I thought I had "the ones for life" with Polk SDA 2B's. Until I had to sell them to pay rent. For many years, little Tannoy R1's tried to fill the void, but left a big hole. ADS L710's satisfied for a few years, then L1290's for several years. Those got sold when I fell for Snell type D's, which remain my fav's until I can step up to the Aerial 7's that smote me a year or so back. I enjoy some Snell K.5's occaisionally, and out of nostalgia, plug in the ADS L710's, but currently none can take me away like the Snell D's.
I do watch constantly for some Aerials that fit my budget, but it'll take a pretty special deal on them to displace the Snells.
