TacT Audio?

Does anyone have any experience with TacT Audio and their amps? Their new T-2 digital amp looks interesting.

Tact proudly presents the new T-2 digital integrated amplifier, based on the same amplification technology as M/S 2150 X.
Like the M/S 2150 X, which is widely recognized as the best sounding amplifier in the world, T-2 is completely digital amplification without any analog processing. It has ample power for any system configuration and it is 24bit/192kHz compatible. T-2 is extremely flexible with five digital and three analog inputs.


Tact True Digital Amplification, the sound of the future. The Tact Millennium is recognized as the first true digital audio amplifier. Other so- called Digital or Class D amplifiers have been various combinations of Analog and Digital technology, in most cases using analog feedback. TacT's True Digital Amplification is conceptually different from any other amplification in almost every area of design. Once you understand the fundamental differences you will realize that Tact's complete line of True Digital Amplifiers offer the potential of much higher fidelity than any other digital or analog design.

Having said all of this it is worth pointing out, that the Tact's True Digital Amplifiers are not amplifiers at all. They are D/A converters that just happen to put out enough current and voltage to drive speakers directly, without the need of any amplification. This way it will perform the functions of: D/A converter, Preamplifier and Power Amplifier, without having any analog circuitry after D/A conversion other than one coil and one capacitor performing a 60 kHz, 2nd order low-pass filter.
Essentially, the hundreds of active and passive components usually required for amplification are gone!

    Not me. I prefer tubes because they rock my audio world.

    A very interesting, to say the least, amplifier design. The volume control actually adjusts the level of the power supply feeding the digital circuitry. Since the "output" is a second order 60kHz filter the speaker wire and speaker load will become part of the filter's response. At higher wire/speaker impedance the response will tilt up. At lower there will be a reduction of higher frequencies, probably a dB or so. That could probably be adjusted with the digital circuitry already inside.
    Cheers, Ken

    Ken, Zingo....here's where I lose interest. I have heard that class and I'm not too impressed, to say the least.

    Class D technically aren't digital amps; TacT amps are digital as the only analog circuit in the amp is the speaker outputs. Ken is right that the volume control is just adjusting the output voltage. I think it's clever that the amp is described as a DAC that has enough voltage and current to drive a pair of speakers.

    I can understand your reaction, digital amplifiers seem to have rising distortion as the frequency rises. Unfortunately our sensitivity to distortion also rises with frequency, not a good arrangement.
    Evidently this company has solved this and other problems associated with digital designs.

    I'm going to be chatting with Boz from TacT Audio next week, and hopefully that will help shine a light on their technology and sound. In a few previous emails, he was showing me examples of horn systems powered by TacT amps supposedly because of their neutral sound, extremely low distortion (THD+N all power levels < 0.01%), and extremely low noise (SNR >110 dB). Oh technology...

    Dismissing Class D is like dismissing any other class of amps(A, A/B) because you heard a couple of bad examples.

    One of the best systems I have heard consisted of Magico Reference speakers powered by eight Acoustic Reality monoblock amps; six eAR Thaumaturge and two eAR 1001?s with a special 2.5 upgrade for the bass. All class D amps, IIRC.

    Well, I guess you are right. On the other hand, I don't recall ever hearing a class A or A/B that I would have considered particularly bad.

    It amazes me how many different amps, speakers, cables, etc. that are available for sale that are above your average user's interest level. It seems to me the good audio market is pretty big to support all these players.

    On the other hand, the lack of a power rating with this amp is interesting. Is it an 800W/ch @ 4 ohm DAC?

    My experience with Class D amplification(Hypex) has been very positive.

    Eh, maybe it's just my experience and subsequent observations with class D amps. I haven't heard one yet that impressed me beyond it making noise. That right there is what triggers my loss of interest.

    Kind of like a Yugo. My experience and subsequent observations with Yugo's [the car] are what would trigger my loss of interest in purchasing that car. No, I'm not comparing it to a Yugo. Don't get your panties in a wad. It was just used as an example that pretty much everybody could relate to.

    Yes, I know. Don't remind me. I don't like them at all and they are on my long list of things to replace. I have more important things on the audio-to-do list first.

    I approached Class D with a highly biased(pun intented)and preconcieved idea of how it should sound.I was pleasantly surprised to find that the particular Class D architechure I was listening to did not have the hard ,clinical and lifeless SQ I had expected it would.Instead what I hear is smooth and sweet sounding top end and excellent midband clarity.Where it falls short of the Class A/B designs with which I compared it was in the area's of dynamics and bass slam and control.

    As with other classes of amplification,not all are created equal but my experience with the Hypex designs have me convinced that Class D done right can sound very good indeed.

    Hi Zingo

    Would you min sending me Boz's E-mail in a private message, as I have not been able to get any respons through the Tact Audio email.
