I love Modwright products and have 2 modified Oppo’s. I have not listened to the LS100 so I can’t comment on it. I have owned an MZ2 and I have a MicroZOTL preamp. The MicroZOTL preamp is a keeper for life and the MZ2 can’t be beat at the price in my opinion. The MZ2 is the Swiss Army knife of audio since it’s a world class preamp, headphone amp and if you have some very efficient speakers, the 1 watt integrated amp is unbelievably good.
