Op-Amps: Burson V5/V6 – AD797BRZ / ES9038Pro with Burson V5 / Gustard H-10 with V6

so, 😉
after i´ve re-checked my Op-Amp-“collection” 😉 (in testing them on an ES9038Q2M) and reading a lot of op-amp reviews again, i´ve ordered a few days ago some AD797BR(Z) (as described in some posts before)..

The “B“-line has a stricter factory-selection/-fabrication and is mainly considered as the best AD797 for audio..
by that, curiously, i got the most the site-/page-visits here op-amp-wise, means the main interest is also in the op-amp-section/part/reviews..
so i can/will hopefully test them in a few weeks and the next step (op-amp-wise) would be the “Burson V5/-6″-line..

was also clear, as said in the earliest posts..but they cost around 40-50$ (pair)..
(the third set of pictures here are some Burson V5 on an ES9038Pro->https://hallmanlabs.com/2018/01/04/pictures-of-es9038pro-dac-w-burson-audio-v5-opa-and-orange-amplifications-discrete-design/)

some good toroidal transformer (+-15V) cost also about 30-40$ (min.) and so i/u have to check out which will bring the best “tone/sound”-enhancement (or both of course)..

(Link-Aliexpress or from Audiophonics or something)
“Webcontrol”-ESP32-wise its still in development but primary i think i want now to search for the right case, transformer..
many greets from here for now 😉
