Hi there! I'm looking for recommendations on quadraphonic amplifier with HDMI & network. I currently have 4 KODA speakers, 4K SONY Android TV, HP Server and Apple devices. I definitely want to go for quadro setup, with quality sound over HDMI from TV. I would need few inputs to plug an iPad (or connect wirelessly), Allen & Heath Xone:32 dj mixer and the Focusrite Saffire PRO 24 DSP sound card. Thanks in advance! Lakis
