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?

before I went off  buying new speakers I would try some tweeks.  The 3 tweeks that I saw the most significant improvement in my tube amp system was using:
#1-NPS enhancer on all the connections.  It makes no logical sense but this really improves sound more than any of my tweeks. Crazy…

#2- Qsa yellow fuse in the amp. Another crazy improvement defying logic. https://www.tweekgeek.com
#3- Tubes.  Vintage 12au7 preamp tubes make a big difference.  Rca blackplates, Rca cleartops, GE blackplates from 50’s-60’s are affordable, available and good place to start before getting into more exotic rarer tubes.  Switching to 6L6GC / 7581 is a good choice.  It’s a very musical tube with adequate power. Talk to Brent Jesse for advice.  http://www.audiotubes.com
Good luck with your improvement.
