I'm planning on getting an MA5300 for a 2nd smaller system. For an indefinite period of time I will be using it as a headphone amp with no speakers.
The MA5300 is a direct coupled amp, so I'm wondering if it will be safe for it to run with no load.
Also, when I do eventually hook up some speakers I'll be wanting to hook up a sub as well. The MA5300 has no 2nd set of pre-outs, and my sub has only RCA inputs. Is a 'Y' splitter between the bridged outputs/inputs the only way to hook up this sub? I'm pretty sure it is, but I'm wondering if this method compromises the signal quality or output voltage.
