Valutronic CM-130



2x50W @ 8 Ohm top quality stereo power amplifier*.
A semiconductor amplifier based on tube amplifier principles to acheive maximum listening pleasure, without the drawbacks of a tube amplifier.
898 Euro incl VAT and shipping to all EU countries.
We use the cabinet, coolers and transformer of an STA-102 PA power amplifier, and replace the electronics with our own.
So we combine the strong PA cabinet, the high-capacity coolers and rigid transformer with the top-quality sound of our own electronics.


If you have the knowledge needed to build a poweramp yourself, or want to build top quality active speakers, you can buy our mono poweramp modules – essentially the same amplifiers and save quite a lot of money. Click here.

*) The sensitivity is high, so the CM-130 can be connected directly to CD- or DVD players, without using any pre-amplifier.

The amplifires in the CM-130 are not designed the way you normally do. We used semiconductors, but stabilized the amplifier the way it is made in high quality tube amplifiers.
We ended up with a power amplifier with the clarity and pureness of a tube amplifier, but with the semiconductor amplifier´s firm and exact bass and long-time stability. A unique combination.

Valutronic CM-130 is made for people with very high demands.

The first thing you will notice is the detailed sound. Just as in high-quality tube amplifiers, details are reproduced without being damped by or interfered by other sounds. All sounds are heard well separated from each other if the recording is good.

We have especially worked on eliminating TIM (transient intermodulation distortion). You can therefore enjoy music for hours without listening fatigue.

A well recorded singer will sound real, not recorded (assuming you have good enough speakers, of course). The same goes for acoustical instruments. But of course, modern synth music can be full of strength and "rawness" if the recording is made that way. The only time you migth wish for lower detail is when you play low bitrate mp3 recordings. mp3 distortion you might not have heard using an ordinary amplifier will probably be heard using the CM-130. It simply hides nothing.

Wonderfully deep and precise bass response.

This is where the CM-130 is not comparable to tube amplifiers. When it comes to bass, the CM-130 is better than most tube amplifiers. The bass is firm and exact. There is no problem separating different bass instruments playing simultaneously from each other. Phaseshift and distortion are totally neglectable, through the whole audio range.

Interested in the technicalities that makes this amplifier one of the best, no matter what cost? And why we referred to it at a "tube amplifier without tubes" in the beginning of this page? Click here.

Of course the above assumes you connect the CM-130 to high quality loudspeakers. No amplifier in the world sounds better than the loudspeakers it is connected to. We use CM-130 together with a pair of SQ-50 studio monitors in our shop in Gothenburg, Sweden.

We also have an old NAD 3020e to compare to. The NAD is old, but except for its limited output power it is still considered one of the best sounding amplifiers. However, compared to the CM-130 it is really bad. When we let our customers listen to the CM-130 for a while, and then switch to the NAD (playing the same music on the same CD player using the same loudspeakers) they often don´t even want to listen. Yes, the difference is that huge. The NAD:s bass is much less detailed, when playing one of our test recordings with a mix of bass drum, synth bass and bass guitar the NAD can´t separate the different bass sounds very well. They are totally clear on the CM-130.
On the NAD, midrange and treble sounds "flat" compared to the transparent sound of the CM-130. Faint background sounds are masked by stronger, and dissappear. The sound becomes more flat, loosing ambience.
Don´t misunderstand us. We still consider the NAD a good amplifier. It is just that the CM-130 is so much better.
