Mighty Clones returned to the Mono & Stereo for the test and review. I've already wrote a lot about this brand products and awarded 55 PM mono amplifiers with Mono & Stereo Highly Recommended award. This time I'll take under the loupe SG1 Schumann Resonator, AP2 preamplifier, 25iR integrated amplifier and ASHER DAC. Lots of work and fun ahead! Stay tuned!
