Editor,

Have you compared the sound between the Jeff Rowland 8T and Threshold SA-4e amps? I saw your article: "A Lifetime of Solid-State Amplifiers: Reflection on the Heavyweights." I'm trying to see if you've heard these amps and what they sound like. Thanks.

I used to own a Jeff Rowland 8T amplifier, and although I have not heard the Threshold SA-4e, I did own the class-A/AB variant, the SA-550e. Overall, both amplifiers are quite good, but I would have to give the nod to theThreshold. The one glaring weakness that the 8T had was in the bass: it sounded soft and woolly compared to any number of good solid-state designs. The Threshold produced much more powerful, controlled bass and an extremely focused soundstage. If given the choice, I'd go for the SA-4e in a heartbeat. . . . Jeff Fritz
