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?

Trade it back in and try to get a used Primaluna Dialogue HP integrated then put in some KT88's or even better KT120's then hook the speakers to the 4 ohm taps and try it in triode mode for more detail, or ultralinear for a little brighter top end.

Please humor me: please check *carefully* the speaker cable connections on the back of the PrimaLuna. It is easy in poor lighting to mistake the 8ohm tap for the ground. Also check the connections on your speakers. Usually these things are something simple that was overlooked. Been there and done that!

You should not be surprised Kevin dealebig build up 
on an6 good vacuum tube amp  C core transformers are the best 
and used in the best amplifiers around the world Not toroidal 
transformers. They are used in Solid state amplifiers.
that's s red flag .  And on their preamp section cheap $15 Alps volume pot,  quality would have a resistive ladder or electronic  not a $15 alps pot silver Round cylinder  and made in communist China ,No Thanks.

I am delighted with the Quicksilver Integrated tube amplifier driving Focal Aria 906 speakers. Smooth and detailed both.
