Well I have just had an evening of comparing Svara-L and Smabat ST-10. First conclusion is if you already have Svara-L you do not need the Smabat ST-10. The Smabat is an improved Svara-L, just sounds a bit smoother, less lively. As a Svara-L lover I would not want the Smabat but if I didn't already possess the Svara-L the Smabat would be a nice purchase though.
