Just looking for thoughts on whether this idea might actually work!
I have an Ayre ax7e integrated amp which does not have a sub out so best connection to a sub would be from speaker terminals taking care on connections as this is a fully balanced design. This has been discussed previously in other threads and with Almarg. However in my system hooking up a sub like this AND alternatively using the tape out RCA resulted in a very audible ground hum especially on phono. This I could not get rid of so abandoned the idea.
Now here are my thoughts anew.
What if there was no actual physical connection between amp and sub? Surely then I should not suffer a ground loop hum? Started looking at wireless subs and there are a few hifi orientated brands than run of the mill HT units. One in particular I have been studying is the Martin Logan Dynamo 700w. This has a built in receiver and uses a transmitter that accepts RCA inputs and transmits on Bluetooth to the sub.
Sounds like it should work but.....
Anybody see any downside or has actually used a wireless sub?
I can commiserate about trying to hook up a pair of speakers and subs on the A7xe. Those binding posts make adding 2 pairs of cables a bit of work, but, it can be done. B
