Customer Reviews
Bought my amp new from mimic. Got here fast and packaged well. LOVE THE AMP. Current batch of tubes are all PSVANES. Which sound good. Replaces the 6sn7's. Amp is bigger and more attractive than the pictures indicate. The sound is amazing on my ZMF Aeolus on high gain. My Hifiman Arya Organics on low gain and on my Stax L700 mkII (also from Mimic Audio) through the preout. No sound difference between xlr and single ended output with GOOD cables. I did have some right channel imbalance noise for about 10 hours in the beginning no matter the 6sn7's i used. must have been from the 6080's but it worked itself out after a while. And the source output selector knob has a bit more play than id like. But other than that it is worth every penny and the sound cannot be oversold. I am coming from a felix echo mk2 which is LIGHT YEARS behind this.
