+1! The Bassos are classics as far as I am concerned. I'll probably do a big purge one of these days, but the Bassos are never going nowhere!
The Bassos are like a relaxed listening version of the the 1K's. Similar beautiful signatures, but the bass and treble is a bit more relaxed with the Bassos. I actually enjoy switching back and forth between them depending on my mood and music, so I am happy that I have both. Then again, I don't have the EPH100 or S2's on the way! But it seems that many people prefer the Basso's (or is it the Tenores?) to the EPH100, so.... the decision is up to you!
