TOPPING A50 Desktop Headphone Amplifier

$399.00 inc GST


The Topping A50 is an efficient and affordable sedentary headphone amplifier.

Its careful design makes it an ideal ally for any audiophile wishing to enjoy a rich and clear headphone listening experience. The amplifier is Hi-Res certified, a label that guarantees a very good sound quality.

Description

Balanced / Single-ended connectivity
For its connectivity, the A50 is both simple and very efficient. It integrates a single stereo RCA input but has 3 headphone outputs, one of which is balanced on a 2.5mm jack connector. A stereo RCA line output is also available on the back of the unit.

 

Aluminium case
The components of the A50 Topping are hidden under a beautiful and robust CNC machined Aluminium housing. It is also designed to effectively dissipate the heat released by the power supply and PDOs.

 

Digital volume
The A50 scans the position of the volume knob and transmits the data to the JRC1195 controller for a precise adjustment of the volume level. This chip also provides a perfect volume balance between the left and right channels.

 

AOP
The amplifier includes a pair of LME49720 PDOs mounted on a DIP8 bracket. It is therefore possible to easily replace these PDOs to adapt the sound reproduction to your listening experience.

 

Regulated power supply
The power supply circuit of the A50 is stabilized by low noise TI TPS7A33/47 linear regulators. These high-performance chips provide clean and stable power to all A50 circuits.

 

A50 Headphone amplifier + P50 Power supply + D50s DAC Association
The Topping A50 completes the range also composed of the P50 and D50s. The combination of these products is ideal and allows you to benefit from a complete and efficient system. The D50s DAC allows efficient digital-to-analog conversion, supports high-resolution files and allows Bluetooth transmission. The ultra-low noise regulated linear power supply P50 will provide the A50 and D50s with an extremely clean power supply, allowing them to reach their full potential.

Why buy from us?

Rapallo is an independently owned New Zealand company and with more than 15 years experience, we offer you both technical expertise and superior service.

Rapallo is fully authorized to sell products by all of the manufacturers listed on our website and in our store. In most cases we are more than a reseller, we are a direct dealer who also receives training and where possible we personally test products we sell.

Authorized dealers like us offer peace of mind. Rapallo

  • meets manufacturer’s standards, from sales to service, in order to receive authorized status.
  • often receives training directly from manufacturer representatives and shares that expertise with you.
  • provides  support for all the products they sell.
  • ensures that manufacturer warranties will be honoured.
  • buys directly from big brand manufacturers and guarantee you buy NZ new, (no grey imports or parallel imports).

The Internet is an incredibly convenient information source and a wonderful way to find savings on the products you want. Protect yourself online by buying from authorized dealers, with genuine feedback and reputations.

A price too good to be true, usually is.
If you’ve ever searched for a product on a shopping engine (such as Priceme/Pricespy) you may have asked yourself, “Why are some stores charging so much less than other stores?”

Our customers often share these stories with us, so we thought we would share a few with you, in hopes that you don’t fall prey to any of these unscrupulous sales tactics.

  • Goods may be grey market/parallel imported. They may state that the product includes the manufacturer warranty, but not tell you that the warranty is valid only in Europe, Japan, or South America, and NOT in NZ.
  • You may be asked to buy an expensive extended warranty. In many cases if you do not purchase the warranty, your purchase will be denied. (The product is now out of stock, your card does not go through, etc.)
  • Included parts may be sold to you separately. Some resellers will open boxes and charge extra for parts that are normally included by the manufacturer.
  • Hidden charges which don’t show up until your credit card statement arrives, these charges only show up when your credit card statement is sent to you.
  • When something goes wrong, faulty, late delivery, doesn’t matter how many times you try to email, they don’t get back.
  • There are so many scamming online sellers today, “buyer beware” protect yourself!

Concerned About Fraud?

The internet has become a more popular source for online shopping, regrettably we have seen more and more instances of fraud affecting online shoppers. Companies trading under many  different names, loading warranties and charging for them as extras when often they are included from the manufacturer. Parallel imports or personal imports where the NZ supplier refuses to repair when things go wrong is often alarming to the unsuspecting purchaser. Inflated freight charges, customs and GST at the border are often forgotten as a buyer is tempted by a lower price. Constantly we hear all these stories, once bitten it’s all to late looking for that refund or replacement. The stories are outrageous at times, customers from Trademe and ebay with no place to turn, time consuming and very frustrating….

So how do you protect yourself from online fraud?

  • Buy from an authorized reseller. If you are at all suspicious, contact the manufacturer directly and ask if a company is authorized to sell their products.
  • Make sure you get a company invoice with GST clearly marked.
  • Make sure you buy from someone who has a phone number and an address on their website, not a P.O.Box number
  • Read customer feedback, you can usually tell if it’s genuine or not.

We hope that you will become our next happy customer. And we promise to offer you superior service before, during and after your purchase.
