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.


Thanks.

The Supra OpAmps by SPL are discrete built so it doesn't make sense to insert bursons there I suppose.

I was referring to the two OpAmps that are circeled in yellow in the picture above and which are supposed to be replaced by the Bursons as far as I understand. What model are those and how do they affect the signal path.

I'm curious about this as well--I've read that the opamps in the Phonitor aren't actually in the sound path, and instead are present for the purpose of 'DC offset,' whatever *that* means. @.@

The chip op-amps in the Auditor and Phonitor are used purely for DC-offset control and play no part in the audio signal path.

Changing them cannot possibly alter the sound in spite of what some people claim they are hearing.

Suggestion is a powerful force. Don't be fooled.

I don't believe this. The difference is night and day in my Auditor.

Lol. Maybe I'll have to contact SPL and get their opinion on the matter. Which probably won't be much of an opinion.

SPL's response has aleady been given in post #329 of this very thread:

Hmmm. Interesting. Thanks for the link.

The marked OpAmps are not SPL's Supra 120V units.

They are used for some sort of voltage regulation (though for the life of me I can't remember what), and while SPL claims that changing them won't affect the sound - I can tell you that it certainly does!

 

As for spacing - The Burson will fit fine on it's own without any additional adapter for added height.

They have just enough clearance over the small capacitors you see in the above photo.

I have tried Audio GD moon and Sun besides stock Supras and they all sounded very different.

So do the Bursons not actually sit on the board? I get that the pins will be firmly in place, but the actual chips the components sit on just sort of... chill? Can you tell that I lack the vernacular to properly discuss this lol?

 

Anyone got a good picture of what the Bursons look like in the Phonitor when they are installed? I'm trying not to be too needy, honest. ^^

Yer gonna make me pull out and open up my Phonitor aren't ya....  wink.gif

Well, I'm not going to make you, exactly... I'll probably just keep gently bugging people until I get my way. :-D

Lol.

 

Well lets see if this will tide you over for a bit...

NOTE:  This is not a Burson installed into a Phonitor - but it looks exactly the same.

I should also mention that the burson in this photo looks to be a dual-channel part (the single channel version is very similar looking - just lacks the added componentry on the backside).

yep, on the DIP adapter all you have to do is line up the half moon (semi-circle) with the matching one on the socket.
