If u buy new at that price point ull get weaker amps were the sound falls down a bit. if u buy used u can get a much better amp for couple hundos and just add Bluetooth add-on if u must have that. I can think of many used sub $400 AV receivers that sound great (were $800+ new), h,,,ave necessary EQ and processing, with better power supplies. just check ebay completed listings and search at price point ur after. I like HK for cheap and Anthem for more... Denons used to be better quality...Yammies (have EQ) n Marantz make good as prepro's mated to outboard amps...Nad r notorious good sound but questionable reliability historicaslly....n don't like cheap onkyo sound.
