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?
When I say discete, I mean opamps built from discrete components. Such as those from Audio-GD, Burson, ClassD..etc
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.
I was looking for a warmer sound, as these 49720 standard op-amps are a little lacky in that area.
Hopefully the analog sound becomes most favorable.
All i need now, is to find a decent place to get them on the cheap.
Yup, that's me...
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).
Are you sure?
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.
Where you able to get your hands on any of the E1 flavors?
I would like to read your comment/reviews.
P.S: I am waiting for Amazon to stock on the ZXR.
Yeap, he was one of the first Essence one reviewers :)
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.
