PrimaLuna Evo 200 underwhelming

- at least not until you give the KT120 or KT150 tubes a shot.


~~~~~~~~~~~~~~~~~~~~~~~~~
My friend  lent me his Allan Organ monos, with KT120's, He says it is his fav tube.
Honestly I can't tell the dif from a 34,88,120, They all sound pretty much thev same..
What we all need to know is what
preamp tube
is he using.
Preamps tubes make a  huge ,,well lets say a  nice nuance dif.
I've done shootouts with 3 or 4 brands of pretubes.
Tele;'s always come out clean winner.
I am speaking of the AU's. and note,  the NEW Tele AU prices....sky rocketing,,.,,, word has gotten out......

I would try the KT150 tubes. The EL34 tubes will give you a fantastic midrange but not the extreme bass or highs.


~~~~~~~~~~~~~~~~~~~~~~~~~~
Even though I've not acutallu heard a  150,,I am saying your comment is snakeoil

THe 34,88,120's sound almost identical in my system, dif amps,.
The EL34 has  just as good bass, highs, as any other power tube
34=88=120
My friend who uses 120's says he did not care for the 150.
So tahts that.

Its the preamp slot that makes ALL the difference.

If a Tele in the pre slot does not help  out,,then we know  this amp  is not his cup of tea..
I will also add
Yes get rid of the chinese 34's. 
Try EH. again this might help.

I bought a  olde model PL preamp,,,and pluged  in  6 Tele.s 12AU7's , did not like the sound,, back it went.

I should say, after thinking about the 150, My friends vote does not count, Why?
If Jadis designs a  amp, specifically for the 150, you know its a  great power tube.
IMHO the 34 vs88 vs 120 vs150, good luck on a  blind test.
Even SET's sound very close to PP amps,
Minus the 300 B tube which was made for telephone companies back when.
Pre amp tubes make the dif, 
Wish to single out the Gold Lion 88's. I did not care for that sound. too mushy...

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

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.
