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?

 I see you have, or are considering sending back the PrimaLuna. If you haven’t already, I recommend you don’t - at least not until you give the KT120 or KT150 tubes a shot. Will cost you about $200.00, but from experience I can tell you, that with demanding speakers, they will shine far and above the stock EL34s. While the EL34s can be magic with very efficient speakers, they fall short with even slightly inefficient speakers.
+1 @ hardens "I recently rolled in a set of KT120 power tubes and noticed more detail from lows to highs and more power and weight in the bass".
I am driving my quite challenging Maggie 1.7s with a Rogue Cronus Mag. II, running Tung-Sol KT-120 tubes and it has no problem driving them to any volume I care to listen to and the resolution, detail and stage is incredible.
I think you owe it to yourself and your very nice Robson speakers to give it a shot.....Jim
