That ‘baby GAT’ title could be a millstone around the neck of the ET6SE, but instead conrad-johnson’s latest lives up to the hype. It might take months to run in, but it will be worth the effort, as it manages to combine old-world charm with new-generation excitement all in a package that at once retains classic conrad-johnson characteristics and channels the best of the past and present in c-j’s preamp line-up. If it’s not the perfect form of a c-j preamp, it’s possibly only because of the presence of the awesome GAT-S2. That being said, you can buy almost three ET6SE’s for the price of one GAT-S2. As it takes so much from the GAT-S2 without that much real sacrifice in sound quality terms, the new ‘baby GAT’ is going to be a tough little blighter to beat.
