PrimaLuna Evo 200 underwhelming

There seems to be a hole where the mid range detail should b

~~~~~~~~~~~~~~~~~~~
You know
Thinking it over and visiting the EVO web site,, intergrated or pure amp??
Either. Both use all 12AU7’s in the front section.
Same as the PL Prologue linestage I had tested last year.

Just wondering,,,is if a all 100% 12AU7 pretube section, somehow misses that lil kick in the midrange??
Now I love 12AU7’s. as the most important tybe in a AX/AU circuit,,but seems possible leaving out the AX in the front,, somehow a AU just can’t add that punch to the mids..

Thing is, Cayin in the super duper linestage SC10 mark2, also employs 4 AU’s in the circuit, zero AX;’s.

I really wanted that linestage at one time,,opted for a 2000, well used Jadis DPL..

anyway,
thats the only thing I can figure out whats going on here,,as the build is stunning and impeccable, like all Spark China amps/linestage

NOTE::
PL employs takman Resistors, 
1st class, But I;'m guessing  REX carbon..
I don't like carbon, has to be REY's Metal for superior details and resolution.
The REX/Carbon are too smooth, prfect for jazz fans that adore  their overly warm sound,,which makes no sense to me, as 
warm + warm jazz recordings = 2X's warmth.
YUCKKKK
Try swapping out the Rex for Reys, and see what happens. 
Order from parts Connexion

Warm in the seanse of melding/meshing the midrange all together,, ultra smoothhhh, 
but then  cuts off the crystaliztion factor.
carbon offers a interesting image, no doubt.
But ultimately I opt for Metal. 
I think Takman offers best metal resistors. 
I also think once the Rex's are swaped to Rey's the quad of 12AU7
's will offer the best linestage circuit.
The AX = 100 amplificatio factor
AU= 20.
Honestly a  all AU linestage would work better in my system as I am now using high  sens WBers, and don't want that added push from the linesage's AX's in the circuit.
This would allow more gain control on the  vol pot.
The DPL had 2 AX's but my tech after modding with Takman Rey's , a  few weeks later,, suggested the circuit could swap out  one of the AX's fora  AU,,and it worked like a  charm, = superior performance,, so the other day,,i  attempted to swap out the  other AX for a  AU = no go, 
So based on this swap of  AX for a  AU, with superior results,,, leads me to believe AU's are a  superior tube for a  linestage circuit,. Which is why Cayin employs a  quad of 12AU7's. 
Smart. 

@holmz My comments above are all within ultralinear. I have not tried triode yet. But I certainly will. Thanks.

That amplifier allows switching on the fly… With the remote.


The Taksman resistors “being so sensitive” sounds snake oily,
They are used to limit currrent, and in dividing voltage.

But I know people that do not like the sounds that athodium plated connection gives, so maybe they are better at it.

@holmz I know. I just have not made the comparison yet. 

@kingbarbuda it was not subtle when I poked the buttons.
