Was planing on getting three discrete 49720 for the buffer stages, but unsure if it would sound any different than two 49710HA's so i never waved the go flag.
Have you ever tried one?
Does it make that large of a difference?

I see, I thought my post was abit unclear.
As for you other question,typically, discretes have a warmer more "analog" type sound in comparison to some IC opamps.
I am planning on doing some experiements soon when I have what I need.
Edit, We cleared up some misinformation, there are no discrete LME49720 models out there.

The Audio-GD models, would be a good place to start. I will see if I can get my hands on an E1 and do some testing with some discretes over the weekend. I will let you know what I find when I am done.
But what I'm looking for there is the firmware to my CM6631A USB-to-SPDIF box due to Mac compatibility issue... No relation to the E1 (in fact the E1 works great with my Mac).
Anyway i just tried out the 49710 instead of the 49720 in lpf in combination with the ad797. Strangely it has less details, less soundstage and less smooth sound than the 49720ha so far.

I just took out my 10HA's and put them in I/V along with some AD797's in LFP, and i hear the opposite of what you hear, except for the smooth part. AD797 has a little more smoothness to them.
Took out the AD797's then added MUSES01's and clearly, the muses sounds better.
I don´t understand it either but they do sund very different. The 49720ha has also a special bright character, the 49710 does not have that. Maybe they need a little burn in. The seller mixed up my order for adapters, instead of 15x single soic to dual dip8 and 7x single to99 to dual dip 8 i recieved 9x single soic to dual dip8 and 18x single to99 to dual dip 8. Hopefully he well send me the missing adapters.
THe LME49710 is just a mono version of the 720, IMO, they are an improvment astypically running a dual mono amp in favor of a single dual offers improvements.
Perhaps there is something else at work here and/or everybody has their own tastes.

Yes this is why i am surprised that the difference is rather big. After some further listening i don´t think that the 49710 is worse, the biggest difference is that the 49720ha has analog style smooth highs (actually a bit too bright) while the 49710 is rather fast and more direct sounding and less bright.
Also seems like that the ad797br is not really stable in i/v with any combination, tried it in combination with 49720, 49710, opa827, opa 2132, opa 2107 in the lpf and it always made some oscillation noises. As bypassing caps i tried 100uF electrolytic and 220nF film capacitors but both didn´t make it entirely stable.
