About The Audio Tailor

Thank you for visiting The Audio Tailor.

We’re Stuart, Gabby, Nathan and Vaughan. It’s a pleasure to have you here!

The first question we get from customers usually starts with, “What’s the difference between...”

When you’re shopping for new speakers, a turntable, or even thinking of putting together that home theatre of your teenage dreams - you’ll likely be faced with stacks of comparisons.

Why would I buy the Bluesound Pulse 2i when the Flex 2i is half the price?

Is Boulder the best?

Should I wait for a sale? Or get this now? What will I be missing out on when the new model comes out next year?

Endless questions. Lots of FOMO. Loads of hmm-ing and ha-ing.

And there SHOULD be.

Because you don’t go to a Hi-Fi store and drop $2000, $3000, or $15000 on something you're not 100%, positively, secure-in-your heart sure of.

It’s a lot of hard-earned money on the line.

Imagine doing hours of your own research. Reading up the suppliers’ websites, taking notes from Hi Fi blogs, categorizing the differing opinions as you trawl r/audiophile. You know what you’re getting. You’ve narrowed the online stores down to the final five. You’ve checked and re-checked that you’re getting the best deal. You’re sure you’re not getting ripped off by shipping.

You hit the “Checkout” button. Momentary relief!

That is...

Until your speakers haven’t arrived by the estimated delivery date and you have yet to hear a peep about its progress.

Until your new turntable arrives with a crack in the dust cover.

Until your long-awaited amp set-up fails to deliver the kind of sound you had in mind. Now you’re not even sure if you got the right one anymore, or how to troubleshoot it.

What could possibly be worse?

What about: No after-sales service. No phone number to call. And no one responding to your tickets.

Not to mention the hundreds of man hours you’ve already lost on reading layman opinions from the likes of Graham H. from Melbourne and Sarah D. from Perth; dutifully scrolling through pages and pages of reviews. Torturing yourself by looking for all the ones with less than 3 stars... when you could have been sitting back and diving into a whole new world of immersive sound and deliciously satisfying body vibrations.

Would it make sense to go to audio specialists that know brands, specs, and installation like the back of their hands?

Should you spend less time on weighing up pros and cons and more time enjoying good music?

Want to get the absolute best home theatre for your budget and surroundings without the weight of 100++ brand offerings bogging you down?

We like to think so!

And that’s why we’re here. Two things to know about us:

Thing 1: We were voted Australia’s 2021 Hi Fi Retailer of the Year (Yay! And THANK YOU!)

Thing 2: This is purely because we are sound specialists and audioheads - NOT salesmen.

We got into this business because we genuinely love audio and because we realized there was a lot of faceless dropshipping in the HiFi industry - and not enough expertise out there. People who keep coming back to us do so because they’re getting attention to detail and individualized solutions that they can’t find elsewhere.

Our clients don’t need to worry about budget, brand name, or size.

All they need to worry about, is talking to us.

Because, when you come to us, you’re in for a conversation.

We want to know the picture in your head.

That final portrait of you back from the flea market with Pearl Jam’s Ten, eager to place it gently upon a turntable you haven’t quite decided on yet.

A summer barbeque in your garden with the boys. Having a yarn around a beer-filled cooler while appreciating the crisp, clear, quality of sound streaming through the open doors of your listening space.

The kids having mates over - quiet for once - immersed in a good movie, lights out, in the comfort of the home theatre that is your pride and joy. “I wish we had one of these at our place!”

Once we know precisely what your ultimate scenario looks like, we’ll want to know what you’re working with.

What kind of budget have you set aside?

What’s the existing set-up look like?

How big is the listening room you have in mind?

How much ambient light is coming in?

Are you running drywall or wood panelling? Carpet or hardwood?

What about room resonance and reflection?

No idea what we’re going on about? No worries. We intend to talk you through all that. Our aim is that you get the absolute best sound system for your home, at a price point you’re happy with, and an aesthetic you can’t help but want to show off.

To get to this end goal, an unhealthy interest in all things audio simply isn’t enough. That’s why we spend countless hours behind the scenes sourcing products from only the most reliable brands and trustworthy suppliers - regardless of their branding and marketing.

We don’t rely on them to tell us what’s good about their equipment. We’ve developed our own proactive testing process to judge what’s what. So you get hands-on knowledge every single time. Coupled with our tight networks and stable supply chain meticulously refined over the years, we strive to ensure that the experience you get at The Audio Tailor is personal, seamless, and painless.

Personal, because it’s uniquely you in musicality, design, and taste. Your options are hand picked by us from amongst some of the world’s biggest, best, and most dependable brands.

Seamless, because we’re only small. You get one of us. Not one of dozens of salesmen milling about the place, working for commission and pushing the most expensive products.

Painless, because we don’t recommend anything until we’re clear about your needs. We follow up with you to make sure everything’s arrived in one piece. For us, the transaction isn’t over until your equipment is safely installed and fully satisfying.


Some of the big things we feel are missing in the HiFi world are:

  • The need for expertise before, during, and after the sale
  • A vast wealth of comparative knowledge, and
  • A commitment to end-to-end service.

At The Audio Tailor, we hope we’ve made it clear that service doesn’t shut off when a problem pops up. It’s an opportunity to tighten the ship we run, bolster our 5-star reputation, and most importantly - make someone’s day.

Hi! We see you’ve actually made it to the end of this page. Love it!

We’d like to end this by giving a shout out to all the enthusiasts and audiophiles we’ve been fortunate enough to work with over the years. It has been a privilege to share our desire, passion, and journey for the purest sound and finest entertainment solutions for your homes and businesses.

