I'm currently building a low to mid range HT system. It's going to consist of PSB Stratus silveris, C6i and mini's for surrounds. Also have a Velodyne cht-10(very curious what you might think about this model). Also planning on purchasing a new receiver(eyeing NAD 763 or 773). Currently have denon avr-1700, the PSB Silveris, Athena ASB1's for surrounds, and above mentioned sub. What would you folks recommend as an order of purchase? Need center, surrounds, possibly a better sub and a receiver(or pre/pro but not sure I can comfortably afford a proper setup). I spent $350 on the Velodyne cht-10m but can take ir back if needed. Keeping in mind that all but the center and sub will be 4ohm, what might you prioritize if this were your system? Thanks very much for any advice!
