Default lme49713 vs opa627 vs AD815 vs opa2134 vs opa1612 vs opa2836

hi i wanted to know if anybody have used the above opamps. The new national opamps are also there with extreme slew rate of 1900v/usec just like AD815. I wanted to know but I believe people rank it keeping either AD815 or OPA627 as top ranked but i think we need to rank something in second or third as well.. any opinions if tried any of the new opamps...

i tryed lme49722 opa2134 and opa1612 ,

--..the best sounding is OPA1612 ,not for driving headphones -low output current drive ,3ma current consumption

---then opa2134 the best all around as preamplifier it can be used at high gain 6-10 times,very good sounding and Musical,good for biassing in class A.

--lme49722 lme4562 lm4562 opamp is very good sound ,higher ratings than opa2134 -but not as warm and musical (recommend 2134 for driving amps) high current drive,enough for headphones but consumes over 5ma,in my flac player battery lasts 5 hours with it,i have to change it to <1ma. ---Recommend 49722 for surround home cinema systems -replace in Asus Xonar cards and you have High fidelity home cinema +7.1 tripath and good to go >110Db SNR needed
Also good for DAC opamp I/V but even LF353 is good there

---Opa2836 2835,its hard to find ,HIGHEST specs -maybe has drawbacks ,like some frequency's can be isolated (no soundplus or else) -the best for driving headphones as it takes only 0.75mA ,amazing isn't it ? -didnt tryed it yet

I have just recently obtained most of the OPAMP's you have mentioned for testing but haven't had the time to get to them yet.

Although this has been discussed in the past I think that this can be an interesting thread with some updated and straight forward opinions.

One of the newest OPAMP's that is out is the OPA1664 and OPA1662 from TI.
Also there is the LME49860 with an astonishing low THD of .00003%!!!
Just to name a few.

I have these but I haven't tried them yet, and it would interesting to hear what others have to say about them as well.

Thanks !!!
