Over time I have used various Weller desktop soldering stations, and have generally been happy with them. However, recently I was able to use a JBC soldering station for a while, which made me an instant convert. Thus I recently bought a JBC, one of their smaller models, for hobby use.
As seen from where I am sitting, then the Weller soldering stations are not even on the same
planet as the current JBC models. Particularly if you occasionally solder 'heavy' connections, then the heat recovery of the JBC technology is amazing. For instance I recently found myself soldering and replacing connections to a mild steel chassis (don't ask) while just using a 2mm chisel tip. Even though I do have a larger tip, then just using the 2 mm worked just fine.
Audio gear frequently has heavy duty connections due to the high current circuits found inside amps, so this may be an important consideration for the OP.
Could I live with a Hakko or a Weller? Sure, but I much prefer the JBC.
I have never tried any ERSA or Pace models, at least not for any length of time, so are unable to comment on those.
The sole reason the small, desktop Hakko and Weller stations gets people's vote in place of a JBC, can only be that the same people haven't tried the JBC.
