2019年3月20日 · I recently reviewed the Linear Tube Audio MicroZOTL MZ3 as a one-watt integrated amp. In that review, I covered the history, description and design of the MZ3. This is a review of the MicroZOTL MZ3 as a stand-alone preamp or, …

The MZ3 is quite light, thanks to the lack of output transformers, it is relatively small at 10" x 4.75" x 8.5" and could fit very easily on a desk. Looking at the top, there are four cutouts for the four tubes that allow the MZ3 to operate. The MZ3 takes two 12SN7 acting as power tubes via jumpers, and it can also accept 6SN7 tubes.

The MZ3 is the highest expression of the patented microZOTL technology as a headphone amplifier, a preamplifier, and integrated amplifier in a desktop-sized package. The MZ3 has a beautiful new low-resonance aluminum chassis and offers reference-level sonics through upgraded internal components, premium tubes, and a digital control system with ...

2018年12月21日 · The microZOTL MZ3 represents the evolution of the microZOTL technology as a headphone amplifier, a preamplifier, and a 1 watt speaker amplifier in the external power supply form factor of the MZ2. Incorporating almost all of the technology enhancements recently released in our new microZOTL Preamplifier, the microZOTL MZ3 is the result of years ...

2019年11月6日 · Listening with my Audeze LCD-4, the MZ3 has a sound that is slightly more neutral than a typical tube amp, but it is still natural sounding. I personally would consider it neutral; others may consider it ever-so-slightly warm. It’s also, full, enveloping, and easy to get lost in the sound and just not think about anything else.

2019年7月30日 · The LTA MZ3 is a Class A push-pull amplifier that utilizes two amplification stages (12AT7 input tubes and 12SN7 power tubes) and no feedback. Of course, the patented David Berning ZOTL circuit is central to the design.

These all-purpose medium-mu triodes with a gain of 20, transconductance of 2.5mA/V and internal resistance of 7'200Ω were designed when space and energy savings were no consideration.

2020年11月1日 · The MZ3 sails effortlessly through some of the most challenging high resolution, complex music files we've thrown at it. And Linear Tube Audio makes experiencing an MZ3 (or any of their equipment) in your own home, within your own system, quite painless with their 14-day in-home audition policy .

If that describes your current system, Linear Tube Audio's MZ3 really is a fab problem solver for a very fair price. It's got all the mod cons of a year 2020 preamplifier. It also makes one terrific headfi amplifier for HifiMan's Susvara and other fast earspeakers which hope for just a bit of gravitational and textural influence.

2020年7月2日 · 在移动设备中使用的LRA可以达到1到1.7G的加速度，类似尺寸的压电致动器则能达到2.5到5G的加速度。 LRA功耗比压电致动器加上CapDrive压电驱动器一起消耗的还多。 与ERM电机相比，LRA的另一个优势是功耗更低，后者更适合电池供电的移动设备。
