The Top plate replacement is a straight replacement for the original stainless steel sheet. Machined from a solid alloy billet it is dramatically stiffer than the original part, whilst weighing a similar amount. Not only does this provide an accurate and stable platform from which to suspend the sub chassis but it also provides a significant reduction in the amount of energy from the motor reaching the sub chassis and main bearing. This in turn improves music retrieval.
Many have noticed that the existing top plate is in fact a stressed fit; the stainless steel original incorporates a bend to ensure that it makes good contact with the wooden plinth to reduce rattles. However, it means that the three subchassis bolts will never hang perpendicularly and require bending to ensure an accurate set up of the deck. The Tiger Paw version is completely flat. The machined studs now sit accurately and perpendicularly to the top plate; set up is dramatically simpler. The top plate is fundamental to all aspects of the LP12; the motor is mounted to it, the sub chassis is suspended from it, and it is mated to the plinth.
Top Plate components are machined to reduce standing wave formation. Each piece is designed to be inert and not act as a wave multiplier. Similarly this has not been achieved by increasing the mass of the component, which we have found to be ultimately detrimental to the overall performance of the deck.
Khan does not require any modification to the LP12 but simply replaces the original part.
The original pressed steel cross brace is replaced with a machined alloy part which is both more rigid and features standing wave reduction grooving. The Tiger Paw version will not distort when tightened and provides a rigid resonance free platform for either the Valhalla board or Lingo control board. Once again it is produced to exacting standards and a straight replacement for the original Linn part.
The sKale achieves this in three ways:
1. By placing the counterweight in the optimum position near to the fulcrum of the arm the cartridge benefits from less influence from inertia, in other words the mass of the counterweight is being moved less. This is particularly noticeable if you choose to use a heavier cartridge such as some Dynavctors, Lyras and most Koetsus. However, the effects are still quite pronounced with medium to lighter weight cartridges.
2. sKale incorporates an offset centre hole which serves to lower the centre of gravity of the mass further in line with the stylus and cantilever. The benefits of this are well documented and incorporated in to the design of many other high performance arms.
3. sKale features a unique decoupling arrangement to reduce resonance reflection within the arm. A great deal of time was spent analysing and evaluating the impact of using different materials to decouple the weight from the arm; the final choice was arrived at following extensive listening evaluation.
The key function of the Tiger Paw sKale adjustable counterweight is to allow the cartridge to perform optimally when using Ittok, Ekos and Ekos SE arms. Double click to edit
Adjustment of mass of the sKale is achieved by fitting additional discs in to the recess to the rear of the counterweight, secured by three bolts. The weight of the basic skale is 140g and the two additional discs weigh 20g and 15g thereby offering the following options;
What can you expect?
Essentially, more music from your LP12.
Specifically you can expect greater focus which harmonically portrays a greater picture of the music. Timing is engaging and intrinsic to the song. There is greater detail retrieval and a noticeable drop in the noise floor. The sound is more integrated with a seamless transmission through the frequency range.
Khan transcends where we were before.
SKale is available in either a Satin Chrome or Satin Black finish to compliment the high quality that users of these arms would expect.
Considerable development has gone in to the final product which, as with all Tiger paw products, has undergone extensive and protracted listening evaluation at every stage both by ourselves and from independent listeners. Managing the relationship between record and stylus is the essence of vinyl replay and sKale has been designed to further improve that interface.
As for the gains in sound quality these are best quantified for oneís self and should be easy to evaluate at one of our dealers; we note a deeper more tuneful bass, vocals are sweeter and more intelligible while the top end is cleaner and more detailed. These qualities are achieved by simply creating a better environment for the cartridge to do its job.

Introducing the Elevator
Elevator is a new accessory for the Naim Aro tonearm and has been designed specifically to enable easier cuing.
The original Aro is a unipivot design and was not offered with a cuing device but relied on customers dong this by hand. The ĎAromaticí was briefly available to assist with this but has not been available for many years.
Elevator is a bespoke solution designed to be fitted directly to the Linn arm board utilizing existing components. The Keel (A) already incorporates an additional locating point which needs to be drilled through. If using a standard arm board then this will require an additional mounting hole to be drilled in the same place as the original Aromatic hole.
In practice the Elevator offers damped raising and lowering of the cuing bar as in a conventional arm and features a similar pot to that fitted to the Ekos SE. The bridge can be lowered or raised to suit differing cartridge geometries and incorporates complete adjustability. The bridge it self has also been lengthened to provide additional security.
We would like to thank Peter Swain at Cymbiosis for his assistance in conceiving the Elevator and hope that it brings increased confidence and ease of use to those Aro users with expensive cartridges!

