Where did you order them and which ones exactly are those Burson OpAmps (model number?)?
Is just one pair required for the Phonitor as well or does it need more than the Auditor?
Thanks!

I ordered straight from Burson. Single OPAs with dip sockets. They are sold in pairs (you need a pair).

Thanks. Not sure I understand yet exactly what I need.

1 x Single OPA DIP or

1 x Dual OPA DIP ?

Or 2x any of each?
 

Are the OPs in the Phonitor socked so that it is really just a plug and place. Or is soldering/unsoldering still required with the DIPs?

Let me point you in the right direction....

An alternate (if you want something more perminant and have decent soldering skills) would be the flying leads version.

You might find a better price elsewhere, but at least you know what to look for.

Single OPA dip socket 70AUD. You order one package where there are two included.

I currently have Audio GD sun and like it a lot, more than the stock opamps because they are more musical, have more bass but still very detailed. But it really depends on the DAC. The stock opamps work well with the musical wolfson whereas the Ref5 with the pcmuk chips was too boring.

I didn't know much about opamps either, I first ordered two dual opas (Moon). The amp started smoking, luckily I had the amp opened and shut it down instantly when I saw smoke. It didn't damage my amp, I might have just slightly re-flown the solder. :P

All you have to do is drop the opamp into the sockets so that the half moon on the opamp and amp socket align. You will know what I am talking about if you open your amp. There will be a half moon looking mark and you have to position the Burson the same way.

You will also need extension leads, you can order those from Audio GD otherwise you won't be able to close your amp, unless Phonitor is higher.

The Phonitor is taller so there's no worries about height clearance issues like with the Auditor. 

The Burson OpAmps with DIP adapter will fit inside the Phonitor just fine .

Thanks guys! Can someone confirm that with the DIP it is really just an unplug/plug in job & no soldering/unsoldering is required with either removing the old OPAmp or placing the new one?
Thanks!

its like inserting a sata or IDE cable if that makes sense to you. You need to insert it the right way but its really easy. No soldering required.

+1

 

 

You only need to solder a pin or two if you are going to be moving your Phonitor around a lot.

Soldering in this case would help prevent the two Burson OpAmps from falling out of their socket during transport.

The Burson's are much taller than a regular chip OpAmp (what is stock in the Phonitor) and are top heavy.

If you aren't going to be moving the Phonitor around than soldering is not really required.

 

BTW, when you drop in the the new OpAmp, be sure to snug them in firmly, but gently - last thing you want to do is break a pin!

Also as .Sup said, make sure you align the pins of the OpAmp in the correct orientation, failure to do so will lead to a fried OpAmp.

Ha! Jamiee so when I was trying to pair a dual opa with Auditor and when I saw smoke it wasn't from the amplifier but from the OPAs?

Lol. Yeah I'd say it was Most likely the OpAmp.

That said, I'm not sure why the dual channel OpAmp would have burnt up like that?

 

The only time I've seen an OpAmp burn up straight away like that was when it was inserted in the socket incorrectly (read: backwards).

As soon as power was applied to the board, *POOF* went the OpAmp!

*Edited.* Oops, already answered my question.

post #387 of 678

Anyone got a picture of where exactly these go in the Phonitor? I haven't opened mine up since getting it, and even then I'm pretty much a newb, so I wouldn't know where to look for the stock opamps anyways. Certainly a fan of anything that I can plug'n'play and get a significant improvement out of, though.

Here you go....

Do you happen to know what these 2 OpAmps are used for and their type? I thought it was mentioned somewhere in this thread that any OpAmp other than the SPL propriatary ones were not in the signal path. or maybe I got that wrong.

Didn't open up my Phonitor yet.

Thanks!

Jamiee surely you need an extension lead to insert a Burson opa there no? The two capacitors next to each other op amp are awfully close.
