The S booster is a total Joke .I tried that ,in fast the LTA power supply is a minimum of 10% better. If you read what the Mojo illiminati-2 supply has in it add another 15% still
This is almost 13 pounds of regulation,and filtering
Far better then the Lumin S-1 power supply . In another league,
If you had over $2k I am sure you could better anything with enough $$ thrown at it. Never mind being a sceptic. Do like I did Buy it if not up to your expectations after 40 days,very long runin period over 500 hours+ . Just let it play. After 40 days keep it or not .You decide .but for myself and Many others my music has not sounded better.
