Aww man.... and I just spent a ton of $$ (a ton for me anyway) on an EF5/HE5 combo! (which just showed up at my house today!

)

In fact that's what I was going to post about, that it seems my Jade has a bit of a hard time driving the HE5 - which have definitely been described as current-hungry. I have to turn up the volume quite a bit more than with my other headphones, as their efficiency is lower even though the impedance isn't that far different from my Denons. And there's some distortion when things get loud and low (e.g. large orchestral works). Guess I could also try 5998+12AX7 instead of what I have now - 6AS7G+5751 - to see if that gives it a bit more oomph.

I've ordered Joe's high/low impedance transformer, hasn't shown up yet... will be interesting to see if it makes any difference.

Awesome! Can the A3 work as a preamp?

Thank you Joe

Glad you got it!

It will have 2 version. 1 is full headphone amplifier. 1 is with pre-amp out & 3 Input.

what's the price tag?? any upgrade options like Jade??

or even...... trade-in program??

I received my Jade today with balanced cable for HD 600/650.

I can hear the difference with stock cable using either left or right output. Can someone confirm to me which output (SS/tube) I get from using the balanced cable with both outputs?

 

[ecclesand]

Has anyone tried a 5965 tube in the Jade? It has a higher heater current draw than the 12AX7 or 12AT7. I wonder if the Jade's trafo can handle the extra juice. I pm'd Joseph to see what he thinks. I have read that the 5965 has better sonics than the 12AX7 and 12AT7.

Is the Jade A3 going to be a higher end version of the current Jade?

I think it's the tube output.

I've been listening to Jade + JVC DX1000 for the past 5 days and I am thoroughly impressed! With the tube output the imaging, soundstage and (deep) bass are nothing short of stunning.

The SS output sounds a little bit too polite.

Highly recommended!

Jade-A3 use same topology as Jade but use difference output tubes only. It is not upgrade but use difference tube to have difference sound signature only. Jade - 6AS7/6080 low impedance drive capacity is better than Jade-A3. Jade-A3 have magic of direct heat tube.

I'm sure other folks have probably already done this, but today I replaced the stock film caps in my Jade with some Multicap RTX (polystyrene film/tin foil) and yowza! After about 6 hours of burn in I am hearing improved detail and a more 3D soundstage. Does anyone else have any impressions with different caps in the Jade?

Hmmm....I wonder if replacing the electrolytic caps would yield any improvements?

Sure ! Replace better electrolytic caps can improve to much better. Jade still can dig deeper to have better sound. You can parallel a small value film cap with e-cap to improve sound quality.

Any tips for a noob interested in doing this?

Thanks a lot for the early impressions, please keep us updated!
My interest for the DX1000 has cooled off a bit but only because I blissfully enjoy my HD650 with the Jade (currently settled on pseudo-balanced with Chatham and Siemens ECC801S). DX1000 is likely my next purchase but there's no urgency anymore
