Those op-amps are very tiny.

I bought 10 LME49990 chips and the adapters and solder and the solding iron.

When I finally open the box with the bare op-amps, and saw how small the op-amps are, I knew I was in for problems.

(Me having 48 year old eyes, is also part of the problem with soldering little op-amps)

I wish I had just bought the pre-soldered, before wasting my cash on "parts".

I ended up buying pre-soldered AD797BRs from China.


Like I said eBay isn't an option really. I only need the opamps for the I/V (I only use the HP amp, so the buffer isn't used).

 

I'm leaning towards 2xTHS4032 and making my own adapters (which isn't an option with the LME49990), soldering isn't a problem since I soldered tons of SMD chips before.

 

Looking on Farnell I see two versions of THS4032:

- THS4032ID

- THS4032CD

CD is cheaper for 2€ but I can't find any difference in the specification PDF...what's the difference.

From what I've read the THS4032CD is actually mil-spec, so it might be the better one. I bought 3 of these, if your wondering.

Edit: Not sure anymore

The "ID" can work in a wide temperature range then the "CD".

       +85c to -40c                      verses                         +70c to -0c

I see, thanks to both of you, I guess I'll just grab the ID's then.

 

Sylverant are you happy with them or do they lack in certain areas? I'm coming from 2xLME48960NA which do lack a bit of bass however they sound really nice to me.

But if the THS4032 are better I'll try them and decide which to use (using HD600).

I also don't get the shipping thing. I'm in South Africa and shipping was fine- btw i bought from ebay (hifiic)

I had thought I read somewhere that the CD was mil-spec, but from the data PurpleAngel found (which I looked around for and found as well), it seems that the ID is most likely the Mil-spec model. If you look around and find those that would be great, but the THS4032CD are working just fine for me.

I am happy with them. I wasn't originally unsatisfied with the stock opamps soundstage size, but felt they lacked a certain level of instrument separation and placement. I basically agree with WiR3D on their sound; the soundstage gets a little bigger, along with a big improvement in imaging and speed. Their also smoother on top compared to the stock ones. I wouldn't call them bass crazy by any means, but they do a good job of bringing out the bass in unboosted jazz recordings like Jazz At The Pawnshop. I should probably let you know that I am using the AKG K271(with 30ohm adapter)/K400EP and HD560 with the STX,all of which are bass light compared to your HD650, so you'll probably get better results in regards to bass than I do. Overall I would say they're pretty balanced, which is why I like them.

I don't know however, how it compares to the LME49990. It's possible that you'll experience a slight drop in soundstage size moving from the LME48960NA to THS4032.

So this review above relates to the THS4032? It sounds like the sound I want to balance out the dark sounding 650's would that be a fair comment? 

 

Sorry to be asked to be spoonfed, but I need a plug and play solution, is this what I need x 2?

Thank you, thats exactly what I was looking to hear. I guess I'll order 2 of them then and see how I like them compared to what I have now.

Have any of you tried the Muses chip that Asus is using for the Muse Edition inside of your Xonar Essence ST(X)?

I was curious if it worked and how it sounded if it did.

Thank you in advance :)

say what?

The opamp chip that they are using in this: http://www.6moons.com/audioreviews/asus/1.html . I was curious if anyone had yet bothered to try it in the Essence ST or STX.
Sorry for the confusion.

what a disgusting website/ article layout. Made my eyes bleed. But no I haven't tested the muses opamp, and would actually be curious how the under specced over priced part performs.

post #3899 of 4953
I just got 6 LME49990 opamps to try out. (Among a bunch of other opamps) What is the DIP adapter I need?

Will this work?

Or is there an even cheaper version out there?
