OPA827 is so damn nice.
Sounds more like an ADI chip than your typical BB, in ma 'pinion.

My proposal for dealing with such mods is to design a small external pcb, perhaps using one that might exist (which I do not know about), fixed close to the circuit and preferably using some input resistors.
Space should be available for power supply bypassing, and there should be pads to connect the power supply directly to this small board.
In the past they called such boards "piggyback", but I do not know why.
Even if it's not usually recommended to use sockets, I would put sockets on such boards to be able to experiment with different opamps. For that you would also need existing DIP to SMD adapters.
Finally had time to solder ADA4084-2ARZ in DIP-8 to SOIC-8 converter PCB and installed it into my modded Aune T1.Woah! Didn`t expect this out of OPA2228 used as HO opamp with Aune T1!
Very organic, natural and open sounding! And seems to deliver quite good amount of details.
Soundstage seems VERY open and airy but not sounding distant/laid-back with Siemens E88CC tube.
Bass & percussion hits hard, tight and clean. Vocals/mids seem very natural. Guitars full and weighty.
Seems 45mA per channel output does its work better than stock 38mA.
I`m suspecting this will be best for my ears out of NE5532P, AD8599ARZ, OPA1612AID but will let it "burn-in" for week and do more proper comparing along with ADA4084-2ARZ which I will receive in few days.
Initial impressions - OPA2228PA put a BIG smile on my face and head bangin! ;P
AD8066 (wider soundstage)Hey all!
I need your suggestions. I'm modding my XD-05 which sounds too 'warm' or 'thick' for my preference.
Im trying to make it sound more spacious, detailed and transparent. Swapping out the stock OPA1612 SMD.
What are your suggestions for an op-amp with spacious large soundstage, with good transparency & details? must be available in SOIC8, dual channel.
Pity I can try only AD8599 in my gear, would like to try those other two, especially AD8620 but it supports only max-dual power supply of 13V. Wonder if +-15V would kill it?AD8066 (wider soundstage)
AD8599 (more forward highs)
AD8620 (best transparency and details, most balanced of all)
