= I know, you are a cool dude, as long as we are having fun with it.
Some here, not this thread, DIY itself, have there heads up there a$$es too much for my liking!!
okay, so are you an audiophile? I'd never admit that I am one 🙂 I'd sooner admit that I am a stoner that that 🙂
Luck I am a scrooge or lets say thrifty/meager, tight a$$ is too much in bad taste.

Dc servo doesnt sound with amplifier . OP Tl 072 or 411 are good servo only dc under 10+- mv.
For sound only discreate Op burson or dexa op are best, dexa danish are fantastic for Dac output
better and many tubes.
better and many tubes.
Dac dexa direct to input of slewmaster with volume control ,Dexa very low output impedance
with no harsch of sound from low bass to the upper end of frequency, it's wonderfull listen to.
Bass outstanding,

I had proven all Op in Dac output ,no one you can use,but Burson or Dexa are acceptable,all other's are only crap .
Dexa ,Burson .... Oh , boy (where do I start) ~ 🙄
Dexa - NewClassD Discrete OPAMPs
At least they are going smd. Module looks like BCxxx SMD in a symmetrical
array. HAH ! they show the ne5534 as the "villain" to replace right under
the overpriced modules. 🙄
Edit - Yes ! A "spooky" IC replacement.
Burson - DIYA advertiser , can't say much besides that I see the 2 CCS's.
It's a blameless , like a ne5534/TL072 - LTP VFA.
And it is "lavish" .... what ? Sounds (lavishly) "fluffy" to me.
They show pictures of how to replace the far superior OPAxxxx op-amp
in your CD player with the "lavish" modules. 😎
I should design some to make $$$. What an idea !!
Edit -
Op-amp Issues - according to Burson ...
Not designed with a focus on sound
Highly inconsistent in quality
Poorly construced and degrade the signal on all levels
Suffer significantly from EMI
-exactly what the larger size of the module would create (increase).
-IC junctions and matching would be more uniform than discretes could ever be.

I think Dexa are perfeckt for input in power amplifier, i agree about 5534 or TL072 not as signal.
The Dexa is the best of the 2 , but both are over-priced.
They are just mini spooky's and wolverines with low current/
low voltage operation.. nothing more - no "magic" ??

Even Burson are good i think, but Dexa very refined solution of his amp more of science with
his amplifier,
his amplifier,
Yes perhaps unnessary with your's amplifier as poweramp they work good,but with dac output
to power are very good,yes little overpriced i think,

I think not ordinary BC more special types from Japan or Zetex i don't now transistor ,better type
of transistor i think, he use.

So now we know, TL072 in absolutely fine for Slewmaster servos but maybe not the best for DACs or other completely unrelated related subjects.
Thanks. 😀
Thanks. 😀
Before he use of more linear transistor types with low re from Japan, but even type from Zetex.

I prefer even discrete transistor for aktive filter 12 or 18 db,not OP and discrete for Line amplifier.
