You won't regret the VAC upgrade to SE but mine took maybe 200 hours of break-in but worth it in the long run. I have ordered the AM beeswax for the VAC to compare to the SR RED in it now. The front end should tell some story on the backend with flavor to balance the system without going nuts with everything. These fuses are bargain flavor balancers and SR sure has changers a plenty. OMG what next?
