Wondering if anyone of you guys have tried the Objective2, I hear it's as good as some desktop amps.

The O2 seems to be an excellent portable amp and matches well with the Audezes. I have placed my order for the O2 and will be testing it with my LCD-3. Will post my impressions once I have listened to them.

^ I talked about objective 2 amp in the previous page of this thread. It is as good or better than lots of desktop full size amps. M3 or CTH are not much better when paired with my Lcd2s. I do like beta22 a little better than o2.

What gain setting do you use for the O2?  Where is the volume position usually?  I realize everyone listens to music at different volumes, I'm just trying to get a feel for what gain I should build my O2 with.  Thanks!

You should build your O2 with enough gain so that you can get a full 3 Vrms with the source you plan to use.
Anyway, you have two gain settings with the O2, you can use the other setting as a lower gain option if you plan to use IEMs, or a higher gain option if you plan on using weaker sources.
You could also get more help on diyaudio.com.

Completely agree. It competed very well with my Apache

@ rmlink,
 
To answer your questions:
 
"What gain setting do you use for the O2? "
 
>>>>>> Not sure what gain it is. I bought my O2 from JDS labs as a finished product.
 
"Where is the volume position usually?"
 
>>>>>> I usually listen at 78db-83db. With iPhone 3GS HO set to 90% as source, volume pot of O2 (always on low gain) with Lcd2s is around 10 o'clock, around 11:30 o'clock with 600 ohm DT880s, 8-8:30 o'clock with Westone ES3Xs. 3GS HO's output is higher than Sansa Clip and lower than almost all desktop dac. An of course, some recordings are recorded with low volume (classical, instrumental music) and some with high volume.  
 
>>>>>> For my headphone listening, I usually select a gain of 2X (I rarely use any thing higher, although gain up to 6X is manageable though it will limit volume pot range). I guess the default low gain setting of JDS O2 is around 2X, while the high gain is around 6X. But I am guessing with my ears, so please take that with a grain of salt.

Okay. Who is building finished O2s? I have to try this bad boy out. I need a new portable amp anyway...
 
Has anyone done a comparisson with the HP-P1's amp? I'm considering that in the future as well.

JDSlabs is selling them finished, and I think Headfonia compared the two.

Lake People G100 (along with the V200 from Violectric) is also a good match to the LCD-2s.

Yup. I was at a mini meet recently and the host's wife actually thought it sounded better than his Apache with her limited listening experience

You mean an O2 feeding LCD-2s compared with the LCD-2s fed from an Apache???
(quite a shocker if I got that correctly)

 

[Girls Generation]

Apparently it competes with a B22 which I believe is quite insane for a small portable amp that costs $140 .....

Remember, don't panic.
