I recently replaced a Line 1 with the 3 & I couldn't be happier. I had a Line 2 demo unit for a month & that was excelen also.The 3 betters the 2 in the deep tight bass it produces. When I had the Line 1 in everybody was surprised by the bass I was getting with a tubed preamp.My only experience with the BAT is from hearing it at dealerships a couple of times so I can't really comment on it.The Sonic Frontiers is overbuil & the tubes are readily available.Due to their financial problems some dealerships have been dropping SF.My favorite dealer was one of them & I was able to get a new unit for 3K from them.With a litle searching you might be able to do likewise.The Line 2 has an A rating from Stereophile & the 3 is better sounding! Good Luck
