Which is the most important part of a stereo system?

It’s called a credit card....get one with zero percent for 21 months....then you can get a 2500 to 6000 dollar amp...credit cards are good tools if used wisely and lots of them give generous points back on purchases well a as a nice sign up bonus. For instance spend 1000 get 250 back or spend 500 get 150 back.....Like getting a nice discount on what you want. At 21 months @ zero % I’d say that’s a pretty nice deal. If not paid in 21 months, just transfer remaining balance to another good card offer and so on and so on....I always read posts whereas the person says I’ll never be able to get this or that etc...well you can if you use credit responsibly. Another good example is Music Direct. Every holiday they run a 0 % financing for up to 3 years!... probably the best deal in town. But, I guess I can see how some are afraid of debt...you only go this way once, life is short etc etc 😁
