A pure class A design transformed into a MKII model Capable of optimising sound density.

Pursuing a sound that appeals to the senses whilst creating a deep musical impression is the ultimate role of the audio amplifier. With pure class A design, the L-550AXII integrated amplifier is a refined version of the L-550AX which was itself fully restyled in 2011. The MK II model boasts improved functionality with the latest technologies equivalent to the higher grade L-590AXII such as Version 4.0 of the original amplification feedback circuit ODNF, the new LECUA1000, computerized attenuator, and a buffer circuit with discrete configuration as standard. Such features result in a model with capability of expression above its class, offering a mellow and dense sound that only pure class A amplification can create.

The L-550AXII is a mid-range integrated amplifier that increases its maturity in an attractive, functional design for music to be thoroughly enjoyed.

Rapallo | Luxman L-550AXII Integrated Amplifier

 

The new LECUA1000 computerized attenuator
A pre-amplifier circuit-integrated computerized attenuator, new LECUA* 1000, equivalent to that used in the higher grade L-590AXII model is mounted in the volume adjustment unit, playing a critical role in the pre amplifier section.The renovation was made to the buffer circuit input stage to allow smooth volume adjustment in 88 steps thereby minimizing the deterioration of sound quality. Additionally, a 3D layout has been introduced in the new LECUA1000 allowing the substrates to be placed in three dimensions. The attenuator circuit is connected directly to the amplification circuit to make the shortest signal routes and improve efficiency. The LECUA1000 has exceptional durability and is capable of controlling the changes in sound quality that may occur due to external vibrations or sound volume adjustment.
*LECUA is an abbreviation of Luxman Electric Controlled Ultimate Attenuator.

 

ODNF version 4.0 an innovative amplification feedback circuit
The ODNF* , LUXMAN original amplification feedback circuit, features a fast primary slew rate and an ultra-wide bandwith achieved through the feedback of distortion components only from the output signals. The L-550AXII is equipped with the latest version of ODNF – Version 4.0 – in which the distortion characteristics at high frequencies as well as the S/N performance have been significantly improved. Version 4.0 ODNF also features a large scale power amplifier with a parallel push pull structure where 3 stage Darlington is used. Both of these features are inherited from the M-700u power amplifier and the higher grade integrated L-590AXII. A rated output of 20W +20W (8Ω) of pure class A amplification achieves a mellow, expressive sound with a heightened sense of density with high drivability to speaker systems.
* ODNF is an abbreviation for “Only Distortion Negative Feedback”.

 

Large-capacity power supply circuit
A high-inertia power supply circuit that combines a large capacity EI core type power transformer (to which a vibration control feature has been newly added) and a large capacitor block (10,000uF x4) is an integral part of the L-550AXII. This large capacity power supply circuit supports the sound dynamics of the unit by enhancing stability at the core of the design.

 

Discrete buffer circuit
A discrete buffer circuit that is the equivalent to those used in the top end LUXMAN C-900u separate amplifier is mounted on the output stage of the pre-amplifier circuit. This protects the purity of the audio signals whilst simultaneously enhancing the drive force for the power amplifier.

 

Low impedance transmission
The large capacity, low resistance speaker relays are connected in parallel in order to transmit the powerful drive force that is generated by the high inertia power supply circuit and the large scale output circuit without loss. Connecting directly to the speaker terminals in this way significantly improves the damping factor from 160 to 200.

 

Proprietary technologies
The L-550AXII is designed using proprietary technology and customised parts to optimise the sound quality of this integrated amplifier. For example, the round pattern board enabling smooth signal transmission, and a Beeline construction configuring the optimal parts locations and the shortest signal routes. In addition to this, the loopless chassis structure minimizes the ground impedance increase.

 

Customised parts making sound quality the priority
Original LUXMAN OFC wires are used in the internal wiring of the L-550AXII achieving a smooth signal transmission due to the spiral wrap shielding on each core and the non-plating process on the core wire. The L-550AXII is designed introducing many custom-built parts and sophisticated technologies including newly developed high sound quality, low height block capacitors.

 

Abundant functions
The L-550AXII is equipped with a fully-fledged phono amplifier that is compatible with MM/MC cartridges. The front panel features multiple functions such as bass/treble tone control, LR balance adjustment, a pre/power separation switch. A loudness function interlocking with the sound volume is operable by the remote control.

 

Improved operability and functionality
The front panel features a newly designed, highly visible meter panel that expresses the identity of the MK II model with a ‘pointer type’, LED lit analog meter. The tactile machined aluminium control knobs enable greater accuracy of selection.

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!

 

Think you have a better price from someone in NZ (authorised dealer)? Call us, we’ll see what we can do.

 

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.
