Am going to build my first hifi system. Have zeroed in on the elac b6.2 speakers. Have heard very good things about them. However I am super confused if I should get an integrated amp like the mrantz mcr511 or a 5.1 av receiver like the yamaha rxv485. Would love to hear your inputs on the road I should take. Ill mostly stream music but would like to have options for future upgrades!
