Monoprice MONOLITH - CAVALLI Liquid Platinum - Tube Hybrid Headphone AMP!!

This headphone amp is the powerful, sweet and detailed Alex Cavalli tube hybrid brought to you by MONOLITH. It regularly goes for $800.00, but I am selling it for $575.00 plus the buyer pays reasonable shipping fee. PLEASE NO HAGGLING - this is the cheapest you will find this amp, and it is barely used.

This amp is barely broken in, and it comes with all original materials. I have owned it for less than a year, and it is in perfect physical and working condition. MINT CONDITION. 

While I love this headphone amp, it is a waste for me to have it when I'm always listening to HIFI setup (speakers) nowadays, and someone should be enjoying this beautiful thing!

The critics love it, comparing it to the more expensive Cavalli Liquid Crimson, which I have never heard, and you can check out the wonderful Steve Guttenberg, The Audiophiliac's, review on this amp below...

"Meet the Monolith Liquid Platinum

The amp's front panel is straightforward, from left to right there's a power button, 6.3mm headphone jack, a second four-pin stereo XLR balanced headphone jack, volume control knob and a tiny button that switches between the balanced XLR and single-ended RCA inputs. There's also stereo RCA outputs. That's it, the Liquid Platinum is an analog-only device, there are no digital inputs. What we get instead are two tubes poking through the top panel, they're Electro Harmonix 6DJ8 tubes. The Liquid Platinum's all-metal chassis feels solidly put together. 

Some high-end headphones are insensitive beasts and need a lot of power to sound their best. That's why the Liquid Platinum can deliver up to 6.2 watts per channel, right up there with some of the most potent headphone amps I've tried. Even so, the Liquid Platinum is a desktop friendly size, a tidy 8.8 by 8.5 by 2 inches.

Liquid Platinum listening tests

The "big" Liquid Platinum just sounds right, sweet, yet detailed, bass is full, but not overly ripe. It drove every full size headphone in my collection with ease.

In a face off between the Liquid Platinum and Mytek Brooklyn headphone amps with the outrageously great Abyss Diana Phi headphones (review to come) it was easy to hear the two amps were quite different. The Liquid Platinum is more refined and pure sounding, the Brooklyn shrinks the soundstage and it sounds too lean and cool for my taste. The Liquid Platinum is in a different league with this very revealing headphone.

I next compared the two amps again with a much more modest Beyerdynamic T51p headphone, and again the Liquid Platinum's dynamic dexterity left the Brooklyn in the dust.

Moving to Sony's flagship MDR Z1R headphones, I compared the Liquid Platinum with a Schiit Lyr 2 tube headphone amp. The Z1R is an astonishing closed-back headphone, and the Liquid Platinum was a terrific partner, serving oodles of detail, excellent dynamic contrasts and airy treble. They were a total pleasure to listen to. 

The Lyr 2 was awfully good, the sound was palpable with terrific dimensionality, but it was no match for the Liquid Platinum's transparency. The Lyr 2 darkened treble detail, and dynamics were reduced, but the overall sound was still delicious with the Z1R. I'd call it a tie between these two amps.

The Liquid Platinum's other major design feature is its fully balanced circuitry. To determine if I could hear a difference I listened to the Diana Phi with the standard cable terminated with a 6.3mm plug, and then listened to the same headphone with an identical cable terminated with an XLR balanced plug. What can I say, the balanced connection might be a tad smoother, but if I have to struggle to hear a difference, then the difference isn't that big a deal.

So with either connection the Liquid Platinum is superb, a truly remarkable sounding amp for $770."
