I will try to keep it short and sweet so here goes. I have rotel ra04 se, marantz cd6002 and dali lektor 2 speakers. I want to upgrade the system and I would like to ask if anyone has put midrange amps like naim nait 5i or roksan kandy k2 into a system simular to mine and had worth while gains in sound quality. I know better speakers might get the best result but I feel that the rotel is lacking alot in many areas. I tested a audiolab 8000s in the same system and the rotel was put to shame, imo
