I have a pair of Martin Logan speakers for L/R setup and im using an Topping TP30 amp for them. I also have an Martin Logan powered sub that I would like to add to the setup. The problem im having is that none of these small desktop amps have an sub output. I only have outputs for me speakers. Also the amp has a built in DAC so its connected to my computer through USB. The sub does not have high level inputs, only two L/R RCA plugs for input. Can anyone help me figure out how I can connect the sub to my current setup? Any help would be greatly appreciated..
Need help with Subwoofer
Gear mentioned in this thread:
What do people think? Should suffice right?
(One for each channel of course). I suggest using RCA-cables (either build yourself or buy) so they're mono (and not doubled/linked together)...

I was told I may need a line out converter. Ive looked at some but they are all made for cars. Does everyone who uses bookshelf speakers just live without a sub? All the small desktop amps ive looked at, lack a sub out. I would love to find a small 2.1 amp or even a 3.1 with center.

Any receiver with an optical input should work.
Should be able to find a used receiver of Craigslist for $100.
Or eBay for $150
Personally I like Yamahas because they come with Silent Cinema, which is Yamahas surround sound for headphones.

Im trying to keep this as small as possible. I have a full size Yamaha receiver but I don't want that on my desk. I'm currently using an Topping TP30 desk amp. I like the Cambridge One+ because its also a small form factor. Does anyone know why these small amp's never include a sub-out? That's really all I need. My sub is powered and does not need power from the amp, only the signal.
