Better and worse than I expected.
Not my first of this kind of device. I’m amazed by the size, and general design. Its one of the better looking vacuum tube amps I’ve used. I like all the controls, it feels amazing. Only time will tell if its built to last, but frankly best feeling device of this style I’ve owned. And I have some 60-70 year old stereo equipment that is pretty excellent.The sound is clean and solid.But the ambient hum on this unit is Particularly loud in my opinion.I have a 60 plus year old unit that has a more enjoyable hum to it, more of a low thrum. If you plan on using this to listen to quiet music you will certainly grow annoyed with the hum its just too upper mid in its sound.The VU meter on mine is not working the way you’d expect, I run this primarily on optical audio. Optical and Blu tooth are what I got it for… if its supposed to work with those what you need to do is MAX the output of the device sending signal to this and turn to volume on this amp WAY DOWN.The more I putz with it the more I like it. It has the output of a much larger vacuum amp… I guess if I was to complain about features, I’d have liked this to be capable of driving a center channel without any wire fu… but for a 2.1 it is glorious. Running it on a 2 left 2 right setup as I right this driving some vintage 50 year old pioneers and Sony throw back units from 20 ears ago. The hum will not endear it to you, at least the hum of my unit… if you want to listen to music below middle volume, its overpowering. Unless you place the unit far removed from where you’ll be listening to the music, and with a unit like this you want to be near it. The hum should add to the ambiance not detract. If you plan to be more than 6 ft from the unit when listening it sounds MUCH better, the tone lowers as the higher frequency sound from it is washed out. If you want to use this with a PC stereo system… its gonna be less than optimal.I like to blend white noise, so maybe I’ll find this meshes well with running water, etc. I will have it in a room with at a few aquariums.Testing it on salsa, 80’s rock, metal, country, classical, 90’s pop.This is not the final placement for my unit. Just how I have my PC setup currently, building a bigger work bench it will reside on and will be about 1-2 ft further from my head and likely improve my enthusiasm for it. A darn perfect and pure offering. How rare is it to see something without too much feature creep these days? Very essentially what it is.EDIT:After messing with this thing for last couple weeks I found leaving it on (not playing anything, just on with no input) brought down the tone of the hum from the tubes, making it much more enjoyable. If I turn it off and then back on a day later it is a higher pitched hum again. It is actually a very pleasant ambient thrum IMHO, and now is easily masked by low volume classical music.Given how much I like this in all other regards discerning this in a way to manage the amp has been great.I’d say I’m now 110% satisfied as I can absolutely get the experience I desired, and far exceed my expectations for the price tag.If you want a 2.1 vacuum tube amp that is modern in all the ways that matter and classic in all the ways that matter look no further. Particularly for the sticker price. Just need to see how these tubes hold up over time. I’m running OG tubes on my Magnavox amp that are 20 years older than me.EDIT:I’ve found that if you don’t mind leaving this thing on the sound of the vacum tubes deminishes to nothing. I leave it on non stop, I’ve not done a kilawat draw evaluation. I may and return to update this.But as it stands, unless this thing dies prematurely (and this is being measured against some 60 year old tube amps still going strong… ) Its kind of a no brainer recommendation, everyone should have one.

Really good for the price
I was really impressed with the sound. I ordered two other amplifiers from different companies and when you turn them up loud they got distorted. This one does not. You can turn it all the way up and it still sounds really good and clear. You can even parallel wire speakers together and have four of them and the commercial. When they say that the amplifier doesn’t hard clip, they’re telling the truth it doesn’t. I turned the full blast for about 10 minutes and it sounded really good and clear for $180. I’m really impressed. I ordered another tube amp for $400 and it was a class a b amplifier and the volume was Spike out of nowhere for no reason and then I ordered another amplifier. There was AB amplifiers and I spent $240 on it and the volume would get distorted when you turned it up. Not this one. This one’s a class d amplifier and it does not get distorted and the volumes up really good and clear and the treble blows my mind just how loud that treble can make it and the base is really good too. I got my hook TV hooked up to the optical Cable and it works great through the sound. The Bluetooth was great. Now my dislikes is. I wish that it was made out of better material. It’s definitely made with the cheapest material I believe on the market. It’s a plastic. It’s up some kind of cheap aluminum or metal on the top of the tubes are and then that little box on top with the air. Ventilates is just cheap plastic too. It’s basically 50% plastic and 50% metal or aluminum, but as it the blue shining through the tubes, it shines bright. I will give it that it shines very bright and the blue shines bright through the front of it. I don’t really care about that but my wife loves it so I definitely highly recommend it but I’m going to be up front. I’ve only had it for about 48 hours and I’ll give another update after about 30 days. But thus far, yeah it sounds better with most amplifiers sound to $500. I promise you that so far it’s not the loudest in the world at eight ohms it’s only 25 watts and at 4 ohms is 35 Watts and I’m going to say it’s every bit of it. I don’t think they’re exaggerating

