Can anyone tell me if this LME49720 works with the LC?   If so, do I need one of those little heat sinks for it?

 

[Mad Max]

Totally. Heat sink?  I doubt it.

If you go to this link and scroll down just a tiny bit, you'll see the heat sink.  Maybe it's for something different...Dunno.

BTW, too bad the OPA-Earth doesn't easily fit in the LC.  A lot of people in the M-Stage thread are raving about it.

If only plastic was a good conductor of heat , than again if I recall aluminum is cheaper...  Those are socket adapters not heat sinks.  The standard LME49720-HE has a TO99 pin arrangement, where the standard for most op-amps used in audio are Dip8 or SOIP.  What you see there is a TO99 seated in a Dip8 adapter.
 
Best results would be to create your own circuit board so you could natively solder it directly onto the board but that is not a weekend project.

LME49720HA is excellent choice.It is very fast (I mean VERY FAST) and wide band opamp, and more prone to oscillations. It needs good coupling capacitors and demands good source (DAC) - without crap in signal.  If you want to compare to OPA2107 or OPA627 - don't. It does not forgive...  It demands the best signal on input or it will show you every crap in your recordings.
 
It goes hot (metal version) so TO-5 heat sinks are recommended.
 
Do not worry. It will sit in your DIP8 socket. I have LME49720 HA and there is no problem. You should use good socket (Nextron or similar stuff - not some "gold plate" fancy stuff).

You can solder in this wire at the bottom.

 

[Majestyk]

Regarding the 'heat sink'..Ok my bad.  HAHA.
 
As for the wire, that's what I was thinking.  I'll still have to get someone to do this.  Everything has to come out to do it and my soldering skills aren't perfect.

Since I'm at novice at this stuff, I'm not following this 100%...So can I use the LME49720 without doing any other modes to the LC Premium?  In other words, can I just drop it in the socket?  Thanks!

 

[BlaBlaBla]

Of course!

this amp is not appreciated enough!
 
I am still enjoying mine with the OPA627!
 

 

[ringer]

I'm appreciated I even made single ended pure class A amp for using LC as a preamp.
But I don't very much like OPA627 with LC. I think 2134 and 2111 are better.

Tried OPA2111 (bought in USA). Maybe slightly too dark and thin.  But man, vocals are stunning!

NICE,
 
where did u find it?
 
 

 

[Heidegger]

I want to buy one of these Lovely Cubes so I can compare it with my BCL. I'm not a DIYer, but I understand I can buy it assembled. Does the guy who sells this offer different opamps or will I have to do it myself?

 

[panda-R]

it comes with the 2134, you can get the dual 627 and the 2111AM(UK) from him.

 

[BlaBlaBla]

On e-bay. USA seller.
