Recommended for Primaluna

I rolled these in to my Primaluna EVO 400 to replace the stock EL34 which I had been listening to for a few months. The stock EL34’s have a sweet but very forward midrange, with fast bass albeit not a lot of body and weight, and a smooth top end that’s a little rolled off. The EH 6CA7’s have a much more balanced presentation top to bottom, really nice highs a touch more pronounced without harshness, midrange excellent though not as forward and sweet - a bit more matter of fact, and the bass has really impressed me, considerably more weight and fullness but very detailed. Really happy with these power tubes as an alternative to the stock el34’s and shopping with Evatco was pleasant and easy.
