Have had my Line Magnetic for 3 weeks now. Prior to purchase, I auditioned a primaluna evo 400 and a Naim supernait 2 in my home . I have to say, neither of them was a match for the LM. I mainly stream music thru a cambridge 851N. Speakers are new Tannoy Cheviot's. I replaced stock tubes with a pair of Brimar CV4003's and NOS Tungsram ECC83. Presently researching power tubes. Considering Gold Lion ,Psvane and Shuguang. Any recommendations?
