Luxury Precision EA4 Flagship Portable High-Power TubeAmp (Like New)

First order of business - full marks to the Musicteck team. Received a sealed, brand new unit for my "like new" purchase. Properly packed and delivered halfway across the world in a flash. Overall a top notch experience.

On to the EA4 itself: I was in the market for a portable amp specifically to power my headphone collection, specifically the Sus OG, HD800S, and a heavily EQed Final D7000. Shortlisted a few options - XD05 Pro, C9ii, Enleum HPA-23, and of course the EA4. I didn't have the time/opportunity to demo each of these, so my primary source of information was other users/reviews on the Internet. It came down to Enleum vs EA4: I ultimately settled on the EA4 for its unique and many sound shaping options and superior aesthetics (yes at this price point that matters).

Now, 6.5W (@32ohms) of power is a serious number, even for a desktop unit let alone a (trans-)portable one. Certain manufacturers have gained notoriety for obfuscating power numbers in creative ways to avoid admitting the limits of their engineering. I of course lack the equipment to accurately test the EA4's claim, but the sheer ease with which it drove my OG Susvaras (with a 4db sub-bass shelf mind you) makes it very clear the EA4 is not mucking around. There is detail, space, authority, control, rumble - all those adjectives that jump in one's mind when they hear a pair of cans like the Susvara driven right. It is quite unbelievable. This not-so-little thing is right up there competing with serious desktop gear.

But the EA4 is more than just power. It has refinement and smoothness in spades that works well with quieter compositions, but also surprisingly with more aggressive tracks. Don't be fooled by the tube-centric design - this amp can punch when it needs to. I am yet to find a pair of headphones, or a track/genre of music that hasn't sounded delightful on the EA4. I won't lie - I had my doubts about the EA4, but 2 weeks in, I am sold. This is a long-term keeper, something that will unlock where and how you listen to music and what headphones you can use away from your main setup. It might just become your main setup. The edgy design, weight, lack of built-in DAC, and price, are a few things you'll need to get creative about, but once you find a pairing, and a way to carry them conveniently on your person you will unlock a whole new dimension of listening.

TLDR; buy it blind! And preferably from Musicteck.

Recently I’ve been testing MK475, PB5 and the EA4 was just a next level. Organic, natural warm sound with huge soundstage and deep bass. I love the options to tune the sound for different headphones.
