Description

The PS Audio BHK Mono 300 Power Amplifier

The audio performance and build quality of the BHK Mono 300 Power Amplifier has been refined, honed, and polished over the past half century of design work by industry legend, Bascom H. King. They are mono block amplifiers that produce 300 watts into 8Ω, 600 into 4Ω, and a whopping 1,000 watts into 2Ω. The BHK Signature 300 Monoblock designs are built upon two proven topologies: a zero-loss vacuum tube input stage coupled to a high bias differentially balanced MOSFET output. If you are uncomfortable with compromise and seek the finest performance, reliability, and build quality, the BHK Signature 300 series is a perfect fit that can drive any loudspeaker to musical perfection.

  • DESIGN – the hybrid vacuum tube/MOSFET design of the BHK Signature Amplifiers provides stunning musical performance through any loudspeaker. The Signature 300 Mono doubles the output current of the 250 Stereo, and doubles the tubes, power supplies, transistors, capacitors and resistors. The results are hard to put into words. Your first listen to these extraordinary monoblock amplifiers will likely be a revelation. For perhaps the first time you’ll discover all that has been long buried in your musical collection. You’ll know this amp was the right choice from the very first note you play..
  • APPLICATION – the BHK Mono 300 Power Amplifier is one of only a rare handful capable of uncovering music’s rich tapestry in a lush, uncompromised, effortless presentation. If you haven’t any barriers to perfection, the BHK 300s are perfect for any size system in the world, producing a minimum of 300 watts into 8Ω, a minimum 600 watts into 4Ω, and an astonishing 1000 watts into 2Ω. Enough linear amplifier power to bring life to music as you’ve only experienced with live music.

Technology

The importance of the power amplifier in the 2-channel system chain cannot be overstated, yet it’s often overlooked. It’s the rare few music lovers that truly appreciate the power amp’s critical role in preserving music’s nuanced details, because most amplifiers fail to preserve them. Overtones from plucked instruments, subtle cues defining placement, depth, soundstage width, and transient decays are often lost in the power amplifier. Suddenly revealed are the tiniest of details that now ring clear through the BHK, perfectly preserved through its low feedback, vacuum tube and MOSFET design. When it comes to musically controlling and powering loudspeakers, the BHK Signature 300 has no peer. The Signature 300 monoblock amplifier produces 300 watts into an 8Ω loudspeaker, 600 watts into 4Ω, and 1,000 watts into 2Ω, providing unfettered and unrestricted dynamics and musical ecstacy that only a rare few are able to enjoy.

 

Input Stage

A power amplifier’s input stage is a critical interface in the quest to preserve music’s essential details and vacuum tubes do it best. Hand matched pairs of Russian Gold Lion 6922s provide the perfect interface between the delicate musical transitions output by the DAC or preamplifier, transferring it without loss to the MOSFET output power stage and eventually the loudspeakers. The hybrid approach used in the BHK Signature takes advantage of the best traits technology has to offer, unavailable in traditional solid state or tube designs. While vacuum tubes are the perfect input stage, they cannot make the same claim on a power amplifier’s output. Conversely, solid state designs are correct for output stages, but suffer when used as inputs. Only a hybrid approach takes advantage of the best in both disciplines.

 

Output Stage

A power amplifier connects its reservoir of energy to the loudspeaker through a type of valve (solid state or vacuum tube) controlled by the input stage. If the input stage has done a good job of preserving music’s subtle details, textures, timing and phase information, transferring it without loss to the power stage and eventually the loudspeakers is best handled by a tube-like solid state device known as a MOSFET. Not all MOSFETs are the same, their differences characterized by their relationship with the input signal and the power supply driving them: N-types for the positive going signals, P-types for negative. N-types have lower distortion and perform better than P-types but N-channel-only amplifiers are rare. Using only N Channel MOSFETS in its output stage, the BHK Signature produces a near-perfect balanced waveform without the degradation inherent in a complementary design.

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!

 

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.
