Guys, I have found some source for opa627, USD11 ~ 16/piece for new one (shipping not included), some used one for serious value of just around RM20/piece, interested?

Interested on it but I have no idea on how to swap them

So for the Zero I would need 2 OPA627 and a Browndog adapter right?

Do you think can get the OPA627 already soldered on the browndog adapter, I lack the tools and probably the skill to assemble it myself

To swap opa627 into ZERO, you guys need 2 opa627 and soldered on browndog adapter, I found some soldered 627 on browndog, will research more before update you guys with the price

OPA627BP? or AP?

Test Seven: Burr Brown OPA 627 BP on Browndog adaptor Price: �28 each (Total �56 for 2 singles) Browndog adaptor �5 Total: �61

Two words sum this chip up........ "absolute class" This is the only single chip in the test (the rest all being duals) and it was necessary to fit two single channel 627's onto a single to dual Browndog adaptor which Adapts two single-channel DIP-8 op-amps to a dual DIP-8 pinout. These 2 single channel op amps absolutely trounced anything that had gone before them in this test..... the width of the soundstage, the clarity and the sheer presence make this my choice of op amp for use in the Chiarra without a shadow of a doubt. The sound is just so "clean", so "natural", so "musical" and so "detailed" with the 627's on board. I said the AD 823 was "as close to headphone heaven I have yet been" The Burr Brown 627 "is" headphone heaven....... absolute class act. 10 / 10



wow look at this review, it is BP. must do the browndog lah. his price too high, who can get cheper..

USD11 for BP & USD16 for AP



Is this the browndog adapter you guys mentioning about? Normally how much does this thing cost? I need some reference to nego with the seller if that thing is browndog adapter Seriously if those who are really serious about getting the best out of ZERO dac, should consider swap in OPA627 for the DAC section, 2 x OPA627 BP = USD22 plus another small fees for browndog adapter and perhaps some fees for DIY sifu to help u guys solder in, i think the cost should be just around RM100 and you get one of the best sound

Woot..seem like many people kena OPA627 poison...lol...
I can get OPA627AP at USD14 (including shipping to your doorstep) from oversea. But need to order mininum 4 pcs per batch (same shipping address).
It used to be USD12....but price increase out of suddent ....haiz..
But the browndog adapter (socket type) i cant find it cheap beside those at ebay and some online shop...ZZZz

hehe,this forum is famous for poison.bro,wan to ask what is the different between OPA627AP and and BP

LOL still no ppl confirm with me that the thingie inside the picture is browndog adapter?

yes..it is a browndog adapter..But need to take note izzit socket or solder on...
For opamp rolling, end user will prefer socket type...

That one is DIP Mike, how much you spent on this? Seriously i think i got a nice price

i still cant find cheap browndog adapter...
only can find reasonable price OPA627AP

guys...so sorry...me in the middle of moving office right now....so alot of things to do. need to setup cubicles, desks etc etc. so busy..now oso just only got home.

ive also confirmed a Maya44 with akabane. so hopefully he reads the PM i just sent him and mebbe can get the Maya44 tomorrow (friday) or saturday. then i can use the digital output on the card instead of the crappy mobo im using now.

as for ZERO vs HD2...dunno...never heard the HD2 before.

but... ZERO vs Fubar II+Cute Battery II amp... that one i know.

to simply put. the ZERO at almost 1/3 the price of the Fubar II+Cute Battery II, can seriously compete with them. there are some aspects where the ZERO is better...and there are some aspects where the Fubar is better. but the price point of the ZERO is a HUGE advantage imho.

@empire23

Is this the browndog adapter you guys talking about? Changing single op to dual op. I can get 5 for around RM10 if you guys want. There also the adapter to change SOIC to DIP.

wow..that is cheap..but is only the pcb board rite?
Browndog adapter that i lookin for is like below:


A complete with socket (DIP)
Can u find it? and how much?

Yup, that's only for the pcb board. The dip cost around RM1 for 1 unit and the pin around RM3 for 40 together. It's a little bit cheaper but lazy to do the conversion. It's selling separately so need to do some solder job. So should be around RM20 to get 5 set.

i prefer to have the complete unit. i leceh to do the soldering, my skill also no good. is it necessary to be silvered ?

If really available i want 2 units too (not sure where to use but keep it for future use DAH1's opamp is soldered so cant do anything about it )
