What was interesting was that these spikes are not present with the Super T passing low frequencies. But at its very affordable price, it should provide acceptable performance when matched to high-sensitivity speakers.—John Atkinson, Classé Delta Mono monoblock power amplifier, Pass Laboratories Aleph 0 monoblock power amplifier, Parasound Halo JC 1+ monoblock power amplifier, darTZeel NHB-468 monoblock power amplifier, Accustic Arts Audio Mono II monoblock power amplifier, Dynaco Stereo 120 transistor power amplifier, Verity Audio Monsalvat Amp-60 power amplifier, McIntosh Laboratory MC462 power amplifier. speakers output. The output impedance was a moderately high 0.35 ohm at 20Hz and 1kHz, rising to a very high 5 ohms at 20kHz, the latter due, I imagine, to the series low-pass filter used to prevent ultrasonic switching noise from being radiated from the speaker wires. The Sonic Impact T-amp weighs little more than a pound and will fit in the palm of your hand. If you have bananas for fingers you may find operation a little tricky. These graphs were all taken with the volume control wide open; there were no significant changes in response at lower settings. With the volume control set to 12:00, these rose to 19k ohms at low and midrange frequencies and 13k ohms at high frequencies. over current protection, It can even be battery powered with (8) AA batteries. Switching in the low-pass filter smooths these spikes over (fig.7) but doesn't eliminate them, confirming that they are characteristic of the Sonic Impact, not the result of any unwanted interaction between the ultrasonic noise in the amplifier's output and my Audio Precision test set. The Gen 2 T-Amp features the same sound quality that made the original T-Amp famous, as well as the ability to operate off of 8 AA batteries. Sonic Impressions: Sonic Impact T-amp vs Jolida JD301 Quick summary: Within the confines of SI’s 6 meager watts, which are quite sufficient in my setup, it is a better amplifier than Jolida.

I preconditioned the Sonic Impact Super T amplifier with both channels running at one-third maximum output power for an hour into 8 ohms, but, as expected with an amplifier with a high-efficiency switching output stage, the chassis was as cold at the end of that period as it had been at the start. I bought at $29.00 “Sonic Impact” T-Amp. SI wins out mainly because of its resolution and transparency. Fig.3 Sonic Impact Super T, small-signal 10kHz squarewave into 8 ohms. The shortfall was a little worse into 4 ohms: 9.2W (6.6dBW) instead of 11W (7.4dBW). Sonic Impact fans will be delighted to find out that the new Son of T-Amp is an altogether better constructed amplifier than its predecessor and a bargain at $139. {"modules":["unloadOptimization","bandwidthDetection"],"unloadOptimization":{"browsers":{"Firefox":true,"Chrome":true}},"bandwidthDetection":{"url":"https://ir.ebaystatic.com/cr/v/c1/thirtysevens.jpg","maxViews":4,"imgSize":37,"expiry":300000,"timeout":250}}.

Yes, that is a $30 amp outperforming a well-reputed $350 integrated amp. Fig.4 Sonic Impact Super T, distortion (%)vs 1kHz continuous output power into (from bottom to top at 2W): 8, 4, 2 ohms. Fig.5 Sonic Impact Super T, THD+N (%)vs frequency at 2.83V into (from bottom to top): 8, 4, 2 ohms (right channel dashed). Interestingly, the Super T clipped at lower powers when powered by the linear 12V Monolithic supply with which Wes Phillips experimented.

View cart for details. On the front there is a combined volume control and on/off switch on the front. Intelligent short-circuit and over-temperature protection ensure amplifier longevity. Above 1kHz, however, the amplifier clearly has trouble maintaining its linearity into all loads. Dayton Audio has taken the technology developed for the Sonic Impact 5066 and perfected it in this hand-held digital amplifier. The series output filter, however, will interact with the load impedance, and this interaction can be seen in fig.1, which shows the Super T's frequency response with the amplifier driving resistive loads ranging from 2 to 8 ohms, as well as Stereophile's standard simulated loudspeaker.

With the latter set to its maximum, the input impedance measured a fairly low 7.8k ohms in the bass and midrange, dropping slightly to 6.5k ohms at 20kHz. Into 2 ohms, the amplifier didn't clip but simply stopped at 13W (fig.4, top trace). T+A Presents a Discussion of Their HA 200 Headphone Amp, HV Series Technology, and Solitaire P Headphones!

The amplifier's power supply is a 12V, 3A wall wart, and even with the Super T's high-efficiency output stage, there just aren't enough volts and amps to be delivered into the load to generate higher powers than these. The second harmonic is the highest in level, at an excellent –83dB (0.007%), with the third and fifth harmonics lying at –90dB (0.003%). Channel separation was excellent at almost 90dB in both directions at 1kHz, this decreasing (due to the usual capacitive coupling) to a still-good 70dB (L–R) and 62dB (R–L) at 20kHz (not shown). Even at the level of a few millivolts, unless this energy is filtered, you can never be sure that you're not actually measuring the interaction between the RF content and the test gear instead of the absolute performance of the amplifier under test (again, see the PS Audio review). The Dayton Audio DTA-1 is the perfect replacement for the now unavailable Sonic Impact 5066 NIB class T amplifier.

Then I had an epiphany. Something went wrong. Sonic Technology home the CMS MDS 3.0 compliant sound amplifiers, ultrasonic rodent repeller, EMF Detector and other quality products since 1981.
