I just got a pair of 22L2 also. I can't speak for the first series, but the L2 is not even remotely "light in the bass;" it is tight and authoritative, even pulling on a 50-watt Jolida tube amp. I am still breaking mine in, but so far I must second the comment about the harsh top, although only at high volume. The mids are great, female voices are consistently astounding, but turn it up, at least with my underpowered amp, and the treble starts to wear you out pretty quick. Hopefully they will mellow like cellared Bordeaux, but quicker...
Quad L vs. L2 series
Can any speak to the issue of the updated Quad L2 series? I'm thinking about the 21L(2) and just trying to get some overall feelings on the two. I've heard the 21L in the shop and enjoyed it greatly. I've read the lit on the L2 series and it looks nice on paper. I can't find any reviews on them. Has anyone listened to them?
