## Overview

The SMSL T2 Vacuum Tube Mini Stereo Headphone Amplifier combines cutting-edge technology with a sophisticated design, featuring low ground noise, high drive current, and a compact form factor. Its durable CNC aluminum construction and semi-set tube design ensure both safety and style, making it the perfect addition to any audiophile's setup.

## Description

FEATURES: Our T2 amp utilizes two 6J9 J-grade tubes and two NJM5532D tubes as core parts of the circuit. The 6J9 tubes amplify the voltage which increases the input signal. The current formed by NJM5532D (Made by JRC Japan Company) (Or NE5532)amplifies the electric circuit to drive the mini headphone amplifier. These two features provide an awesome combination of high quality sound and a very powerful drive current for an optimum listening experience!  Our T2 amp adopts a Single Chip Microcomputer and Relay to control the muted sound when the device is OFF or first turned ON. It allows the device to warm up before transmitting sound, protecting the unit and your speakers and preventing that annoying “popping” sound that is heard with many other, less quality systems.  Please Note: The blue LED lights will flash for about 35 seconds when the unit is first powered on. This indicates that the unit is warming up. The blue lights will be lit solid when the amplifier is ready to be used!  SPECIFICATIONS:  Input Interface: 3.5 mm Stereo Jack Output Power:  32 Ω: 70 mW 64 Ω: 44 mW 150 Ω: 23 mW 300 Ω: 13 mW THD+N: 0.0015% SNR: 80dB Frequency Response: 20Hz—20kHz Residual Noise: 0.02mV Consumption Power: 5.6W PACKAGE INCLUDES: 1 X T2 headphone amp 1 X T2 user manual, 1 X Adapter

## Features

## Questions & Answers

**Q: Can these drive DT 990's at 250 Ohms?**
A: Hmm...well as a matter of fact, I'm presently listening to a Jason Mraz live recording on my Sennheiser HD700's which are 150 ohms impedance. I have my Astell and Kern AK380 set on "line out" and the SMSL volume pot is set to about 25%. And my friend, I can tell you it's plenty loud and clean! Hope this helps!

**Q: Does this come fully assembled?**
A: Yes, it’s fully assembled; you don't need to assemble manually.

**Q: Is this another one of those headphone amps that only have tubes for show?**
A: Hello,i have a little confused about your question. But this T2 is not only a headphone amplifier,it also is a tube amplifier.

**Q: Any recommendation in case I want to upgrade the tubes?**
A: I purchased a set of RCA 6688 (you need this one, not 6J9 - 6688 is model for the Chinese 6J9; American 6J9 tubes will not operate correctly). I also purchased a couple Phillips tubes - some New Old Stock from tubedepot.com, as another had mentioned, and they sound quite nice. I originally wanted RCAs and hoped tubedepot.com could deliver, but they only had Phillips, I found the RCAs on ebay and find its difficult to discern the difference in sound. I mention this because RCAs are preferred by many for audio tubes of this vintage.

    STUNNING ALUMINIUM BOX OF TRICKS
  

*by N***N on Reviewed in the United Kingdom on 13 March 2018*

OK so lets get one thing straight... I am no audiophile but I can appreciate quality and tend to purchase good quality hi-fi, tvs etc, not your no make brands but good but affordable items from companies such as Denon, Panasonic, AKG, Sennheiser KEF and so on. I had not heard of SMSL until a few months ago but knew that I needed more volume from my numerous headphones, tired of the low volume, even at max output, that fed the sound to my ears from the front output of my Creative Gigaworks T40 speakers attached to my pc. I also wanted to, on a relatively tight budget, experience something of the tube sound that I had read so much about. Now, I appreciate that the stock tubes that ship with this amp are not the best but for the cost the whole package has blown me away. For the last three days I have been feeding myself copious doses of Indie, Classical, Blues and so on and the sound stage has opened up no end. Listening to Miles Davis it is hard to believe he is not in the room. You can hear things that you have never heard before, layers of sound or even a single note that has escaped you even though you may have heard the song hundreds of times before. Together in Electric Dreams by the Human League stunned me last night with the clarity and depth of sound. My father is 87 and was and still is a huge fan of Sammy Davis Jnr and Frank Sinatra. He has been a proper audiophile in his time often spending a fortune on separates and speakers and he was amazed at how good some of his favourites sounded. My brother in law has moved with my sister to France this very morning and they have been living here for the last week as they had sold their house a week ago. Last night he was in here listening to his beloved blues and he is very hard to please. The Cheshire cat smile that dissected his face was something to behold and he immediately wanted all the details so that once settled across the water he could plumb one of these in. With this amp connected to the pc I would say that the volume is 2-3 times higher than it was before and yet creates no distortion at all. Now I can not have it turned up more than 60% if I want to keep my eardrums intact.In short, considering the cost this little beauty retails at, although I dare say not as good as other more expensive models at £100-150, it is a no brainer purchase. The Little Dot at twice the price might sound better, although I have never heard it so cannot comment, but is twice at much as this brushed aluminium box of tricks. I am now going to buy a pair of Soundmagic HP200 headphones and will be in heaven.

    The price to performance ratio is great for this little hybrid tube amp
  

*by A***R on Reviewed in the United Kingdom on 24 December 2017*

Here's the short version covering the key elements in this amp:Pros:- Slight increase in sound stage- Slightly more refined sound which makes it slightly more immersive- Clean Sound- And of course, it sounds warm(Potential) Cons:- Blue LED on the tubes can't be turned off- Inputs are at the front instead of the back- Takes roughly about 35 seconds to warm up- May not be powerful enough amp for headphones that have a high impedance- Doesn't give a strong "tube" soundPro or Con (depending on taste):- Slight bass boostNow the slightly longer review:The price to performance ratio is great for this little hybrid tube amp! Before I start the review, my initial rig was Hifiman HE400i paired with SMSL M3USB DAC/AMP. Since the HE400i are well known to be a cool and analytical headphone, I needed something warm to make it sound more "pleasant". I am no means an audiophile since my rig is nowhere near that standard.Initial thoughts when powered on the first time:The sound sounded compressed, suffocated and quite "muddy". This effected the drums, where the kick drum doesn't sound as tight and controlled which made it sound "muddy" and the female vocals where being held back by sounding suffocated. This may be due to slight bass boost, where the bass is not as controlled which can effect the whole imaging of the song. However, the "warm" sound is definitely prevalent and can be heard or felt. Of course, these are just relatively small things that can be picked up, nothing too serious.Thoughts after a week:WOW! THIS IS THE BEST THING EVER!!! Okay, that may be a bit of an exaggeration but the sound definitely sounded better. Sound stage has slightly increased, making the sound more open and instruments sound more refined making it slightly more immersive, making it sound more natural. I had to use EQ to tame the bass boost as it was the only factor that caused a bit of annoyance to me. I would recommend this amp for ideally for headphones that have 50 or below impedance and maybe headphones between 50-100 ohms. Anything higher can result in the headphones to not be powered efficiently.All in all, this hybrid tube amp is great place to start if you want to start investing into tube amps!

    AMAZING value amp
  

*by A***L on Reviewed in the United Kingdom on 6 April 2018*

I cannot say a bad thing about it. This has become almost my favourite bit of kit full stop. For it's price it performs wonderfully, doing a great job with a pair of GRADO SR60E's and various speakers.Excellent product, would buy again definitely.
