Which Amp is the best for my speakers?

So you just bought that speaker you always wanted, but now, it is set up in your living room, it does not sound like what it sounded at the showroom?

It must be sales trickery! Right?

Most people abandon the fact that the amplifier you use is one of the most important things you need when driving a speaker.

I am going to use an example:

I had a client coming in on a Sunday, eager to buy a Monitor Audio Bronze floorstander, but after hearing the Monitor Audio RX8, he committed to the superior Silver range from Monitor Audio. The demo was done on a Rotel Pre/Power 200watts combination, which blew him away. Upon asking what electronics he has, he assured me that his Yamaha will do the trick, as the speaker's rated 150watts is way below his Yamaha's "rated" 180 watts per channel. 

a Few days later, I got a call, the client says the speakers does not nearly sound as good as it did during the demonstration, can I help? So I jumped into the van, armed with the same Rotel Pre/Power combo, Audioquest Interconnects, Audioquest custom made speaker cables with banana plugs. Arriving at the client, I quickly added the Power Amp to the existing Yamaha's pre-outs. Magic happened, the client was ecstatic. I proceded by then using the Rotel Pre-amplifier and cabling, where the sound just opened up so much more. Needless to say, the client upgraded to the better, newer and more powerful system, and was happy.

SO, WHAT THE WATTS IS GOING ON?

So I am not going to bore you with the technical explanations, it is time-consuming, it is debatable, it is always being challenged, so here I will follow with the easiest way to explain it.

You have a Hyundai rated at 140kw, and a Mercedes rated at 140kw. Who will win the race? Same power right? But do we take into account weight, efficiencies, using more low-cost manufacturing components vs newer technology? Mercedes will always win, it just does it better, with the same rated power. You might add, the Mercedes has more torque...which makes for the next paragraph.

You never walk into an audio shop and asks for the most powerful Wattifier. You ask for an Amplifier, which produces amps, which is the actual electrical current driving the motors in your speakers, which produces watts.


Why the watts then?

Mostly marketing really! Thank you Sony PMPO.

So how do I choose?

There is no better way to choose the right amp for the right speakers, then going for an auditioning at your local showroom. Contact your local importer of the speaker brand you have, and ask them what they would recommend.

Example, KEF would most of the times recommend you look into Primare, which powers their speakers exceptionally well. Primare also powers most British speakers very well, including B&W and Monitor Audio.

Another example will be Yamaha driving Bowers and Wilkins very well, but not KEF as much, as KEF tends to be very sharp on the higher frequencies when coupled with a Yamaha, which is naturally a sharper sounding amplifier, which is once again neutralized by the B&W's warm sound.
You would find a Focal Speaker will not work at all with Primare or Class D amplifiers, yet, enjoys Class A and AB amplifiers from McIntosh and Marantz/Denon.

Go and audition, don't just read about it, it is much more fun!

Bowers And Wilkins 600 Series

The B&W 686



The 686 is the baby of the 600 Series bunch, but doesn’t lack for the technologies and features to deliver outrageously good sound in smaller room settings. Mount a pair on a wall or stand, or simply sit them on a shelf or table for a compact stereo system or as surround speakers in a home theatre set-up.

The 130mm diameter Kevlar® cone bass/midrange is based on a tried-and-trusted B&W design, but its new fixed centre bullet helps to smooth the response in upper frequencies. Also, by setting the bass/midrange closer to the tweeter than in equivalent earlier speakers, we have improved the integration and vertical dispersion of sound from the two units. The 
Nautilus™ tube-loaded, aluminium dome tweeter, featuring a new surround material to improve spaciousness and imaging, adds needle-sharp top end all the way to 50kHz and beyond.

The improvements to the drive units in the new 600 Series make it possible, for the first time, to introduce a minimalist crossover to the range. The use of components that are fewer in number but higher in quality – hand-picked in exhaustive listening tests – reduces the degradation of the signal significantly. So, whether you’re enjoying hi-fi or home cinema, what you hear is that much closer to what was recorded.
 
The B&W 685



For hi-fi or home cinema in small to medium-sized rooms, you need a loudspeaker that doesn’t take up floor area, but whose sound can still command the space. You’ll find the 685, which can sit on a shelf, table, stand or wall-mount, an inspired choice.

Its 165mm diameter Kevlar® cone bass/midrange is based on a tried-and-trusted B&W design, but its new fixed centre bullet helps to smooth the response in upper frequencies.

The B&W 684



The extended bass response and output capacity of the 2½-way 684 floorstander make it a great choice for hi-fi or home cinema in medium-sized to large rooms.

It features a new combination of a pair of Kevlar® cones for delivering its bass and midrange. The lower cone is dedicated to bass, which relieves the upper bass/midrange unit of the duty to handle heavy bass and leads to clearer, crisper midrange than you might find in smaller speakers. The Nautilus™ tube-loaded, aluminium dome tweeter, featuring a new surround material to improve spaciousness and imaging, adds needle-sharp top end all the way to 50kHz and beyond.

Visually, a refreshed, contemporary design language and a widened choice of wood finishes allows the 684 to fit in effortlessly with any interior.

The 683 Package




The 683 Theatre is the reference 600 Series home theatre system, put together to fill large, open spaces effortlessly with the richest, most realistic sound.

Prepare yourself for the big sound experience, fronted by a pair of uncompromising 683 floorstanders and the HTM61 centre speaker. A pair of wall-mounted DS3 surround speakers provide the all-enveloping effect of sound from the rear positions, and, if there’s a scene with a helicopter landing or a bomb going off, an ASW610XP subwoofer will let you know about it.

The imposing 683 is the genuine three-way speaker of the 600 Series, with a line-up of technologies and a level of performance that defies its entry-level place in the market. For large rooms, two 683s make a formidable partnership, either for stereo hi-fi or fronting a home theatre installation.

Deep, dynamic, bottom-end power is delivered by a pair of aluminium/paper/Kevlar® composite cone bass drive units. The 150mm Kevlar® midrange handles middle frequencies with its characteristic clarity and tunefulness, but, for the first time in a 600 Series speaker, includes FST cone surround technology for extra detail and resolution. The Nautilus™ tube-loaded, aluminium dome tweeter, featuring a new surround material to improve spaciousness and imaging, adds needle-sharp top end all the way to 50kHz and beyond.
