  If you think that sounds good, just wait until you try the V5 in a Supreme Sound Lycan. You'll think you died and went to heaven. If you can, put it on your future purchase list (it's very affordably priced). After hearing the Lycan, with the V5, the Matrix M-Stage will sound slow, and sloppy. I really want to love my Matrix M-Stage again, but the Lycan is just so quick, with every musical note. Vocalists sound like they are standing right in front of you, singing to no one else but you. BTW, what is your current headphone of choice? 

The only place that I can find that sells the V5 is Austrailia,

HPA-1 revisited

I just got used HPA-1 from ebay. To my surprise when I open it I have noticed that condensators are scratched:
 
 

 

 
Any thoughts please?
Is the production quality so poor?

There are a couple of scratches on one of the capacitors in mine. It's about 4 years old and still works great. I wouldn't worry about it.

Those are not scratches. Take a look at the small electrolyte capacitors. There are lines there as well. They are strategically weakened parts of the casing which will bulge upwards and help the capacitor release hydrogen and/or electrolyte in case of pressure build up due to overheating.

Besides of that you can seee there are some scratches also. It's strange but if it works well...

Received mine today, but not had a chance to listen to it as I'm at work. Hopefully have some impressions this evening, test it with the Fostex TH500rp, Beyer T1 and others.

Every time i want to listen to my speakers i have to plug out my headphones.
Is there a way to mod the amplifier so i can have a switch between headphone out and line out?

do somebody know how the Matrix M Stage HPA-1 with the Burson Audio V5 SS (Supreme Sound) op-amp chip compares to the Gustard H10? Im asking because the H10 is on massdrop for a great price, but if I get a lot of its performance by upgrading my Matrix with the Burson op amp I will safe some $$

 

[Mad Max]

Rolling opamp tunes the sound to a degree, can get you a small performance boost if you use something like LME49860 or OPA827, but from what I read, slight changes won't be enough for M-Stage to compare to the H10.  You're better off going with the H10.
I intend to as well, later.

 

[Plougski74]

Thanks Mad Max - I ended up buying the Gustard so looking forward to see how it performs.

Anyone tried pairing the Aune T1 & the M-stage HPA-3B before? Planning to get it for my AKG K7XX.. Also have the Fostex TH-X00 coming in september but I'm not sure if I'll use that headphone with this setup
