1. El sesgo y la ganancia de dos tubos 6E2 se establecen mucho antes del envío, presta atención a las marcas de canales R/L en los tubos, no los insertes mal durante la instalación.
2. Conector de auriculares de 3,5 mm con prioridad, asegúrate de que los auriculares se hayan desconectado si quieres salida RCA.
3. Diseño de enchufe de tubo enchufable, conveniente para ser reemplazado por 6K4, EF93, 6BA6, W727, etc. para disfrutar del sonido de tubo de diferentes estilos.
4. T9 es un preamplificador no un amplificador de potencia, necesario para trabajar con amplificadores o altavoces activos.

I am that guy, the guy that buys ways too much stuff on Amazon, and never leaves a review. However, with this truly amazing preamp, I felt it was the least I could do. I had it within 48 hrs of ordering. Product packaging is very well constructed and secures the delicate tubes extremely well... And the sound... Oh my! ... I am truly gobsmacked. I previously was running a Rolls VP29, which I really loved. Solid sound. However, I've wanted to try that tube sound forever. I am absolutely blown away. I noticed an immediate upgrade to my system right out of the box...and from everything I've ever read, or heard, they will "break in" and the sound will get even better. Hard to believe!!

No audiophile, but this phono pre amp makes my vinyl sound so much better. I actually didn't think I needed but you know the hobby! Thought it sounded fine with the built in turntable preamp. Decided to give it a go, and glad I did. The music sounds more full and indepth. More warm and punchy. I listened to the same vinyl with it and without it, and boy there's a noticeable difference. I actually thought I left the turntable switch on phono instead of line when I disconnected the Douk because it was so weak!!! Didn't touch volume, left everything on usual settings. I said to myself man it sounds low and weak, must be on phono still!! It wasn't. I had it back on line like I had played all my records for the longest time. Right then I knew I needed a preamp and this Douk fit the bill perfectly.

I like the sound quality. It took a few hours to warm up/burn in the tubes. Sounds clear and warm. Not bad for the price

I like that this was easy top set up. I have it plugged in my Fisher RS-1052 receiver vis the aux port. I connected both my AR turntable and my computer external sound port. I really enjoy the sound difference, the controls on the front really give you flexibility in customizing the sound. Start out on lowest settings as this really pumps up bass and treble. The question of "does this really add that warm tube sound to your system", I have to say yes when you get it adjusted to that sweet spot - everyone is different. I am thoroughly enjoying it, I have owned this since August 2024, it is now Dec 2024. I use it everyday and it seems reliable and of good quality and I love the sound.
