Bueno, Bonito y Barato!
Desde que decidí armar configuraciones de equipos con conexiones balanceadas XLR, estaba en busca de un nuevo preamplificador de tubos, ya cuento con algunos como Aiyima T1pro, T6 pro ambos en RCA y Douk Audio H8 XLR balanceado! Me llamo la atención que Douk Audio T8 pro sea Equalizador y preamplificador a la vez, con tubos, y que además tenga conexiones equilibradas, por este precio? Honestamente no pensé que fuera a ofrecer más que los que ya tengo, pero bueno, démosle una oportunidad y probemos, que no se pierde nada! Cuando llegó lo puse en el estante de mis equipos, y al día siguiente me entró curiosidad por ponerlo a prueba! Normalmente mi configuración empieza en mi fuente de audio, que es mi Smartphone, conectado a un DAC, en este caso está el Fosi Audio Zd3, al centro un pream. De tubos, ahora entro T8 pro, y en seguida algunos de mis Receptores en este caso quedó ZA3 de Fosi, también probé el nuevo Aiyima A20. Por principio de cuentas fue una grata sorpresa el nuevo miembro de la configuración central, el Douk T8pro, y a medida que encontré su balance a mí gusto de sus frecuencias más me fue gustando! Y aún hay más! En la medida que fue tomando temperatura, más detallado y calidez mostró en cada canción que escuchaba! La verdad quedé encantado con T8 pro! Es una ganga! Tomando en cuenta que sus tubos son el 50% del precio total! El otro 50% es la máquina! Douk Audio! Si en un futuro decides actualizar al T8 pro que sea para mejorarlo! Sino, déjalo así, que así está perfecto! Ahora T8 pro paso a ser un titular indiscutible en mi configuración de audio! No lo piensen mucho en adquirirlo! Este chico está indiscutiblemente recomendado!

Fantastic Tube Pre-Amp for the price
I say it reviles the $1000 Schiit Freya+. I bought extra tubes to roll with including British MULLARD ECC 85's and Russian Voskhod Factory OTK1 6H1n-EB's ;o)

Fantastic EQ with well thought out center frequencies
I cannot say enough good things about this awesome tube EQ. First of all, I love the frequency centers - I wouldn't have minded if the 50Hz band was a little lower, say 40Hz or even 30Hz for those of us that have subs (the Schiit Lokius's lowest band starts at 20Hz), however the rest of the frequencies are fantastically placed, at key areas that often need to be adjusted (such as 16kHz, 120Hz, I also find 315Hz to be really useful). The knobs feel fantastic, with a grippy non slip surface & pots that have just the right amount of resistance and are tight with no slop. The volume knob also has detents every 5-10 degrees or so which feels great & the balance adjustment is also a welcome addition. Having never owned a tube pre before, I wasn't sure what to expect in regard to sound quality. For the most part, I found the tubes to sound adequate for the price, however I was able to get a better sound replacing the tubes with this pair that was recommended by another reviewer: https://www.amazon.com/dp/B08QG4ZC1V These tubes give a really open quality to the midrange & overall presentation, however so far both the stock tubes & these (unless it's an issue with the unit itself) have a side effect of rolling off the lowest octave of sub bass which is my only issue with this EQ. However, it isn't really noticeable on most speakers/headphones unless you have a sub that hits really low. Highly recommended!

A solid 4.5 star rating
I purchased this eq almost 2 years ago but had yet to hook it up until this past weekend. I am using it with balanced connections coming out of my Topping DAC and going into my Yamaha A-S501 amplifier. I decided to replace the stock tubes with some GE 5814A military grade tubes that I had laying around. The sound is very robust and the high end really gives my normally warm AR 2ax speakers a nice sparkle. I have the rest of the eq basically set flat. It doesn't take much tweaking to load up on the bass and mid section so I left them alone as they were already good to go. It did seem to give the mids a little more texture. Overall it's a nice little add on that is compact and does not introduce any noise in the chain. I'm glad I remembered I had purchased it and now after almost 2 years will put it to work.

Estuve apunto de devolverlo
Estuve a punto de devolverlo por qué no daba la suficiente salida para mí bocina amplificada, pero después de ver qué hay que subirle con un desarmador quedé maravillado del buen sonido. Yo lo compré para conectar un bajo electrico y sus frecuencias son muy buenas
