I had a Primaluna Dialogue HP with KT150's and Nos Amperex and Tungsgram tubes for a few years. The Line Magnetic 805ia with stock tubes killed it. I didn’t even need to A/B them. The HP is powerful, but the Line Magnetic, at half the rated power, is more powerful. The biggest difference is of course the sound. The Primaluna was detailed and surgically precise, but metallic, cold, and unrefined. The Line Magnetic is warm, full, rounded and the sound just blooms. It’s the difference between florescent lighting of the office and the softer warmer lighting of a home. Mind you I listen to classical and acoustic jazz, the Primaluna might be what you are looking for if into pop or rock music.
