I have actually compared these 2 speakers just not back to back (different dealers, different gear). I thought the 20T's provided a more pleasant & less fatiguing overall sound. I sat and listened to them for a few hours. Bass was excellent with warm mid's & high's. The ribbon tweeter used in the 20T's is a very expensive driver and you will hear why when you listen. The 20T's were driven by Krell evolution gear. This was about a year ago and I can not remember what drove the Andra's when I listened since I fell in love with the Aerial sound immediately.
If you are in the midwest my dealer was in Cary, IL - www.jpaulsdesign.com. He has them setup in his home which doubles as his studio which I thought was a nice way to demo them. I did end up buying the 20T's so I probably sound a little biased. I hope that helps.
