Questions and Answers
I get a 60 Hz hum that I verified with a Peterson tuner. Usually this is a ground issue. Thoughts?Enter an answer to this question.

Less than 50 bucks delivered, sounds WAY better, they answer all questions quickly and clearly!
great lil' amp as is but even better as a warm tube re-amp.
That said, remember that these tubes are for preamp only. the amplifier still uses a standard transistor output to run your speakers. Thus the "hybrid" title. These tubes are relatively small and put out very little heat so should last several years whether left on or off. The tie breaker here is probably that it will cost a bit for the power to leave them on 24/7/365.
I have the 50 watt model hooked up to a pair of Paradigm monitor 3's and although they are a little bit undersized, they really fill up my mid-size bedroom with barely close to 1/4 on the volume control knob setting.
If you are going to be using the amp in a living room or a wider area, then i would definitely suggest to get the 50 watt Monoprice. if a more bigger and robust sound is what you are trying to achieve..
ie: In the 1950s, the Recording Industry Association of America (RIAA) introduced an equalization standard that could be applied to the original audio as it was pressed into a record. This equalization, which continues to be used to this day, reduces low frequencies and boosts high frequencies, thereby compressing the audio so that more of it can fit on a record. During playback, the exact opposite function is performed through an RIAA preamp, resulting in the reproduction of the original audio.
Hope that helped.

PROS: Great sounding hybrid tube amp at this price point. Simple design and looks very cool. Bluetooth works well. Sturdy construction with a quality feel.
CONS: There is no mention of brand/country of origin for the tubes. My guess is China, but I could be wrong. For a hybrid unit like this, the tubes are absolutely essential. It would be helpful if Monoprice indicated the brand of tubes and sufficient information for tube replacement. Eventually the tubes will burn out and this may leave some some customer asking what to do next....

I also hooked them to a pair of floor standing Klipsch Reference Premiere RP-260F speakers and the amp powered them to impressive levels will a great degree of detail and bass and smooth mids and highs... This also has a line output to hook up a sub, which I'll probably do in the future..I'll admit, I am a bit of a "tube-o-phile". I own an Audio Research Ref5SE and GS150 amp in my big system. Yes, this little guy does not come close to 30+K of gear, but it makes a fantastic small room or office system. And the look with the tubes is an attention getter. I love the black faceplate.......Highly recommended.

First sound stage in this combination is very nice.
The 50 watts is way more than enough for even party level listening
The sub out and Bluetooth connectivity is a real convenience benefit.
Be aware that once Bluetooth is connected, every time you walk in the room the system will announce that you are connected.
I use these Klipsch speakers as my rear speakers in a 5.1 home system. With this amp I can take these speakers anywhere and I have stereo music ready to go.
I have also driven my 20 year old Mission Argonauts 4 ohm tower speakers with this amp and was amazed, once again great soundstage and clarity.
Bottom line it just works

First of all, the item arrived three days earlier than expected. Unboxing was typical - the unit did not come double boxed but had the foam bumpers on each side to protect it while in transit. Everything was wrapped and there was that nice plastic film to rip off the shiny bits. I had it up and running in less than five minutes and that included the time it took to pair it to my phone.
Let's also explain that this is not a full tube amp. Only the pre-amp input section is tube based (ie; any sound coming in gets tube treatment before being amplified). The actual amp section is class AB according to the manual. They work very well together so do not be fooled. You are getting a really nice setup for very little coin in the audio world
Out of the box impressions are simply amazing. The sound is smooth as butter with slightly muted but, present highs. Rich and warm mids with good extension on the bottom. Right now, I just have it paired to my phone and I'm very impressed with it. I'll be adding a Yamaha WCX-50 pre-amp that will plug into the cd input which will allow for more flexibility as the pre-amp supports LAN streaming from a NAS or any of the internet radio services.
Currently, I have a Martin Logan Dynamo subwoofer connected to it but, it's really not needed if you have a nice pair of speakers (keeping in mind "nice" is subjective). I'm running Dynaudio X-14 bookshelf speakers and they sound really good with this amp. A subwoofer will fill out the lower frequencies for sure but, it's not absolutely needed. If you are on a budget, check out the Elac Debut B6. For someone on a tight budget, they would be a great speaker that would not require a subwoofer. Of course having a sub is going "complete" the sound stage.
I've listened to a few rocks songs (Nickelback, Puddle of Mudd, Rolling Stones) and some standards from Renee Olstead and Sara Gazarek. I was quite impressed with The Rolling Stones' "Can You Hear Me Knocking" and "Dead Flowers". The sound stage was broad and had plenty of depth. It handles all genres very well. What really blew me away was listening to Morgan James tribute to Nina Simone. This is a live recording with little bits of ambience and which are faithfully reproduced by this little amp. I was easily transported to Dizzy's where it was recorded. In between songs, I could hear the tinkling of wine glasses and silverware. The sound was precise, openly free and airy. The placement of each performer was well defined to the point I could picture where the drummer was, where the bass player was, where Morgan was standing when singing. It all pulled together to make a very enjoyable listening session.
So, where does the amp fall short? It's definitely lacking punch. It's rated at 53 watts/channel per manual specs but, it probably falls closer to 30 - 35 watts at 8 ohms. This is not a bad a thing because you get to hear music at nearly full volume without distorting. I can't really ding the amp too hard for lacking the punch because it does not really need it. Just know you are not going to supply music to the whole complex or next house party. For the money, you are getting high fidelity refinement on a beer budget.
Lastly, I was not provided any compensation for this review. It's is my honest opinion and I paid for this unit with my own money
PROS: Great price, good power, powers my Superzeros without any problem, sounds good with Bluetooth too.
CONS: No headphone jack

Before sent it back I plugged the amp into the same 120 VAC plug that my Bose unit was plugged into and the noise totally went away. Must have had some type of ground loop.
Playing Pandora via bluetooth from the phone works great.
Over all I'm very happy with the purchase.
