Frequently Asked Questions





Which pick-up arm do you recommend?

Our turntable design philosophy was centred around the use of rigid gimbals bearing designed pick-up arms with a neutral sonic character. Many designs exist and you would best seek the advice of your supplier.

Arms with SME style fixings can be mounted directly, however other styles may require a special adapter.

Whilst other designs including unipivots, air bearing and parallel tracking arms will work they may not offer the maximum in information retrieval, however they may offer a preferred sonic subjectivity.

Typically with these types of arm, we have noticed the fluid damping they usually employ will cause high frequency roll off, giving a misrepresentation of the recorded sound. The unipivot arm supplied by Naim is an exception however and whist not offering the frequency extremes of a rigid arm does offer exceptional performance within the midrange.

Our current suggestions for manufactures would be (in no order); Dynavector - Naim - Rega - SME

Which cartridge or phonostage do you recommend?

Unfortunately, we are unable to recommend which cartridge or phonostage to purchase.
This is down to personal opinion and whilst we have our own personal favourites we will only have limited experience as to all the products available.

Some will need to choose components to compliment your existing systems.
As a rule however, as our turntables offer a very neutral foundation it would seem logical to match them with other neutral sounding products.

We suggest that you visit your local AVID dealer who will be able to give you advice and hopefully a demonstration.

What tone arm cable do you recommend?

We have little experience with alternative tone arm cables, however we are aware that they can make a significant difference to a systems performance.

You are best to consult an AVID dealer for specific advice.

What support should I use under my turntable?

All our turntable designs employ sprung suspension, keeping unwanted vibration away from the stylus and whilst the supporting surface is less important than designs with little or no isolation, there are still some factors to take into account.

Sprung isolation systems only have a limited degree of movement, otherwise they become too bulky for practical use and there design becomes compromised. As such you should take care not to place the turntable were large sudden movements will occur, such as racks on loose floorboards or insecure walls.

Ideal situations are light rigid wall shelves mounted to secure solid walls or racks onto firm or solid floors.

You need to make sure however not to use very heavy racks on thick carpet for instance as the whole structure will move at a frequency below the turntables isolation frequency and will then constantly move.

Again we strongly advise you seek the assistance of your AVID retailer should you experience any issue.

How do I use the Acutus clamp correctly?

Common to all our turntables a reflex design clamp is used.

The principle is simply to firmly clamp the record to the main bearing (slightly raised from the platter surface) then flex the record downwards into contact with the platter surface. The outside edge of the record touches the platter first, gradually working its way to the centre until the playing surface is flat.

The Acutus clamp allows the user to fine tune the amount of clamping used.

Before fitting the clamp make sure the black clamp ring is released by loosening the lower hand wheel.
Fit the clamp using the top hand wheel. This clamps the record directly to the main bearing.
Then wind down the lower hand wheel until the record is flat and without air pockets underneath.
This can be check by lightly tapping the record to listen for a hollow sound.
Remove the clamp by reversing this process.
Remember to loosen the lower hand wheel before attempting to refit the clamp.

Should you have difficulty please consult your manual or dealer.

My partner says I listen to my turntable too much!

AVID turntables make listeners rediscover their record collection, which does take some considerable time.

We have received calls from customers claiming to have stayed up all night, been bought to tears and had friends unwilling to leave. Whilst such stories are heart-warming and of comfort to prospective purchasers we would ask you exhibit self-restraint and consider others.

On the other hand "life is not a dress rehearsal"...  so open another bottle and enjoy some more...

Why don't your turntables take 12" pick-up arms?

From inception, our design philosophy stated maximum information retrieval....in the real world.

The pick-up arm is one of three elements that make up the record player. Establishing that rigid 9" arms would offer the best performance, our designs were modelled around this parameter.

Recently 12" arms have come back into fashion, claiming lower tracking distortion. However whilst in theory this is correct in the 'real world' this rarely happens and there are also the downsides to take into account.

Average distortion on 9" arms is 0.85%, whilst 12" arms are 0.67%. Some trying to impress will say this is 20% lower distortion, however this is incorrect as in real terms its only 0.18% lower.

Now add to this the downsides of higher moving mass, lower arm rigidity, higher counterweight inertia and worst of all higher distortion caused by misalignment.

Yes...in the real world rarely are styli correctly fitted within the cartridge body and most fit their cartridge using a standard alignment gauge using the body as a guide. Therefore if your stylus is misaligned within the headshell the distortion will be greater using the 12" arm as the distance from pivot to stylus is greater.

Record damage is greater due to counterweight inertia, warp tracking worse by higher moving mass and sonic degradation caused by unwanted structural resonanceís in longer arms, coupled to having oversized turntables causing more issues.

And you still want to use a 12" arm   ?

Why is the Acutus only available in chrome?

Nothing about the Acutus is done without reason, whether it be the materials used, the size, shape and even the type of paint, and this is especially true of the chrome-plated finish.

Vibration within the record, caused by the stylus, is mostly reflected from entering the platter body by our special resin mat and transmitted to the subchassis via the bearing. Because itís impossible to reflect all the vibration, some enters the platter. Spectrum analysis of the platter reveals that the vibration is mostly high frequency and if not damped will induce high frequency coloration.

Higher frequency vibration tends to travel along the surface of materials, very much like the skin effect in cables. The act of multi-layer chrome plating onto a softer substrate, in our case aluminium, performs an act called 'constrained layer damping'. This is very effective at damping the high frequency vibration with good linearity with noticeable improvements to high frequency detail and resolution. Using other damping methods would affect other parts of the audio spectrum and the usual cosmetic finish of anodising only hardens the material surface, preventing any damping and adding the resultant high frequency coloration.

A retailer recently asked; 'Why chrome, I want another finish !'
We replied; 'It will compromise the sound quality'
'Keep it chrome' he said.

Acutus is also available in Gold plate. This finish achieves the same effect, albeit less durable.

Why is the Diva platter made of MDF?

A few have quizzed this, with the implication MDF is inferior and aluminium or acrylic would serve better.
Lets start by stating that like our other turntables, nothing is without reason and benefit to the whole and final design.
It is common knowledge one of our design principles is that the motor power should be dominant over the platter mass. MDF provides a rigid platter material and the correct total mass for the motor power output. Higher platter mass can overload the motor, sending it into oscillation producing excess vibration and speed instability, leading to power supply issues. Also the record interface is our cork/neoprene mat, which reflects most of the vibration back into the record for dissipation through the clamp/bearing. The small amount of vibration that may be passed through the drive belt into the platter is effectively absorbed as MDF has a high internal damping factor, unlike aluminium or acrylic.
