TL-082 Although general purpose, it is pretty good at producing bass. AD8066AR needs an adapter but handles bass really well.

  The original gold/purple AD700 have a bit better clarity and staging plus a cloth wrapped with better wiring cord and more comfortable shaped ear pads and some magnesium construction. The specs read better on the AD700X with sensitivity at 100db versus the older AD700 at 98db but the AD700...

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...

A lot of times you will get clarity and not know it. Most of time you get a veil where the opamp puts its own color on the sound and if there was clarity, it is now hidden in the veil/coloring.   The old 5532D is really clear, the standard for years.   LME49860NA is fairly clear while it...

Speaking of ATH-AD500x, I have the ATH-T500 (closed), the headphones actually have punching base, the 53mm drivers are also angled. Not a bad entry level closed back headphone. Handles like cheap plastic and the cups pivot 180 degrees so seems to rattle around as you put them on but once in...

Old TL082CN handles bass well (it's dual channel). 8066AR handles bass even better (single channel, needs an adapter, eBay has them already mounted). LT1028ACN8 for the output (filter?) socket will enhance any opamp before it (requires an adapter and a lot of room since it is side-by-side usually).

Amazon doesn't write the descriptions of products shown for sale, sellers do. One item might have four listings with various descriptions of the same product because four different sellers (manufacturer or not) wrote the wording for each page.   Important to do your own research from...

See things are kinda quiet around here so I can only guess that most have discovered Amps and DACs make headphone listening a joy. Most complaints go away when details are bought out with the proper equipment. From there it is a matter of preference in equipment and headphones.   Try this...

Too bad about not being able to get a decent DAC in a portable (Even so called high end desktop computers cards always sound a bit dark to me no matter which supporting opamps you choose, because the DAC is not feeding a decent signal to the opamps or has its own varied version of the signal or...

Here is some older discussions at DIY about this opamp lineup which I guess includes can variations. Seems the 4562 is a bit temperamental and could suffer from oscillations in the wrong environment which I am trying to avoid like with the 5532D and confirms the 49860 might be somewhat weak or...

So...I was working replacing the stock front channel JRC5532D opamp in a Klipsch 4.1 preamp after already finding and upgrading the stock sub output ST TL082CN opamp with an AD 8066AR and all replacing all 6 resistors on the little board with Nichicon 10uf 25 volt (aluminum audio grade, mainly...

Looks like current/update packaging for the OPA2107AP, no half moon indent, just an indented circle.   Mouser has them, kinda expensive. Here   eBay has the newer and older packaging. Here and Here For about $3.50 or $8.25 apiece, what could possibly go wrong? China is not totally backwards...

That is non-conductive cement holding the ceramic caps in place. I am wondering if changing the stock op-amps (the caps are jumped across some of the op-amps legs) to a more recent design that newer op-amps wouldn't need the caps at all??

I was working on a Klipsch 4.1 control pod (there are two models, the older V2.400 has a different layout). I have (3) 4.1 systems that needed certain upgrades due to overheating, some resistors, a zener and sometimes capacitors on the sub panel but this is first time a control pod has given me...

Sure these mini platforms for audio production vary. A DAC surrounded by a bunch of cheap capacitors is not going to sound all that great. But none the less swapping different opamps will still change the sound output on whatever platform you are using.. It is getting to be a software...
