Violectric HPA V550 and V550 PRO Headphone Amplifier

Well, the hype is true. Holographic soundstage, precise separation of vocals and instrumental parts. A tiny magic box that put to shame the muffled sound of my integrated DAC. That one is a keeper.

Good selection, helpful staff, quick and free delivery. What more can I say? And it was cheaper than Amazon or its Chinese version.

My headphone listening adventure began about 8 years ago with a purchase of Focal Utopia flagship headphones and a good quality amp and DAC joined together with Nordost cables to my ROON server. The electronic components (DAC and amp) at that time cost me about $7,000 CAD. Two weeks ago I received my LAIV Harmony 𝛍DAC and AUNE S17 Class A headphone amp by courier and even upon first listen I was blown away. I never realized that my Utopias could reach into the music with so much delicacy and bass richness. All without the treble edginess that my wife had on her planar phones. This is not meant to be a Utopia review, but I realized that the Utopias need very fine gear to release their abilities. Gear that cost me about $2,500 CAD. Amazing how much the audio gear has been refined in the last 8 years, for a third of the cost. Five thumbs up.

Nest place to order audio products.

One of the best headphones in the world.

Incredible service. Instant response to all questions.

Really best TWS IEMs I’ve ever listened to. I’ve had Sony xm4, Denon Perl Pro, B&W pi7. These are the best.

Nick is knowledgeable in audio and a good person to deal with. Heresponds to inquaries quickly and posseses good communication skills.

Very good experience. Easy decision to be a repeat customer.

The Arya Organics exceeded expectations. I'm listening to Stanley Turrentine's album Ballads as I comment. The experience is the closest thing to Saturday nights at Walt Harper's Attic when I was much younger. First and only time I heard MJQ in concert.

Another great transaction with Nick, always a pleasure dealing with him, vast product knowledge and very helpful. This was my first experience purchasing online and the shipping was super fast!
The Aune AR5000 is an absolutely incredible bargain and sounds fantastic.
it was my way of testing the water with a headphone rig and I was absolutely blown away at the performance!

This is truely exceptional product. The headphones are lightweight and comfortable. The system produces is a captivating experience. Instruments and vocals just sound 'right'. Most surprisingly, its got bass slam! Enough to satisfy any bass head junkie. I'm continuously blown away by it. It has exceeded all expectations. 5 Stars. It's that good!

Lovely full range sound rivals my overear cans. Great choice of plugs and sound filters though sounds marvellous with the pre installed green treble filter. Very comfortable and reveal many previously missed details from much loved songs. Great Noteworthy web site and service. Thanks.

Excellent guidance from the staff, answering my questions regarding the equipment and my particular setup and audio intentions. Made the sale. Also appreciated the very quick shipping and expedited delivery.

Amazing level up from my $300 headphone amp&DAC. The support and guidance from the staff was instrumental in my decision to get this amp and recommendation not to get the Bluetooth version as it would not add to my particular usage and audio experience. Very pleased with this purchase experience.
