The only way to connect optical or coax to it would be to get another DAC that accepts optical and coax inputs and feed it into the RCA inputs, something like the Super Pro DAC707 at ALO Audio, or iBasso D10 or Headroom Micro DAC if you are looking for small and not too expensive (just now saw you have a Headroom DAC).

I didn't look for 6J1 tubes since Skylab contacted me after he saw a post I made about needing tubes and offered to sell me a very nice pair of Raytheon 6AK5 equivalent tubes. I understand Little Dot amps use these?
Anyway, the stock tubes I said in my review were still very nice - so, no worries there.

Right, and thanks. The SoundSource menu sound switcher is found at Rogue Amoeba | Quality Audio Software for Mac OS X I think.

I mentioned in the review that it uses 16V AC adapter, so it can't be used on a battery pack. So, since rectification is done internally I suspect it will be the same as with the DACMagic and not improve with a power supply - maybe with a power conditioner in your power strip?
It pairs equally as well with D10 and Pico, but the pico sits on the end-table to the left of my armchair with laptop on my right using a 6 foot USB cable, and the D10 connects with a 6" optical cable, so I didn't have interconnects long enough to reach the EF2 from the D10.

The D10>Gilmore Lite is still a more resolving system, so I can't say how you would like the downgrade. It is certainly transportable - just attach a foam pad to the top with a rubber band, and stick it in your brief case.

I just have a question...is there a way to connect a optical or coaxial cable to the EF2 somehow without degrading the signal? I am using a dvd player as transport, and i thought that if one day i would get the EF2 i may want to connect it to it. (although i already got a fine headroom dac i would also like to check the EF2'S built in dac) |

To make it easier to switch, you can download a menu extra called SoundSource that saves you having to open Audio Midi Setup. Neat looking little amp by the way, and nice review. |

I've reduced my cans setup to just a pair of hd600s and I could pocket over 300 dollars by selling my d10->gilmore lite setup and just getting the ef2 but I don't know if I should.... If I travel alot, does this device seem transportable? |
