Not sure what I ignored sorry, perhaps it went over my head. I am just simply and lazily looking for an all in one solution to run my speakers and occasional plug headphones in.
Here's how I have it all working right now...
- Emotiva Airmotiv 4 with an XLR cable in each. [powered]
- Energy Power 10 sub with both L&R RCA cables. [powered]
- Both the XLR and RCA cables connect to my DAC.
- The DAC is connected to my computer via USB.
This provides audio to my speakers and sub-woofer, however if I want to listen to my headphones I have to unplug the sub-woofer RCA cables and plug in another set of RCA cables connected to my tube amp.
So what I'm looking for is something to replace my DAC that I can connect my speakers and sub-woofer into. On the now rare occasion that I want to listen to headphones it would be great if I could plug them into the 'new unit' without having to plug in a separate amp manually every time.
Heck what if it doesn't have a headphone amp and it's just for running my speakers and sub-woofer? I'm just surprised something like this isn't abundant.
The thing is that you're trying to get too many things done out of a single device. Most that have a DAC and dedicated subwoofer output are receivers that power passive speakers. Even then, you don't always need a dedicated subwoofer output if you were using passive speakers - some HT/audiophile subs take the signal from an amplifier's output stage (ie the speaker cable), runs it through an L-Pad, sending the same signal back out to the speakers while sending essentially a copy of it into the subwoofer amp. Change the volume, and the sub gets it too. Alternately, some integrated amplifiers have a preamp output, and sometimes a power input (with a bar connecting both in normal operation), so you can use a Y-cable on the preamp output of a NAD 304 for example, then hook up its power amp section to one pair and then a subwoofer to another pair.
Apart from what I've already enumerated previously the closest thing to all that is a Meier DACcord. It has a preamp output for your speakers, as well as a DAC line out for your tube amp. One problem: it uses SE RCA, not balanced XLR.
I don't see how that relates to what I'm looking for... Say I do get the sub what do I plug it into? I'm looking for something to plug speakers into.
You're missing his point, which was also a point I made previously: your speakers use balanced XLR and you want to send them a balanced signal via XLR, your subwoofer uses RCA. Your subwoofer was meant to be used with a dedicated HT receiver, or an integrated amplifier. This is how it is normally set up:
HT receiver >speaker output> FL, RL, C, RR, FR passive speakers
>LFE output> Energy subwoofer
Modern 2.0 receiver >speaker output> Left and Right passive speakers
>subwoofer output> Energy subwoofer
Older 2.0 integrated amp/receiver >speaker output> Energy subwoofer >speaker output> Left and Right passive speakers
(Look at the back - it has speaker cable push terminals, one set for input, one for output)
By contrast, here's the arse-end of a KRK studio subwoofer.
See any difference? For starters, no speaker cable terminals. However, it kind of works the same way as it has RCA In/Out and XLR In/Out. Here's how that gets wired up:
Balanced Preamp >balanced preamp output-XLR input> KRK 10 >XLR output-XLRinput> Airmotiv4
Alternately:
SE Preamp >SE preamp output-RCA input> KRK 10 >RCA output-RCA input> KRK Rokit 6
