PrimaLuna Evo 200 underwhelming
Hi all, I wonder if someone can help or advise. I bought an ex. Display Primaluna Evo 200 a couple of weeks ago, mainly based on all the rave reviews and excellent comments on various forums. I must say, that vocals are terrific but overall, the sound seems muffled. There seems to be a hole where the mid range detail should be. I have tried the 4 and 8 ohm settings and there doesn’t seem a great deal of difference. I am using it with a Linn Genki CD player and Robson Acoustics Opulus speakers, also Vintage Tannoy Mercury speakers. I haven’t messed with the tubes because I have no idea how to do that. I so want this amplifier to sound beautiful but there is something missing. Can anyone help please?

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 https://upscaleaudio.com/products/primaluna-evo-200-tube-integrated-amp 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. |
