post #3796 of 4693

any love for OPA1662? Amazing low end and imaging in my set up. Not sure if you'd class it as tubey but I guess results will vary dependant on circuit. It's a must have in anyones collection either way.

Hi Mad Max,

If you have a set of LME 49720 or LME 49710 and have been listening to the ADA 4610-2brz can you swiched them to the LMEs and tell me what you think?  In my circuit I think the LME are more detailed in the microdynamic area and brings the midrange back into the sound stage.  The LME has resolution in the bass where the ADA 4610-2brz are wider in soundstage, more focus on voices and lack the ability to emphasize the micrdetails.

 

Looking foward in yours or anyone else that can conduct this experiment  smile.gif

LME49720 AD797B 4610-2BRZ ADA4627 LME49990 LME49850

 

LME49720 (Metal can) has more authority. More RAW if you can guess what I mean. 

Deeper bass. but the high is a bit sibilant and slighting piercing. 

 

AD4610-2BRZ is more polite. More Details, layering, seperation is clearly better. 

It is slightly smoother. 

 

LME49720 is better for Rock and Guitar, 4610 is better for Classical

 

Tested by just changing the OP-AMP nothing else change. Volume un touch.

I'm still using them on my cd player.L3000.gifAlso, i used OPA1662 and BUF634 as on The Wire Headphones Amp set-up, the sound is so good

Nice one Tommy...

 

I'm using them still in my PB-2 and P4, I think the low end is the most impressive I have heard. Not boomy, just tight and deep, man I love these opamps.

Hi everyone


I read this forum for a long time, I have never post anything because my english is so poor...
Thank you for all the informations.

I have use the 4562 for a long time (it is the same as the lme49720).
the metal can is better, I confirm.

The details are very good, but it lack of life, the high are pro-eminent and the voices are not so good, it's boring after a long time.
They have to be combined with more 'musical' opa or amp to be good.
All the LME have the same kind of defaults, if you like this kind of sound you should tried:
- LME49725, LME49722 I prefer them over the 49720, they are even more detailed,
- LME49713, is more natural, very fast and powerful, but it can oscillate, (cfa amp / 1.2kR feedback resistor necessary) it can be a good headphone amp (for high efficiency headphone)
- LME49990 is the more detailed, it can be harsh, but I like it.

The 4610 have the same kind of sound than 4627, 827 and 627, it's coloured like a valve amp !
The 4610 and 4627 are the kind of this type of sound, they are detailed, with a large scene, it's not me cup of tea, but sometime it can be good...


My preferred are : opa2211 (highs a little metallics), ada797 (grainy sound), op1662 (equilibrate, with a good energy, but not very detailed), opa1612 (too sweet; forgiving, and a good "foot tape factor").

And for the Jfet (it's less good) : opa2142, opa1642 (the highs are not naturals), ada4610, ada8620....


Good listening

Yes, but did you compare the price difference?(its "under $10-20" and "$160" /pair), For my opinion n taste, if i can do opamp ic rolling for under $20/pair, i'll do it for my $200 cd player but for $160/ pair burson opamp, hell no rolleyes.gif

Otherwise, i still using my Goldmund stuff (36 cd player,12 DAC, 22 pre-amp, and a pair 29.4 amp), its away better sound than bursonpopcorn.gif

hi

Burson are coloured, characteristics are bad (distortion ...), some guy like this, but not me.
Definition is bad, it's veiled, all the instruments have the same sound, after a long time it's boring.

You can try it, it's a lot of money but you can like it.

depend on your taste n you need to roll it yourself, these are the choice:

- LME49990 is neutral n nice

- LT1122 is more microdetails n crips

- OPA1662 is so sweet on mids n vocals, nice tight bass

That's exactly right!!

 

Personally I also like OPA602BP (CM in my EF-5), neutral but nice detail. kind of between the 49990 and LT1122. Also, I like ADA4610-2-BRZ, these are very nice indeed and great match with my musical taste (Shpongle - Younger Brother - Aes Dana - Asura - Sergio Walgood - Astropilot etc...etc...)

Actually, 4610 just sucks at microdynamics versus all the others I have, lol!  I wonder why.  I somehow overlooked this.

So you actually did what I requested on a previous post and discovered what I found or are you just joking???confused_face_2.gif

The microdetails are somewhat compressed and not so emphasis compared to the LME 49720.  Im going to listen to these for a while and then change to the ADA 4627-1brz

post #3810 of 4693

Not microdetails, the dynamics.  I do not hear a difference in microdetail retrieval.

ADA4627 also beats 4610 with dynamics.
