Brief Odac impressions - Page 125

post #1861 of 1873

Thanks for the replies guys I'm assuming these two wires would work:

 

So the line out cable to the ODAC then the other end to the splitter which connects 1) speakers and 2) O2 amp for headphones.

 

I do have to convert that 3.5mm to RCA because my speakers only have RCA.

Am I losing too much signal by doing this?

Or you could do what I did & buy this...

Yes but I still have to split the RCA from the ODAC to the O2 and speakers? I feel like connecting the O2 to the speakers would cause double amping unless I'm wrong.

No you don't. The O2 in my link has a pass-through facility. You need to be careful with O2 volume but otherwise it will work fine. I specked my O2 with gains of 1x/3x. This allows me to leave it in 1x gain and when I'm listening to my Marantz amp I make sure the O2 volume is at max. It works a treat. I don't see any reason why it shouldn't work with your Rokits.

Put it this way - it better work because I'm selling my integrated amp with the intention of buying active monitors, possibly even Rokits.

Edit - hold that advice. I've read it back and I'm not sure either now. Perhaps the O2 volume should be at zero. Hopefully an adult will be along soon to help me.

Best get a passive preamp to go between the ODAC and amps, safest and cleanest option. You could even make one yourself :)

So PC>ODAC>preamp>O2> speakers + monitor?
 

How would that help, exactly? I feel like you're still double amping the monitors in the end.

Hi all,

I use two ODACs, one in my office setup with short USB cable and the 2nd in my home desktop setup with long 2m cable. The 1st works fine and stable, but the 2nd sometimes looses connection with MS Windows 7 (no sound). Unplug-plug or restart of the PC helps, but it is not good way in the desktop system to reset.

Is there any software way to reset the USB device in Win7?

PC>ODAC>preamp - >O2

                          \

                            ->speaker amp/active monitors

 

With preamp's switchable outputs ODAC sees only one load at a time, which is optimal.

 

Btw, "double amping" with O2 is perfectly acceptable, in fact I wouldn't be surprised if it provided cleaner voltage (gain) than the amp in active monitors (should be enough for a small room voltage-wise). If you kept active speakers on low volume you would get clean voltage from O2 and enough current from active monitors amp's output stage, best of both worlds but that's a bit "overengineered", Preamp option is a cleaner solution (less cable clutter on your desk).

Isn't the O2 effectively a pre-amp when hooked up to active monitors?

Now the hard part, how much would a decent preamp cost? I just thought of something though which will greatly help me if this way actually works:

PC>Aune T1(which I already own, using tube DAC only) > O2 > headphones

           \

             > (RCA to speakers)

 

Sorry I know this is the ODAC portion but I just figured I'd update you as I update the LCD-2 thread as well. I'm looking into the O2/ODAC combo because the Aune T1 can't drive the LCD-2.

Shiit has one for 50$, it has 2 inputs and 1 input, I'm not 100% sure but as it's a passive preamp you could just connect it the other way around: O2 and speaker amp as inputs, and ODAC as output, and shwitch between them

 

Im not sure if Aune has 2 sets of outputs but you could probably just bypass it's head amp, or simply use to to drive O2's input.

post #1872 of 1873

Would you guys think that analog crossfeed is a worthy addition to O2?

 

What else apart from second set of outputs do you find missing in the stock design?

post #1873 of 1873
I'd like crossfeed too. And he left out the laser light show on my ceiling.
