Bluetooth Tube Amplifier Stereo Receiver - 600W Home Audio Desktop Stereo Vacuum Tube Power Amplifier Receiver w/ 2 Vacuum Tubes, AUX/MP3/Microphone Inputs, Pure Copper Speaker Output - PVTA20

Excellent. Very solidly built. The controls are smooth and have great feel. I like that they have a little acrylic cover over the tubes to protect them. Very surprising output, even into my large floor standing speakers. Warm sound, but dynamic too. I love this thing. I’m using these to build Bluetooth speakers out of vintage stuff like makeup cases. I would love it if they had female threaded holes on the bottom for mounting. Would make me job easier and could be used for other things like mounting to a wall or whatever. This photo is before I put the CNC machined clear plastic cover on. I’m also using their 4.5” speakers. Unbelievable output for that size. Fills the room. My patrons and customers love them. Pyle has this down I think.

Amazing tube sound from a very affordable amp. As you know, the price of audiophile gear can be a real budget buster. This little amp is perfect for a small room. Bluetooth is a real plus and the range seems fine for my needs. I have yet to add a sub so I can't comment on the sub out feature. The 500 w rating is very optimistic and the interior fan is way too loud, but easily disabled. I have been going back in my library to listen to the difference over my old system and I'm liking what I hear.

I will start by saying I'm pretty impressed. I just needed something to operate on Bluetooth and to run my turntable in my home office. I decided to try this little tube amp out. I knew the power ratings were way off. But I only needed it to run a pair of Polk TSi 300 towers. If it did well enough with those I would try the sub out. You will need it to run about 100 or more hours to truly know what the tube voicings will be. That is the normal break in period. I placed the two Polk Audio speakers next to the unit to try it out and search for distortion (first pic). Highs were crisp and clear. Enough mid range power to push these little towers. Plenty of expected bass for these speakers. Not booming but clear and punchy as you expect from woofers of this ilk (mid range quality). There is a significant drop off in signal strength between the Bluetooth and line in for a turntable. This turntable does hav it's own pream also. Again, this was to be expected at this price point. The sound was beautiful though. Clear, pure analog the way it was intended to be listened to. This I was not expecting. So I added the 10" subwoofer, corrected the phase, set amp gain on Sub to 25% and the same with the dB range on the sub. Knowing this unit was underpowered for what these speakers can handle i didn't want the sub to drown the sound out. The blend was excellent. I split the speakers off to good stereo distances and place the sub properly in the corner (second pic). The sound produced was very natural. Not overly processed even with Bluetooth feeds. The production quality was excellent for various music types. There was no adjusting of audio needed for latency. Thank God because this unit doesn't allow that. Overall I was really impressed at the functionality of this for the price. Estimated power is closer to 30-50watts RMS. Perfect for my mini towers in a small office space. I would not use this in a large room. I definitely couldn't run my Martin Logans off of it but for a decent set of mid range speakers you get more than what you pay for.

I am very impressed with everything about this Stereo Receiver. It definitely punches above its weight, and with its continued faithful service, I'll be a PYLE audiophile! (Something that passed my notice when I was looking for a home stereo & saw this one is that it has "EQ" functions {6} that do a nice job of adjusting the highs, midrange & bass with presets. I don't think that this is programmable{adjustable}, but I'd like to be wrong!) All in all, a very good buy, one I would repeat.

This seems like a great amp, I bought a “like new” open box unit from Amazon at a slight discount, and the packaging and physical quality of the amplifier are great! However Amazon clearly does not verify the condition of their open box returns, as it seemed like new until powered on and the power cycles off and on continuously every second with a loud pop. Of course there are no support options, and I waited a week for this open box amp to deliver instead of buying new for next-day delivery. Don’t make the mistake I did and trust Amazon’s “like new” condition of an open box item!

This integrated amp can work well, with a slight modification. I gave it two stars because consumers should not have to be expected to make this modification. Also, even if you were to return it, a different unit cannot be guaranteed to to do anything differently. I m talking about the fan noise. It was a nice effort to put a fan in because heat is a killer to electronics. However, the fan sounds like a turbo fan. For it being so small it s shocking how loud it is. So instead of returning it, i decided to modify the unit by disabling the fan. Here s how to do it: 1. Unplug unit. 2. Take the front fascia off by unscrewing the screws on top. 3. Once off, pull the fascia away. 4. Look inside- you can now see the fan clearly to the left, along with the red and black wires that connect into it. 5. Take scissors and cut both wires. 6. Take the red wire and move it onto the plastic fan housing. 7. Put the front fascia back on and enjoy the music. Regarding sound, the tubes need about 100 hours to break in to begin sounding good. Initially the sound was sterile and the sound stage small. I added one star because after break in it sounds very good, with the sound relaxing and the sound stage expanding. I have these running on paradigm signature s1 v1, biwired, about nine feet apart. The remote works well and is a nice addition, where the competition does not offer a remote. Five stars if the fan issue would get resolved.

For that money-Good sound. Easy installation Great quality

I really wanted to like this little unit. At first I was pleased, good sound, power and cool design. I did notice like so many other people said that the cooling fan was a little loud. I was ok with it as it wasnt terrible but certainly noticeable. Nearly 1 year later, the fan started making a horrible noise. Really loud and not bearable at all. I started a claim with Pyle, only to find out they will repair it within the year warranty however I have to pay shipping both ways. No promise either that the repair will be good or how long the repair is guaranteed. I feel like at this point I am just out the money as shipping will cost about half as much as a new replacement. Totally ripped off. Avoid this company. They do not truly support their products.
