It's a Lenovo desktop installed in an old Carillon case (only the power switch on the front panel connected) with i5-4570 CPU, 8GB ram, and 100GB SSD. Windows 2012 R2 with Acourate installed. It's built in 2012 for configuring my 5-way diy speakers. Now the speakers sold. I will include the hard copy of Accurate Sound Reproduction Using DSP. Lynx AES16 PCI card installed. Please feel free to let me know your interesting with or without the Lynx AES16 card.
