Review: 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.
Review: Sweet! - I was a working musician for many years. I wanted an amp to couple with my Paradigm speakers. I purchased this model for $109 and it is worth every penny as it sounds great with plenty of power for my small room. The Paradigms are rated at 92 db and this hybrid amp does the trick. The build quality is excellent and having tone controls and a headphone output are a real plus. Having the valve preamp is nice as the sound is not clinical but warm. I have a pioneer SX-780 which is in great condition but I need to put new power packs into it plus a recapping. I will use the pioneer in my bedroom. The Rockville, for the money, cannot be beaten.

## Questions & Answers

**Q: Will I need a phono preamp with this unit to hook up my turntable?**
A: This unit has a tube preamplifier, and a solid state amplifier. However, it doesn’t have a built in phono stage (phono preamplifier). Unless your phono has a built in preamp (like an Audio Technica LP120 or similar), you will need a phono preamp if you want to play your vinyl. Phono preamps are fairly inexpensive in the quality range of this unit, so send Amazon another $20 and get your preamp. Don’t worry about Moving Coil (MC) or Moving Magnet (MM) cartridges. If you use an MC cartridge, you probably aren’t going to buy this amplifier.

**Q: Do the “blutubes” have blue leds in them? i really want a retro look and am trying to avoid any rgb. thanks!**
A: FYI: Most power amplifier vacuum tubes have a blue glow/hue of some kind. EL34 and 84 tend to contain this with the anode plate structure but is still present around the inside of the glass envelope. 6L6s and 6550s tend to have more of this glow around the glass. The orange glow some people are talking about is the heater filament and has the look of an Edison bulb but only a small part of this is visible as it is contained with the in internal structure of the vacuum tube assembly. This is much easier to see when the room is dark.

**Q: what class is the output amplifier?**
A: I needed to contact Rockville and I got this information from them - 

Rockville BluTube is a Class AB amplifier and uses 6N1 and 6P1J vacuum tubes.

**Q: What size is the headphone jack?**
A: I think 3.5 TRS means 3.5mm, which is the standard consumer size of 1/8 inch, used on most cell phones (except newer iPhones, stupid Apple) and portable music players.

### ⭐⭐⭐⭐ Rockville BluTube HYBRID Amplifier
*by A***R on February 18, 2021*

This PARTIAL tube unit from Rockville has some audiophiles scratching their heads! It sounds very good, easy to use but not as TUBE sonic as the high end ($1000+) Stereo Tube Amps on the market. Ive played my vinyls on this unit and my 100 watt rms Solid State Receiver and it's hard to hear that "warm tube" effect. However, I can say that I don't experience much listener fatigue as I do with the Solid State at medium volume levels. Playing CD's or Flac from the USB is a pleasure and sound very good! This unit serve my purpose for the price. The tube section only powers the pre-amp while solid state coupling provides the speaker power. The marketing is misleading because it says 70 Watts when really it only provides 25 watts at 8 ohms and 35 watts at 4 ohms. But the sound is loud and bright using my 8 ohm speakers which are not so efficient. The volume meter is puzzling as there is no reference. Also the tower behind the tubes is empty space, maybe just a design enhancement to make the unit appear larger than it really is! The versatility is obvious with inputs for USB, Coaxial/Optical and RCA, speaker and Sub outs and Bluetooth. Overall, I would recommend it to those audio lovers who like to listen to warm and sweet sounds at lower levels! Using headphones is a great treat, and using a pair of flat efficient speakers adds another listening dimension. It's basically a receiver with it's combined power/preamp/ and connections. My hearing today is not the same it was earlier in my life but I'm still able to enjoy better signal to noise and low THD which enhances the listening experience. Plus it looks very cool with it's blue halo of light!
