I recently purchased a Rel R-528 sub, which features a high-level input as well as the LFE connection. Rel insists it is mandatory for the front speakers to be set to LARGE to take full advantage of this sub. After much experimentation and advice from AVS members in the Marantz 8801 thread, I have found the best results come when in fact my mains are set to large, and the LPF on the Marantz are set to 250Hz. I am EXTREMELY happy with this set up. The high-level connection on the sub gives me exceptional bass, even when I play two channel music from my Mac Mini music server into the USB input of the 105.
My question is in regards to the settings for the 105 with this configuration. Should I set the speakers to LARGE in the speaker configuration settings of the 105 as well? I understand these settings don't apply for the USB input or when listening to DSD output from SACD, but for all other material that I listen to through the 105's DACs (DVD-A, CDs), I'm not sure how to configure it.
Thanks in advance.
