|F A Q|
In this page, we don't teach how to make good amplifiers nor what makes Lavardin Technologies amplifiers sound so good : we never do. We just give some advices on how to improve a set up and also give some replies about our amplifier's behavour.
Are Lavardin Technologies amplifiers capable to drive difficult loads ?
Are Lavardin Technologies amplifiers capable to drive difficult loads ?
Thanks to their unique circuit design, our amplifiers are certainly the less load sensitive amplifiers ever made. This does not mean one could drive 1ohm speakers at max power for a techno music party all night. It means that the amplifier handles load, voltage, current and phase changes versus frequency better than any other design. This is the most important factor for quality.
Thus driving non linear or low impedances even in the critical treble area is not a problem at all. (recommended speaker impedance remains 4-8ohm).
What kind of speakers is the best match ?
Any GOOD speaker will suit. But don't expect the amplifier to balance any defect of the speakers. Bright speakers will remain or appear bright, just the way they are and they always where. To our point of view, choosing speakers and/or amplifiers in order to balance their defects is certainly not the best way to quality : "when the Pizza has too much salt, putting sugar in it will not really "improve"....
Lavardin Technologies amplifiers is the natural choice when it is about driving very demanding transparent and revealing speakers like QUAD ESL, Magnepan, Orthophase, ...
My speakers are too bright, what can I do ?
This is one of the big problem of today's speakers. A brighter speaker will appear "more clear", "more open" and "more detailed" than its competitors, thus it will sell more. More and more customers have dull amplifiers (poor design tube amplifiers) : bright speakers will help to balance the sound. Now, what ever the reason, if is it too bright something has to be done to improve the situation. You can try these suggestions, one by one to identify the most interesting ones in your particuliar context.
Model IT, Model C42 & C62 make some little noise even after switching off
When switching on, temporization relays produce a click noise and then sound appears : this is normal, the amplifier requires these few seconds to stabilize.
How long does it take to burn in a Lavardin Technologies amplifier ?
There is no need to burn in a Lavardin Technologies amplifier once it has completed the factory final test.
How long does it take to warm up a Lavardin Technologies amplifier ?
Thanks to our exclusive technologies, warm up period is very short where classical designs (tubes and solid-state) require very long period of several days to reach their own maximum.
Meanwhile, the quality of the complete hifi system can greatly be improved after a few days when the amplifier is kept switched on : this is due to the warm up period of speakers and classical speaker cables that is much longer than for Lavardin amplifiers.
Mains live polarity / red point
Mains live polarity, that means pin of the IEC socket on the amplifier where the live is connected, makes a huge difference in the sound quality.
Should I use power conditioner and high tech mains lead ?
Most of the power conditioner and other "filtering" devices are designed to provide a certain immunity to adverse signals, voltage and current. Manufacturers are happy to demonstrate the effect of their filters. This kind of protection is more than necessary when it is about dental surgery electrical appliance !!!! Concerning your hifi system, unfortunately, most of what they do is the reverse of what could be beneficial for the sound. A Hifi system is not a piece of hospital electronic gear. This comes from wrong understanding of the problems that should be solved. Now, when this kind of equipment is used with traditional hifi gear, it brings some effects and some times it is not worth than any thing else : it makes somes changes. But does it improve the sound ? Definitely, if you own a Lavardin technologies amplifier, use our given with mains lead or our Model CMR150 mains lead and remove (unplug) ALL of these snakes out of the set up : the result will be obvious to your ears. "No one chooses a Ferrari because it can pull a traylor".
Is it worth bi-cabling speakers ?
Bi-cabling speakers implies using double quantity of cable. Now, if one pays attention to cabling, this implies one is aware that cabling can reduce musical quality.
How to optimize single cabling of the speakers ?
With speakers having one pair of binding post per drive unit, one binding post is used to connect the cable from to the amplifier, then straps send the signal to the others.
What is the best rack to put the amplifier ?
The supporting board of audio components intends first to connect the component to a static and steady physical reference and second to be itself as neutral as possible.
For these reasons, avoild any stand made completely or partially with :
To our point of view, combinating minerals with metal with rubber and with every thing else passing by, is not a demonstration of know how...
NEWS 2013 : The new and improved version of Lavardin Technologies hifiracks is now available under the brand name K-rak
These racks are hand made for us by the best woodwork experts in the "Pays Basque" and the "Anjou". Nothing exotic.
They weight much, 38Kg for 4 tears, they are made of true high quality materials and cost more than traditional hightech hifi stands using glass, metal tubes, carbon fiber, aluminimum or assembled solid wood bits ...
Should I use cones, rubber feet or springs under components ?
It seems every body has forgoten about the story. In the late 70's when Gilles Millot (famous speaker and driver designer) first presented spikes under speakers, the tip was facing a wooden floor....
The spike is only one part of the system : the part that is easy to sell and ship ....
Spikes and cones tips must face a damping / spreading material like plywwod.
Then, only can the spikes behave as a "large bandwidth" and "omnidirectional emitter" of energy in the dissipating material, thus allowing minimum energy return to the component through the spikes.
Only if you have a thick plywood plinth under components, it is worth to try what happens with cones or spikes.
Most of the rubber feet, springs or inflating devices are no useless for quality : mostly good enough to provide a less disturbing sound balance in a poor sounding system.
Does plywood also improve speaker's balance and micro-dynamic ?
The problem is very much the same as with components. The difference is that some parts of the speakers actually generate vibrations. For the same reasons, decoupling materials should be rigid and damping to allow spreading of the vibration's energy. Again the best material is plywood... A good thick plinth of plywood where to spike a floorstander speaker is a must. Additionally, spikes won't scratch the floor any more. Same applies under stands of bookshelf speakers. Additionaly, one can put plinths on top of each stand. If speakers are also on spikes, it can be also interesting to keep the spikes under the speakers ....
There is only 3 feet under Lavardin Technologies amplifiers. Why ?
3 feet is the guaranty that each foot will receive a constant pressure what ever is the flatness of the support. With 4 feet and a non perfectly flat support, one foot can remain unloaded. They are made of specific hard neoprene rubber to allow at least good results even in the most adverse environment.
