I have a Liquid Platinum as well. It’s heavily modded, with upgraded caps, an upgraded volume pot, and I’m using adapters so I can use upgraded tubes from the 12UA7 family. I didn’t like the sound of it with stock tubes or in stock form. It lacked clarity, dynamics were soft, and it sounded muddy. Now, it’s one of the best amps I’ve heard. The upgrades let the LP breathe, improved dynamics, clarity and details.That's good to know, thanks!
I really like the Gilmore Lite Mk2, but there are a few things about its sound that aren't quite to my taste, and the Auteurs seem to accentuate these traits more than other headphones as they really let you hear amp deficiencies/differences.
I am also looking at the Cavalli Liquid Platinum and Feliks Espressivo Mark II, but the Flux is by far the front runner. I just wish there were more impressions/reviews of it.
It was my favorite amp until I got the FA-10. It still does some things better than only tubes can do. Like provide a 3D soundstage, airy treble, and provide a even more meaty midrange, with superb bass impact depending on tubes used. Also depending on tubes, it can almost match the dynamics of the FA-10 with one caveat, it needs to be modded. Otherwise, I would say pass on it and go straight for the FA-10. You get everything that a modded LP can do right out of the box.
