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

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.

You could sum up the whole idea of a PA power amplifier in a single word - sound. The power amp is a crucial part of a musician’s live sound.
