I wanted to do a quick update on the 1801-TL purchase. I'm very glad I bought the 1801-TLs as they are mint and sound excellent. The most obvious improvement in my room is the added bass response. The midrange seems a bit more detailed over the STs but the difference is subtle. I ordered a single 1801-b from Jim yesterday as I feel that will be a better match than using the Song Center.
