PrimaLuna Evo 200 underwhelming

@keeferdog Wow. You weren’t kidding (I didn’t think you were). Today I received and installed a set of 8 KT150s from TubeDepot and I am putting my PrimaLuna Dialogue Premium HP through its initial workout of a very big playlist via Roon/Qobuz. This is an entirely new amp! Where do I start? Compared to the stock EL34s, the soundstage is huge. Imaging is great. Bass and sub bass is big and tight. Everything is bigger and more forward. Highs on cymbals and high hats are discrete. It is just better in every way. And this is just on the initial listening session right out of their boxes! Before these KT150s I was thinking of selling this PrimaLuna. It was just ho-hum. Now? Unreal. This thing is going nowhere. Thanks for the tip on the KT150s. By the way, TubeDepot was great to work with and very responsive to my shipping concerns and everything worked out. I will let them know too. If any of you own a PL, check your manual. If you can use KT150s! It will revolutionize your amp. No kidding.

@kingbarbuda how is it in triode?
and ultra-linear?

 The tubes are EL34’s.

~~~~~~~~~~~~~~~~~~~~
My  favorite tube, as price is lower than the 88's, and as i am a  cheap scape right now, after WASTING< so sooo much cash in audio past 2 years,, EL34's are IMHO the best power tube
I've heard 120, 34.88, the 3 ,,add SET 250 tube,, they all sound near identiacl..

I did try the very popular Gold Lion KT88's and I did not like them


I had a  PL pre amp bouught used,, in the 1st few minutes I know it was not what I was looking for..

Yes it is made in the very same plant as my fav tube amplifier, CAYIN...
THey look close same build,, but for soem reason they do not sound the same.
I returned it and gave the guy a  gracious restock fee of 20% (I do this on all my returns).

Not saying all PL designs have issues,  just adding my 2 cents. 
It was a  older preamp model, still its my belief PL and Cayin sound different

I have an Primaluna EVO 100 intgrated with Bluesound node 2i, innuos mini Mk III. The sound is breathtaking

~~~~~~~~~~~~~~~~~~~~~~
Well goes to show, not all PL amps are equal, 

Cayin is consistently best sounding. 

- 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......
