The 2134 is a dual and the others are single OpAmps you would need 2 of each on an adapter to replace the 2134



That's why you only hear it in one channel.

Hope that helps.

That makes sense. Thanks, I knew something was really wrong here, and I suspected it was me being a total noob on this kinda stuff.
 
So if I buy one of those adapters it should work even on my motherboard?

 

[SpudHarris]

Indeed.

You need a single to dual DIP adapter. E-bay is your best bet.

By the way the two OpAmps you chose are great. The 627 is an all time favourite within the audiophile community and the 843 is a very aggressive (fast powerful) sounding OpAmp. As long as you bought them from reputable sellers, I am sure you will enjoy both.

Look like fakes to me, the logo is all messed up and the ink is too white.

refer this picture of MUSE01 fake is left, genuine right...


Those photo where taken by me about a month ago when I received 12x MUSES01 I purchased from Japanese online store. Cost was $46AUD each including shipping.
Here are some better photo and the unique package they came in.

Those are the genuine ones, then?

Yep
 
There's only three authorized resellers I know that sells genuine MUSES opamps besides mouser and digikey (Who are both too expensive). I emailed NJR them self to confirm.

I ordered my 12 MUSES01 from http://akizukidenshi.com/. The site doesn't support english, fully japanese only.

I am currently using OPA211ID*2 converted to dual op amp [DIP-8 package, dual channel op amp] so it is actually 6 x OPA211ID total. I think it sounds warm and deep.

Or any better suggestion other than LT1352 for filters?

BTW, any opamp has interesting quality for mid and bass?

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).

Thanks for replying to my old questions.
Have been using ada4627 and opa827 in the active crossover...havent done any rolling since then.....
Not sure I could hear much difference. There was a difference when I swapped the opa2124 with lm4562 though..

 

[razzz42]

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 enhances the vocal range.
 
LME 49990 is a very good all around sound opamp usually found in consumer DVD players where they bothered to design and build around the opamp.

Hi SpudHarris...
 
Saw your excellent collections of op Amps on a previous post...
 
I just tried the LT1028ACN8, which I'm complete in love with
 
Have you tried this, and If so, do you have some suggestion for
improvements if you just like LT1028ACN8...
 
/Thanks Michael.

The 5532D must be a lot different from the NE5532AP I tried in my iBasso PB2.

49860 is uber hi-fi.  It is more than "fairly clear". 

 

[dwayniac]

I am trying OpAmp rolling for first time. I put a 2134 in a Audinst AMP-HP and I give it slight edge over the stock OpAmp.
