Monolith Liquid Platinum Headphone Amplifier Balanced - Designed by Alex Cavalli

Description

Selling my Monoprice Liquid Platinum headphone amplifier with less than 10 hours of use. It was barely used and is in excellent condition with no visible marks or performance issues. I have tested to make sure everything works great. It includes the stock tubes, original power cord and instructions manual. Does not include the original box, but does include original boxes for power cord, tubes, soft bag and inner packaging, please see photo. Order will be shipped out next business day with Fedex tracking. Please let me know if you have any questions, thank you!
This is a very powerful amp that will benefit by attaching it to a dedicated DAC and using high resolution files. I would describe this amp as neutral warm and has exceptional detail even at higher volumes. If you are looking for a powerful amp to drive your headphones with high volumes and can swap out tubes for an even better sound, you're not going to get a better sounding amp in this price range.
