ah well, I'm not really looking after a dark sound....and that'll be a waste of browndog adapters, considering I'll always think that there's a higher grade

anyway, so far I loved the LT1358IN8....maybe the LT1057ACN8/LT1355CN8 will change my mind, but I think it fulfilled all my needs

Jim Williams also praised the LME49722 here : rme adi-8 qs op-amps [photos] - Gearslutz.com

I wonder what parts Rupert Neve would like

 

[ROBSCIX]

The 2132 and 2134 are common generic audio opamps that have been used for a long time.

 

[SpudHarris]

Yeah, they sound like it too

so anyhoooo, based upon the earlier post I decided to try them both as I have loads lay around from when I used to sell cmoys. Now I know why they are lay around and not in my heavy rotation box, man they are pants.......

I wanna hear the OPA132UA... as it was said (on Audio Asylum, sure not here) to be an improved revision of the original OPA2132.

UA series is the SOIC equivalent of the PA series, applies to the U and P series respectively.

wow -- i didn;t even know that about myself-- having never been called a 'handy craftsman' before. not sure i ever referred to opamps as 'hoochie mamas' either -- but as an inveterate punster I am sure it has something to do with the leg-bending. what next, I'll start using emoticons!

on a more serious note, i think power supply considerations, beyond operating voltage and adequate current have a lot to do with the results people are getting/will get from various opamps. the has in my stx very much benefit from the outboard choke-filter linear psu i built. i just got a riser board, so i can use a pci card in a pci-e slot,-- which comes with a 4-pin molex to supply power -- i'm gonna use it for my re-capped prodigy hd2 which has been thru several opamps, and is sounding very good through my diy headphone amp and denon 7000s.

I would really like to try out the ADA4898-1, though no dual version is available yet....

According to JW, ADA4898-1 is much better than LME49722MA - it has better low end depth and extension, much better top end details. He also finds AD8599 to sound soft with transients, less bass and top end extension than the ADA4898-1.

 

[Pluto2]

So, according to a product manager at Analog, the ADA4898-2 is still in development stage (need some design changes), so it is hard to finalize the release schedule. The earliest possible release date will be in 1Q2010......fyi

 

[majkel]

So why would the UA improve over the PA? Did guys from Audio Asylum sleep well last year?

The ADA4898-1 seems to be the direct competitor to the OPA211. And now I know for sure - the OPA228P is what I like and the OPA211 is what is true but some recordings suffer from the OPA228P coloration and sound corruption. I prefer to stay calm because of hearing what I should hear, so let's get used to the OPA211... again, after a long break.

 

[majkel]

Ok, now it's clear to me. I can say for sure that the OPA2132PA was a little bit better than the OPA2134PA but the OPA2132P is a resonable step forward. However I still preferred the OPA2228P to them.

 

[majkel]

OK, so you have numbers 1 and 2. In the OPA211 the 2 is preceding the two 1's. In the LT1122 two 1's precede the pair of 2's. Which number configuration is more optimal?

I owned the AD8599 and "soft transient" is the last thing I would say about this chip. I compared them to the AD797 one day and the AD797 sounded more analog, darker and smoother, with better soundstage extension. So I stopped to buy this fragile chips - they like to blow when plugged to a supplied socket.

Computer = 666. The numbers tell all!

Look at the price. I'm not denying that the OPA2211 will sound better overall, even without some of the sophisticated midrange character of the OPA2132P. I'm also not denying that 2x OPA827 have about the same sophisticated midrange of the OPA2132P, but a perceivably higher level of resolution. But for a dual DIP opamp... the OPA2132P is my current favorite with the LT1358.

If it makes me feel good?

Suggesting these opamps are generic is not putting down their quality by any means. The suggestion to me means they are used in a great deal of audio equipment because they are decent enough units.
Also, don't use price as any indicator of quality...

I have both the AD8599 -just built that one haven't had much time to test. I also have a AD797.

The 8599 seem to be recommended a great deal when speaking about AD opamps.
I guess by your posting that you prefer the AD797 to the 8599?
Do you have any opinions on AD8620 or 8610?