Great… except for two things lacking.
I’ve had this amplifier for only a couple of days, but it works very well with my 4 speakers and, of course, because this is a company that knows some people actually like to fine tune the music they listen to, the treble and bass adjustment brings out the best in my speakers. The USB for my many collections of music on flash drives (something too often ignored by most manufactures) works well with the ability to go back to previous songs or forward. My television audio comes through perfectly and each source is easily accessible with a toggle switch. The big downside is no remote control! Really? So, I have to walk over to the amp each time one song maybe too loud or I want to adjust the bass or treble. How can a company be so otherwise thoughtful and not include something so basic? It also would have been complete with an FM tuner. With the remote, I’d have given it 5 stars. Rockwell does offer another amp with all these features, including FM and a remote, but the reviews kept me away. I’m glad to have this BluTube amp (I don’t use bluetooth, only wires) which also looks pretty cool and very different.

En términos generales bien aún no noto la diferencia por la parte preamplificada de los tubos porque no es puramente de tubos si no tiene dos pases la pre con los tubos y la amplificada que es digital. No encuentro tubos para hacerle un uograde a algunos de mejor calidad y con ello mejorar el sonido. Lo tengo conectado a dos bocinas Kenwood y un subwoofer pero quiero una klipsh de alta eficiencia mínimo 90db de sencibilidad. Lo uso con una salida óptica doble una a la PC y otra a la pantalla y la verdad ni llegó a la mitad del volumen para un espacio de 10 o 15 mts cuadrados le compré garantía extendida pues la marca no es muy conocida.16/01/2021Antes que nada todo ha funcionado perfectamente USB permite reproducir todos los formatos incluso de alta calidad como FLAC sin problema solo que no tienes mucho control si tienes varias carpetas ya que reproduce de una forma lineal.Le hice upgrade a unas bocinas Klipsch y son la pareja perfecta los tubos originales se usaron por más de 20 horas permitiendo que se quemen en su totalidad y se asienten muy complacido por la calidad de audio y potencia.El día de hoy llegaron unos reemplazos de tubos que la única opción que encontré de mejor calidad fue en un sitio de Inglaterra fue algo laborioso investigar que opciones de tubo se podrían reemplazar ya que las nomenclaturas de los tubos chinos no son idénticas a las de otros países.Aquí quiero resaltar que SI se puede haber upgrade de manera segura sabiendo que reemplazo puede llevar.Los tubos que reemplazo son:Pequeños la sección preamplificador 6N1PPares comprobados y equivalentes modelo 1968 grado militar ruso alta duración igual más de 5 mil horas, con un raro contenido mineral para mejorar los harmonicos. La misma aleación de nikel platino para los pines y oro en las rejillas. Más amortiguadores anti vibración estos son los aros plásticos que se ven en las imágenes.Estoy cambiando a 5 estrellas porque superó mis expectativasLargos o de potencia 6P1P-EVFueron rusos de grado militar con un tiempo de uso largo estimado en más de 5000 horas con pines de nikel platinado con rejillas de oroLos encontré en Inglaterra y tardaron casi dos meses en llegar pero lo valen.22/06/2023Estoy muy satisfecho con el equipo funciona de maravilla, le puse unas bocinas Klipsch mas eficientes y hace un mes compre un tornamesa Audio Technica el cual lo conecte y funciona de maravilla, solo noto que el nivel de volumen al que escucho los vinilos es mas alto que lo que envio por via optica en FLAC de 24 bits y 192000 Khz

Excelente equipo para iniciar la experimentación de equipos de válvulas (bulbos)Es de calidad optima costo/beneficio, mis comentarios en los siguientes rubros:Pro: Respuesta en frecuencia: muy buenoPro: Potencia: suficiente para bocinas, mas allá de monitores.Pro: Percepción: buen desempeño del efecto estéreo, sonido con claridad, input recomendada: AuxPro: diseño agradablePro: Bluetooth: da mayor flexibilidad para manejo de música usando servidores locales DLNA de músicaPro: Muy buenos bajos (bass) recomiendo poner subwoofer activoContra: Bluetooth; como ya es sabido el formato presenta limitantes de compresiónContra: su ecualizador de 2 bandas en treble, su respuesta la califico con 95Contra: aunque es un diseño chino híbrido, Rockville le pone un sello de marca muy bien logrado, espero que las válvulas o bulbos tengan durabilidad, no tengo referencia de su calidad o reemplazosContra: poca información en su manual, manual muy básico, no hay diagramas, en internet tampoco hay información de diseño, aun no lo abro (por validación de garantías) para evaluar su calidad y diseño interno.No lo recomiendo para home theater o TV, solo para evaluación de audioVisiten la pagina del fabricante rockville para detalles extrasConsiderando que lo puse a competir con mi poderoso Yamaha jajajaja no se quedo chico!!
