  Just put up my HPA-2 for sale if anyone in this thread is interested.

 
And I just sold mine, I guess I'm kicked off the thread!

 

[Change is Good]

Wut?!?!?!?!?!?!?!?

Did you sell the HPA-1 or HPA-2?

 

[conquerator2]

Why so many sales all of a sudden? Are people not happy with it? ;/

Oooops, to clarify I sold my HPA-1.
It was the slightly older one without the little ventilation holes and no crappy USB connection.
I'm raising some cash to buy a Matrix Quattro Balanced headphone amp.

Selling mine because the Project Ember took over. And a dedicated DAC.

I had no problems and no complaints.
It's a nice amp for the money, I'd recommend one to anyone looking for an amp in that price range.
Has enough power to drive almost any 'phone.
Sounds better than my FiiO E09K or E12.
 
I just have a bad case of "I wanna upgrade!"

I have noticed tha the right ear sound is significantly lower than the left. Any ideas what the culprit is? Switched different opamps, wires and tried my headpones on different amps.

If you have the original version with the gain switches on the bottom (like I do) then you may have the channels set different for gain (easy mistake to make). If you have the new model with the fixed gain and you have switched opamps then I am afraid it is service time.

Thanks Chodi. I hardly ever look at the gain switches. I even forgot they were there.

Since my Matrix is back. I popped in the Opa-amp LME49990 in. First impressions are airy and wider soundstage than the 4562 I had previously. Less bass and more dry sound. I don't think I have noticed much burn in with opas in the past. But I don't like the sonics of the 49990 as of now. So I will give it 50 hour of burn to see if things change. I was looking for something with a more fluid quality. The 4562 has too much in the highs especially vocally. But the wet sound and great bass is the reason I keep going back to it.

Mmmnnn very exotic looking. If the 4562 has a little too much gain. Would this be okay for 25ohm Denon headphones?
