but you should. I bought the OPAMPs last week from him.
Most guys in Hong Kong are serious (HK is not China scams)

Ah, my bad then.

I'll probably order my OPA627BP's from Tube_buyer, then. Now that I actually bother to look in detail, I can't help but notice the sides are rolled off, which is apparently a very good sign it's not fake.

Well I finally took the plunge and bought one, with the OPA627s already onboard. Can't wait to hear it!

Question: What should be the first thing I listen to? I want to hear something new that will impress me with good soundstage and dynamics to show off the Zero! Any recommendations? I like Jazz/World Music/Indie

(Lawrence has guaranteed the validity of the OPA627s!)

Yes! It arrived today! So it took a week to go from Hong Kong to The Netherlands, thats excellent shipping. I'm going to plug it in as soon as I come home (which will be about 4 hrs., pfff) and give you my initial impressions

That's really fast! Mine was held by customs for 2 weeks and came with an extra charge of €30

Enjoy!

Ok I opened it up, checked out the opamps, lifted one up, put it back in. Tried to listen to some music, BOOM. Opened it up again, and yes, I put it back in the wrong way . So now 1 of my AMP opamps is broken, anybody any solutions?

Just using the DAC part now, which offcourse still works.

So, one in the headphone amp is toast? Maybe someone in your area has already swapped out Opamps and can send you their old ones?? Just an idea.

That would be cool! Can you continue burn-in using the DAC section to another amp? Beats doing nothing I guess.

His shipping is REALLY fast, I just ordered some.
So far, I'm liking the 1364 best, the 1361 not as much. The 1469 is nice and airy, but the 1364's 'fatness' and low end performance is what I like better. Make no mistake though, the differences are VERY subtle. Don't expect miracles.
I still want to try the 627, but I'm not sure that the $40 + investment is worth such small results.

 

[vvanrij]

The 627's are also already ordered.

Upcoming week the following should arrive:

AKG 85
OPA627x2 + brown dog
2x LT1364 + 2x LT1361
Grado SR-325i
USB -> Spdif
2x Chopin CD

Its gonna be a good week

And Penchum, I'm indeed using the DAC, which is working awesome already! So the burn-in, do I have to do it all again when I plug in the new opamps?

No. The burn-in is all about the caps in the Zero. Once they are "settled", you should be good to go.

Since you aren't using the headphone amp section now, you may have to give it some additional hours later, because it has some caps in it too.

Ah yes indeed, btw there is no risk in me using the dac now, is there? The amp opamp is really blown up (litteraly to pieces), but as long as the Phone->green light is off, the amp section is not used at all right?

True. You should be fine using the DAC only.
