Purchased in 2022, but I quickly bought another mic pre, so I didn't have much opportunity to use this one. I've decided to sell it because it's a waste to keep it. The sound is outstanding. It was a great microphone preamplifier that conveyed a nice, silky sound. No original box. I will send the power cable and the unit itself. I will also include a power cable from Oyaide that cost around 10,000 yen. I'm listing it for less than the market price because I want to sell it quickly. Thank you.
