Cooperdude: I have not used the Sbooster, and by most accounts it is pretty good, just a little bit too much money for me.
As to the Chinese linear power supplies there is a pretty big difference in performance between, say for example, the ultra cheap BRZHIFI or Weiliang 15W transformer based LPSâs (even with the upgraded Talema based transformer as opposed to the less expensive Bingzhi transformer) and the marginally more expensive R-core based power supplies that sell for just a little bit more on Aliexpress.
I would avoid the low cost Weiliangs/BRZHIFI's (generally around $70-$100 Cnd. and step the price up slightly into the $115-$150 Cnd. (about $90-$110 USD) R-Core supplies with a decent power cord. Much better performance for not many more $$.
IMO based on owning both. All linear power supplies are not created =.
