No not at all. Pick up the Cardas rca-xlr adapters readily available. They are a high quality adapter that wont degrade the signal in the laest IMO and will allow use of the 5. You may need a pair for your output to your amp also.(XLR-RCA config) They ususally go for about $50 pair..it's still cheaper than changing all your cables or components. Well worth the cost to be able to use the LS5. Alot of folks are intimidated by the all balanced in/out of the LS5 or figure its not worth changing their whole set up. IMO this pre amp IS definately woth building around it, The Cardas adapters will allow you to have your cake. :) Ken