Thank you to all our customers - past, present, and future - for helping us chase after something above the ordinary.

To make your audio dreams come true - call, email, or hop on down to our Brisbane store.

We’re looking forward to meeting you!

Brand Description

You’re interested in Boulder’s range of amplifiers and pre-amplifiers? Good. We’re already excited to get started. You clearly know your stuff. If there’s anything we love, it’s working and talking with people who are as interested and passionate about high-quality, exceptional sound equipment - like we all know Boulder has been producing since day one - as we are!

The choice of preamp can be the making or breaking of a home theater, hi-fi system, or professional studio setup. As the conduit and shaper of the audio signal from your audio source to your amplifier, it’s doing a lot of the heavy lifting, figuratively and literally! You can’t put out a fire if the hose is too narrow and there isn’t enough pressure to get the water to the nozzle. If the preamp you select is not truly compatible with the other components in your setup, you can’t spend or tweak your way out of the issue. You’re left with a huge fire truck, a gleaming golden nozzle, and nothing much coming out the end. Preamps get that water pressurised. And Boulder does a spectacular job of that pressurisation.

That’s why at The Audio Tailor we’ve spent hours tinkering away with different systems on your behalf. Seeing what goes with what, seeing which preamps make which amplifiers and speakers truly sing, and which ones that - despite being great individually, when combined - introduce muddines or lack of clarity to your audio. We’ve been pairing Boulder’s fantastic range of amplifiers and preamplifiers into amazing systems for years and have a wealth of knowledge around specific quirks and sneaky techniques to get the best out of them.

When you come into The Audio Tailor, you don’t just get the benefit of our years of obsessive mixing and matching or our nonstop testing of incredibly high end componentry. You also get our very real desire to make sure that your system is the absolute best it can be. We desperately want your system to be exceptional, bespoke, and suited perfectly to the space you’re installing it in. Why? Because once you’ve experienced the difference in great sound that gear like Boulder can create it feels criminal to not want to share that with as many people as possible.

The reality is there are cheaper amps on the market. But if you're here looking into a Boulder, that means you're not just hunting for a bargain, you’re after exquisite sound. That means we need to talk!

Be it over the phone, across a thread of emails, or (our favourite) seeing you in person when you drop into our Brisbane venue, we need to know as much about your sound and system requirements as we can in order to get you the sound setup of your dreams.

Tell us about the size of your space. The kind of music you listen to. The reflective surfaces, the type of curtains, the furniture. Is there an enormous window in your room with a spectacular view? Great, let’s compensate for the acoustic reflections from the glass. Is the furniture soft or hard? Wooden or metal? Let’s make sure we’re matching your finishes with the unit’s paneling. We’re going to make things seem integral to the room, not separate and plonked in.

If you have an enormous set of priceless crockery on display as well, let’s make sure we do some vibrational dampening so those precious heirlooms don’t bounce off the shelf the first time you power everything up. We want to know everything. Because we love great audio and we are obsessed with making it perfect for you as well. Heck, we’ll come over and look at your room, just to get the perfect gear recommendation for you.

Whether you need a preamp with a super low noise floor to run from your turntable, an amplifier that will pair well with your existing speakers, or an entire system that has a small physical footprint but can produce big, beautiful sound - we know our stuff. Let us show you how easily Boulder can achieve all these goals - and more!

Are we a bit nerdy about audio? Yes. And proudly so. Because, like you, we understand that it matters. We’re talking about a significant investment in setting you up with a system that will last you for years and years. We aren’t about impulsive decisions, because this isn’t disposable throwaway equipment.

Case in point: If there’s one thing you know for sure, it’s that Boulder is expensive. And if you’ve read up to this part of this article we’ve written just for you - that means you know a few things:

  1. That you’ve done your research. Sure, there are a few places you can pick up Boulder amps and preamps (you don’t have to buy ‘em from us).
  2. No matter where you get them from, they’re going to be similarly priced. Because when you get to this stage of “high end”, it’s about technology not profitability.
  3. That if you’re already spending this much on a Boulder - you’re not prepared to skimp on a few hundred bucks to get a cheaper deal if it means anything less than end-to-end customer service and “we’ll right any wrong” guarantees.

In short, with Boulder amps being the price of a small house, it might be a risk for you. But, it’s a risk for us too.

That’s why we don’t rest until it’s done right.

And, if we can be a little proud, that might be one of the reasons why The Audio Tailor was voted Australia’s #1 Hi Fi Retailer in 2021. But we don’t like to brag about that. We just do the job properly, anything else is just extra.

Boulder is a brand that time and time again proves its value and versatility in a variety of different circumstances, systems, and setups. Their wide selection of excellent preamplifiers and amplifiers gives multiple options for customisation in your setup.

The Boulder team have been manufacturing incredibly high end preamplifiers and amplifiers for over 35 years. Based out of Boulder, Colorado, the company was founded by audio engineers who were interested in one thing only. Perfect sound.

Originally catering to a professional market, Boulder preamps were exclusively found in recording studios and broadcasting facilities. Since this beginning they have branched out into the high end consumer market without any compromise to their build quality or attention to detail. That’s the kind of company values that really resonate with us here at The Audio Tailor. They don’t compromise on their build quality, no matter the market.

That’s why if you are deadly serious about quality sound, or need to know that you are purchasing the very best of the best, we absolutely recommend them with confidence.

Boulder have never let us down with their exceptionally well engineered preamp and amplification options. We recommend you come down and audition them for yourself and let one of our audio experts guide you through the nuances of these extraordinary pieces of hardware.
