About: Bellari HA543 Headphone Amplifier

The Bellari HA543 sets a new standard for what is possible in a headphone amp.

You can pay more, but can you get more?

  • XLR balanced inputs
  • 1/4” and 1/8” headphone outputs
  • Pass thru (RCA out) that also works when using the XLR inputs
  • Mute
  • Power
  • Enhance feature

One of the biggest issues to consider when buying a headphone amp is how much coloration it has (how much the amp adds to the original music). All amps sound different, generally that difference is called coloration, and some amps have a lot more than others. This is an issue for the end user when deciding what to buy. Do you buy an amp that has a flat response or one that has some kind of sound altering circuit adding coloration to your music? The HA543 addresses and completely solves this paradox. It features the best of both worlds. The HA543 is as flat as flat can be unaltering the original program material keeping it as true as possible. No coloration, no gimmicks nothing just absolute pure reproduction of the original material, and it sounds absolutely amazing with a good pair of headphones. Then, when using the HA543’s Enhance switch, coloration circuits are added changing the overall sound characteristics. The end result is an amp that makes the vocals sound more dominant, cymbals much more open and sharpens up the lower frequencies to give the bass very tight detail. It is not an EQ there’s a lot more going on than just a simple EQ. It makes the HA543 two headphone amps in one. Want it purist flat? Its got that. Want a headphone amp that has some sound enhancing coloration? No problem.

Headphone amps can cost anywhere from $99 to $1999. It is hard to find honesty in what is a real true improvement in build quality or sound. Reading through the online reviews to get a good idea of what to buy is difficult when it is clear that some reviews are paid for and some reviews are not taking into account the full story, in personal experience or knowledge. What I can tell you honestly, is that the HA543 is hand built in Salt Lake City, UT by people who have been in the industry for a few decades. We have seen it all, from companies selling the equivalent of snake oil and charging outrageously for it, to honest companies that have unfortunately fallen by the wayside.

The Bellari HA543 is a truly remarkable headphone amp. It will bring your set up to the next level, and get you fully addicted to this hobby. While the HA543 is not the least expensive headphone amplifier available it is truly one to own.

Reviews: Bellari HA543 Headphone Amplifier

BRYAN B. - 04/21/2022

&lt;p&gt;This Bellari is really fantastic. The purity of sound reproduction is perfect. The construction of the steel casing is made incredibly tough and the switches have a solid action and operate well. MADE IN USA. A beautiful piece of audio equipment sonically and visually. It came safely packaged and a unusually good quality ac/dc adapter is included.&lt;/p&gt;


&lt;p&gt;I can&amp;#39;t believe I only paid 119 CAD for it, should have been twice that price. My AKG headphones never sounded so good. The enhance button is absolutely magical - from an absolute 100% flat studio quality sound to a very slight high and low frequency addition, great for very loud or lower, soft volume listening. I believe this model is a relatively new product from the USA and deserves WAY more positive reviews. If you&amp;#39;re thinking of a headphone amp purchase, JUST BUY IT. I was really happy with the Ordered it online and and picked it up within one week delivery from the states. I have been an audiophile and bass player for a very long time. You can trust my judgement on Bellari.&lt;/p&gt;

Bottom Line:
Yes, I would recommend this to a friend
