I have for sale a new Monolith Liquid Platinum balanced tube headphone amplifier by Alex Cavalli. I received this amp as a late birthday gift back in December. The box is unopened and should have all of the included goodies (tubes, power supply, etc.) The pictures are from Monoprice's website.

Steve, The Headphone Guru, concluded that the Liquid Platinum was “... a remarkable journey testing this great piece of equipment out. My notes put it as one of the best sounding amplifiers under $1,000. I found that acoustic songs are very detailed and intimate. The detail of the music is exceptional, even at higher volumes. While the soundstage may not be vast like some other mid-range amplifiers, it was more than adequate, I’d say…just right. When you listen to songs with emotion, this amp really does “amplify” those emotions and brings it home...I can say this with confidence, you’re not going to get a better sounding amp in this price range.”

Dave Hanson, reviewer for Enjoy the Music, awarded the Liquid Platinum a “Best of 2019” recommendation. He concluded that “...For a lot of people this amp is going to be an "End Game" score. It's a hell of a lot of amp for $799. The Monoprice Monolith Liquid Platinum does a lot of things well, sounds great as it is, and I see that there is potential for it to grow, if you want to roll tubes or switch out the power supply. [Owner's Note: Do Not Switch out The Power Supply as per Alex Cavalli]...Either way, you have an excellent foundational piece to build around at the center of your system...Overall, the Monoprice Monolith Liquid Platinum is an extremely beautiful sounding and richly detailed amp. It is able to uncover a lot of layers to the music that other amplifiers in this price range can't seem to reveal. To me, for $799, this is certainly one of the best options out there. In terms of emotional gravitas and truly experiencing the music, it is tough to beat at any price.”

I'm asking $475 or best offer plus shipping. The manufacturer's suggested retail is $799. I accept PayPal but the buyer is responsible for paying their fees. I also accept USPS money orders. I will only ship within the USA.

I have great feedback on Ebay as Gelajoy (1100+ rating at 100%.)
