Either use your nail, or a screw driver. Rotate to whatever position you like. I would recommend you try different positions and see which one do you prefer. Just make sure both screws are pointing at the same direction. (There is an arrow mark one the screw. So it's relatelitvely easy to see...

i guess you mean Watson is a HYBRID design amp, rather than a OTL design amp, right? Well, OTL and Hybrid both has their merits and cons. Hybrid design will power those low impedance headphones, such as all those recent Planar Meganetic headphones, and also those traditional high impedance...

Strangely, I compared a pair of 2011 HD600 with 2014 HD600... and found the later one has much better bass response (bass extension is deeper and bass quantity is larger)... Then I compared the new HD650 with older HD650, and find the new HD650 also sounds much brighter than the older... So it...

First of all, I do aprreciate you providing those suggestions. As I'm just a head-fi hobbiest like others here, which means I'm no where as nearly informed as experts in electronics, I quite agree you said that "I should sharpen my knowledge". So surely something I said can be wrong or mistakes...

Not really. 1) Amp architecture type does affect sound quite much and plays a vital part regarding thhe sound performance --- otherwise most of the state-of-the-art and well established products won't be so keen on emphasizing their choices on Class A over other types. Even though circuitry is...

Couple things I have noticed between Watson and Ember II: 1) Watson is a duo-mono designed amp, which provides much better channel separation than Project Ember II. So theoretically, Watson has larger soundstage, better instruments separation than Ember II. The benefit of a solo-stereo design...

I didn't turn the amp off when turning the knobs, it's totally fine turning the knob while listening to the amp. And yes I was using a short screwdriver to turn the knob.

I use Elemental Watson's tube adjustment knob to adjust EQ below 3dB, and rolling new tubes for anything above 3dB. Since it's all anolog, everything sounds natural and smooth --- without those digital EQ harshness / stridency / sacrifice of image positioning / narrowed soundstage / ill-timed...

Just found the middle positioned knob sounds most neutral for Mojo (optical) for long listening seesion. Left positioned knob does have the sweetest tremble overtones, which gives the widest soundstage amd most open airy feel. For shorter listening session, the left positioned knob does sound...

Personally, I prefer to avoid any EQ. Ymmv.

You are welcome! I'm glad something I said can help you. As for $700 price tag for a Chord Mojo, I won't say it's not a worthy purchase... But it's definitely something a a little overpriced. For $700 I would expect something more versatile than Mojo... However, the truth is: There is no such...

Hi Rob, can you please tell us what kind of source device will support such a dual data output? Thanks!

Wireworld iWorld RCA cable has good performance for its price. And Wireworld Pulse RCA cable is even better, but also more expensive. It might be a great choice to start your searching/comparison from.

That's good to know! I hope nano under direct mode will bypass the amp part, to provide a clean 2v signal. I'm using Chord Mojo at my working place. The sound quality is superb for its price or size. The only complaint I've got is the soundstage being relatively smaller than what HD600 can...

Is Chord Hugo good for HD600? I mean the soundstage...
