    Хорошие лампы. Звук хороший

    Perfect replacement tubes of for the Xduoo MT-604 that aren’t too expensive. Seem to have better midrange and overall better sound. They were packaged very safely and arrived pretty quick in under 2 weeks. I can overall recommend those tubes for replacements for the Xduoo MT-604.


  3. g***z

    Approached in principle and so well worked whether it became better until I understood subjective like a bass more became. But if that old lamps remain on stock


  4. F***s

    Excelente, el cambio de sonido respecto a los que vienen con el preampli es notorio


  5. F***i

    Increíble velocidad de entrega. Una semana desde el pedido en línea a la puerta de mi casa en Santiago de Chile. Las válvulas ajustan correctamente a mi Dilvpoetry tube t-6. El sonido se nota en principio con un poco más de cuerpo (bajos un poquito más profundos y un poco más aireado el sonido y amplitud en el sound stage ) respecto a las válvulas 6*1n originales. Veamos como van después de un tiempo de quemado pero me gusta el sonido de estas


  6. G***v

    There was detail. You can take it. Standard lamps gave “bubtenh some”


  7. J***s

    Excellent, I put them on a Kguss pre-amplifier and it sounds better than with the original tubes.

    Reached Istanbul in 10 days. The work came without breaking. I bought for Fosi P1. I got a little tough when I put on for 6 K4 with my own tubes. I may not be able to. 🙂 I put them in a little bit of trouble. I have a clear, clean and detailed music presentation. I haven’t tried my own original vacuum tubes. I can’t compare it for that reason. I recommend seller and product.


  13. A***s

    Good bulbs, I used it to upgrade the bulbs you bring from factory, improve soundstage, low frequencies and high frequencies, product and seller recommended!


  14. E***v

    Lamps are working, the difference in sound is almost invisible with stock lamps, the sound became more than the volume. Strange marking on the box, written by Italy.


  15. J***s

    El envío super rápido. Las válvulas funcionan bien
