t.amp s100 mk2
SergheiB 03.11.2019
I purchased a t.amp s100 mk2 for a recording studio as an amplifier for near-field monitors.

Pros: the appearance is pleasant, the amplifier is structurally reliable.
He measured the maximum power (source signal-generator with a resistivity load of 8 ohms) in stereo, parallel and bridge modes. The declared power and operating frequency range is in accordance with the declared manufacturer. I did not observe excitations at high frequencies.

Now the cons:

in the second channel, in the absence of an input signal, an insignificant background of the AC network is heard (in the first channel
this effect is not). You can put up with this.

The power transformer of the amplifier is noticeably buzzing. In this case, the upper cover of the amplifier resonates. In a quiet room it is noticeable.

Now the most unpleasant:
when playing the synthesizer in low register, or on the bassguitar, the sound is distorted and becomes very unpleasant itchy shade. At first I thought that I overloaded the input of the amplifier and I hear clipping. When checking, the input signal level corresponded to -18dB, and the output power did not exceed 4W / 8 Ohm. On load
4 Ohm / 6W effect is even more pronounced. I decided to check if the problem is in the signal of an instrument rich in overtones?
On a purely sinusoidal signal (source - signal generator THD 0.01%). The level of notice ability of spurious modulation is maximum at an input signal frequency of approximately 125 Hz. The effect is observed in both the first and second channels of the amplifier.

In general, the expectations were not met, if I can not solve this problem, I highly not recommend the amplifier.

Now a question for manufacturer technical support: I admit that this effect may be a single copy problem in the glorious t.amp amp family. If so, advise how to fix this problem. Email babii_serghei@mail.ru

Great sound, great detail, and good features for the price. Comparison with E-400.
Fauve 08.12.2019
Solid built quality, more than enough power for my speakers (Mission LX-2), and handy meters to make sure you are using a correct gain staging so that you don't push it unless you have to (as pushing an amp towards its upper limit might not do well to the speakers' tweeters).
I bought both this and the T.Amp E-400 for my speakers. The E-400 sounds a bit bigger, the soundstage is a bit larger, it's deeper but with a bit less clarity. I kept the S100 Mk2 because it's smaller, it has meters, no fan, and has a bit more clarity. It was a decision based on my job as a mixing engineer. I need something as revealing as possible. If I needed the amp just for listening I would probably get the E-400 as it's a bit more pleasing and less analytic, but I found the S100 clearer. Part of that is that it is brighter compared to the E-400, so you might want to consider it based on the signature sound of your speakers.

It just keeps going
Owen L. 28.08.2014
I have been using this week in week out for 3 and a half years. It just keeps going. No fans, no noise. It just switches on, does it's thing and then gets switched off. It is set up in a system that gets switched on from the mains and not on the switch on the front panel. It has never complained or missed a beat. I do not have to think about it. I am not always there to run the rig, but I know that whatever anyone throws at it, it will just carry on without throwing technical wobblers. That is my kind of kit. It drives 2 separate monitors and is easy to use. It is small and light. I like it a lot.

Holy crap this is awesome
MD 05.06.2019
This has been working well for me so far. It is relatively loud and awesome sounding for a guitar rig. I am using it with an amp that has a reactive load. Amp goes to reactive load, then the load goes to this power amp, then finally to a speaker. I can crank the amp and finely control the final volume with the power amp. Very clean sounding. Took off one star for feature because I wish it had combination speakon and 1/4" connectors. I had to purchase extra speakon to 1/4" speaker cables as I was not expecting it to only have speakon jacks.
