  • Very Interresting Earphone Amplifier

    posted by cabuch on 19:17:34 G6T 14/06/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: This tube amplifier is very beatifull when power on. When the tube amplifier is on there are a blue and red colour leds that make a beatifull effect together with the tube filament. The sound quality is good and the volume gain is adequate.

    Cons: The packet arrived very damaged to me. The Volume potenciometer was broken in the way until here. I think the package should be more resistant.

    Other: So, Today I am looking for a original potenciometer to fix the amplifier. After all it is pretty cool buy.

  • Great Tube Intro...

    posted by wampyz on 09:55:43 G5T 08/05/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: inexpensive introductory tube amplifier... nice warmer tube amp sound with a wider soundstage... small footprint... good easy-access construction...

    Cons: need to supply your own power supply... 24V 1A minimum... runs hot like other tube amps... partial side shields covering the two mosfet heatsinks right at the outer edge of the board would've been nice but that would interfere with the passive cooling...

    Other: make sure you add an RF choke to your power supply (if it doesn't have one already) and you might want to consider upgrading the stock IRF630 mosfets to the 510 or 530 series to get back some of the higher audio frequencies...

  • A nice headphone amplifier

    Pros: The quality is good, it works with 24 V dc. The low voltage makes it safe in use by anyone. The audio quality is good. The is a lot of white noise and the distortion is not the best but this is tube (valve) sound more or less. The sound is sweeter than the sound produced by semiconductors but this is not the best for all kind of music listening. For colored modern music with higher bass and treble, semiconductor amplifiers with low distortion and noise, sound better. It is always a personal matter of course. The amplifier is a class-A type.

    Cons: No proper packaging. It arrived packed in the standard babble type envelope. In my case, the volume potentiometer and the transparent up and lower covers were broken in the shipping process. I had to replace them at an extra cost.

    Other: For its price is a nice piece. I advice the purchase of it especially if you want to know how a tube sound sounds like :-). I have a recommendation to DX packaging department, "do better packaging that will offer better protection to sensitive items like this".

    Pros: it is the cheap and powerful a solution for the vacuum tube ampifier freaks. it works well and have also very nice look. you can use it for listen harnonic music and decoration

    Cons: quality is not perfect but good. Electronic board can be blue like the same color of the vacuum tube color.

    Other: it will give you a satisfaction if you have bored of full technology and looking retro, pure an amplifier.

  • Good But not quite there

    posted by RecyclerMan on 18:03:38 G10T 10/10/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Cheep valve head phone amp! It is actually very good. What does it do? Well it made the music sing out! In a way I was not expecting. When using good headphones I was hearing stuff never heard in my music! It was way better than expected!

    Cons: !!!HOT!!!! it runs very hot the output stage looks to be Fet based and the heat sinks are not up to there job Heat kills Silicon like nothing else. So am now looking in to beefing up the heat sinks so it don’t kill its self! The second big got ya was when using the 3mm ring tip sleeve connector it swaps left and right. It could do with some feet on the bottom of the unit as there is just some brass hex rod for feet and it does slip around! The packing left a lot to be desired but it survived the shipping with out problems! Not rely a con but unit needs to warm up to actually work properly that is the valve and before that it relay sounds odd we are only talking about 30 to 40 seconds but hang on did not valves need to warm up any way?

    Other: Cheep Cheerful would buy again. used sku100298 to power it, the hard ware to box and connect it cost more than the head phone amp and power supply. but less than a NZ bought power supply. From what I have read there is a lot of stuff that can be done to these to make them sound better. Could be a good way in to home brew electronics!

    Pros: When I received the shipment I was really looking forward to trying this pre amp. I practice the audio hobby for nearly forty years. I had never ventured into the world of tubes as owner, but as a listener and follower of his fame. I mean that the operation was as easy as unpack, connect the power supply, a CD player and a pair of headphones to start enjoying a very good sound. It really is remarkable the difference in sound. The full range of audio is heard on new planes. I also tried connecting it as a pre amp connected to a power amp without EQ, and the effect is the same. The same CD player sound changes from flat to another, full of nuances and colors.

    Cons: No one so far.

    Other: The power supply of 24V 2A also bought in DX. It's the right combination.
