itīs not necessary at all! Just dilute the PCR product to reduce the amount of salt, take an aliquot for ligation/tagmentation and go on. I tried it myself and it works quite well. I never compared the efficiency with a "standard" protocol, though. Based on what I see on the Bioanalyzer (havenīt sequenced any sample yet) I would be surprised to find out that the difference is so dramatic.
good luck!
