Astro Electronic Planning AST-KT88MVIPSP Monaural Power Amplifier

Astro Electronic Planning has revamped its lineup of high-grade amplifiers to all monaural versions. By converting stereo amplifiers to monaural amplifiers, higher output power and deeper sound can be obtained. This is especially effective in improving acoustic performance when driving highly loaded speakers. When the sound field is unbalanced during stereo playback due to room acoustics or speaker placement, mono conversion integrates the output of both channels to obtain a uniform and stable sound field,Audio symmetry can be improved.

Another important point not to be overlooked is that the weight of a single unit is reduced to less than half (compared to the company's conventional stereo amplifiers) compared to full-size bulky stereo amplifiers, which makes installation and other handling much easier.

Beautifully Mirror-ProcessedThe 1.6mm-thick high-quality stainless steel chassis and component mounting mid-plate steel areClear FinishThe robust construction with 1.5mm-thick oxygen-free copper prevents resonance from inside and outside, contributing to noise-free, crystal-clear high sound quality.

The transformer uses an original transformer that pursues sound quality without compromise while keeping the price low. Gold-plated, high-grade terminals are used for input and speaker output terminals.

For the self-bias capacitor, the AST-KT88MVIP/SP uses an order of magnitude larger capacitor (4000 micro) compared to the 200~400 micro capacitors used by most other manufacturers. This allows the AST-KT88MVIP/SP to have the same sound quality as a fixed bias, even though it is self-biased. Feel free to replace various KT88, KT120, and other compatible vacuum tubes produced by tube manufacturers around the world to bring out the best performance.

In addition, the use of UL connections increases output power, contributing to improved sound transparency and resolution. The volume is controlled precisely by using a click type attenuator with 31 contacts.
