This is my streamlined system as of 12/12/2017. I've added an Oppo BDP-105 but removed a Parasound AV-2500 surround processor and VTL 2.5 TL preamp with HT Bypass and NOS Mullard tubes. It's used for both 5.4 surround ht and 2-ch music listening. The Oppo BDP-105 now serves as the center of my system; used as the sole disc player, preamp, surround processor, DAC, All amps are connected directly from the Oppo; the main L+R Magnepan 2.7QR speakers driven by a pair of D-Sonic class D M-600 mono-blocks (1,200 watts @ 4 ohms) via XLR outputs, Magnepan CC3 center channel speaker driven by a bridged Emerald Physics EP-100.2 class D stereo amp (375 watts @ 4 ohms bridged) via SE output and Infinity in-ceiling L+R rear surround speakers driven by a Class D Audio SDS-440-CS class D stereo amp (220 watts @ 8 ohms) via SE outputs.
An Audio Kinesis Debra 4-sub bass system (virtually identical to the Audio Kinesis Swarm system) all 4 4 ohm subs are driven by a Dayton Audio Sub Controller/Amp (995 watts @ 4 ohms). My entire CD collection and numerous 24 bit/96khz hi-resolution music files are stored on a Synology 2 TB hard drive with a Seagate 2 TB backup hard drive. A laptop running JRiver controls the file selection to send to the Oppo's dac for conversion to analog and playback.
I recently added headphone playback to my system consisting of my laptop, JDS Labs OL usb Dac, Aune X7S class A headphone amp and Sony MHR-7Z headphones.
