It has begun!

Mike

5532D is old school, at best for comparison only.

 

LME 49990 or if you can't afford those single channel needing adapters then use LME49860NA which is dual channel. If you did nothing else, you would survive just fine with the LMEs. A plus is being able to buffer the LME with a couple of LT1028ACN8 and that would be a benchmark to try and beat.

 

This french girl's voice seems to be captured by a great pickup opamp (and mike). Her previous rough videos all do a fine job picking up her voice. She is no Frank Sinatra where I swear the guy could create a note when inhaling because you never hear him breathing but none the less this girl processes a clear voice. http://youtu.be/UQUXB57BWPM

Wait until you start doing more:

Yeah I will do more,with two more on the way,but I want to keep it limited to the one amp I can roll opamps with.

Bump this thread.. Have you guys ever try LT1366 or LT1368 ? I will place in FiiO X1. I found my X1 sounds not right to me, I think it too thick and forward. So I did a little mod in analog section. There are two opamp after DAC, OPA2322 and ISL28291. I don't exactly know what that purpose, since the DAC PCM5142 has internal buffer I/V itself. The output DAC should be already 2V. I think it kind of buffer headamp without voltage gain. OK its too technically for me. But my main concern is the sound. 
Just see into the specs and from this site http://tieba.baidu.com/p/3323609195?pn=1 , both opamp are RRIO, and operates 2.5V. So finally I change OPA2322 > LT1361 and ISL28291 > LME49721. LT1361 run nicely though that is not RRIO. I want to try LT1366 and LT1368, but I didn't find any comment about these opamp.

I might have tried 1368 in the past and thought it sucked.  I haven't liked any LT chips yet, it is best to stick to Analog and TI chips for audio, I think.  OPA2365 is a real nice chip, I'm told, and it is rail-to-rail like 2322 with the same operating voltage range.  I haven't tried it and don't have any equipment that I can use it in.

Thank you, I will try opa1612 then.