-Precision machined aluminium top plate
-Revised studs and fixing bolts

Tiger Paw philosophy
We try to design honest products to improve the pleasure you can get from your turntable. Each product has been carefully developed and manufactured to offer performance and value. We also try to ensure that it is a component that you can be proud of owning in terms of itís finish and design.
Music is such a powerful part of millions of peopleís lives, it takes us to new places and provides a back drop to memories and events, replaying great recordings with a good system is a privilege for us and with that in mind we decided to make a permanent contribution to those less fortunate in parts of the world where the luxury of replaying music is a far cry from survival needs.
With this in mind we now donate 5% of our sales to charitable causes regardless of whether you buy directly from us or via your dealer. Until the end of June 2015, this will be to the DEC (Disaster Emergency Committee) to support the efforts in Nepal following the earthquake disaster.
Akula sub chassis
Since the launch of the original Khan, and subsequent sKale and Elevator products we have received requests to look at alternative sub chassis solutions. The Keel has always been our reference and indicates the fundamental performance improvement that good engineering in this area can achieve.
However, Iím aware that the sub chassis area is one of controversy with other manufacturers and we were not keen to become embroiled in that confusion. Following several discussions and having examined some of the alternatives we set about analyzing the issue over the past 18 months.
We have taken a slightly different approach in arriving at our solution in order to come up with a product that delivers the highest level of musical performance and remains cost effective.
The first conclusion that we came to is that we are essentially trying to manage the relationship between the main bearing and arm connection (perhaps obvious). As demonstrated by the Keel, this is best achieved by a single connection; further connection points act as filters, ie, placing an armboard between the arm mount and rest of the chassis results in loss of information. However, a large piece of material between the two points gives rise to similar issues; not all materials can be machined to that shape and choice of material is critical in managing the harmonics between the two pieces. In car terms, this is the equivalent of designing a suspension component to link the hub to the chassis and then adding additional mass and shape in order to fulfill a non critical application; the ideal is to design a component that is correct for the job.
So with that principle in mind we use two pieces. One piece is the primary connection and locates the arm directly to the main bearing housing. Being a smaller assembly this gives us great choice in material and allows us to optimize that piece for itís specific role. This is the connection that drives information retrieval and musicality.
The secondary plate is used for holding the beam in place and is designed not to interfere with the performance of the primary assembly. To that end it is decoupled from the beam and acts as the carrier and suspension interface.
Lastly, to preserve the original aesthetic of the deck we attach (an original) arm board to the main beam to cover the hole. Once again we are trying to ensure that it does not interfere with the way energy and movement is transmitted between the arm and main bearing.
In order to improve the way energy is transmitted, the main bearing and arm are both located with the familiar 3 point locating patterns. The main beam has been machined to ensure that standing waves are broken up and is curved in ordered to add strength. It is made of a different material to the spring carrier which is optimized for itís specific role.
In terms of performance, we believe that it is the ultimate sub chassis that you can fit to an LP12. The Keel is without question, an excellent component; the Akula has been designed to produce similarly excellent performance. The two will not be the same and preference will play itís part here, but it will significantly out perform any other chassis that we have compared in terms of musical information and resolution. The Aro version is unique in dispensing with the original Aro mounting collar allowing direct connection of the arm pillar to the sub chassis - those who have found the Aro losing resolution at the frequency extremes will be pleasantly surprised.
Due to the modular nature of the Akula we can provide versions for Linn arms, the Naim Aro and Rega arms. As before, the Akula is available through competent qualified dealers who will be happy to demonstrate and carry out installation, or directly from ourselves.
Includes Linn arm board, sub chassis and all fixings
We hope that you enjoy the considerable benefits of a high performance sub chassis and are pleased to be able to explain to you the thinking behind the solution. We named it Akula after the double hull construction of a certain submarine; the two part sub chassis but single arm/bearing connection was a significant step in designing a component based on logical engineering principles to provide excellent and cost effective performance.
Tiger Paw Wall Shelf - VulKan
The Tiger Paw wall shelf has been designed to be an effective light weight and rigid mounting platform for the LP12, or other high performance turntable. It features a thin wall steel frame constructed to be as light but rigid as possible, and offers three or four point spike decoupling for the top shelf. The frame is finished in matt black powder coat process. In conjunction with specially imported wall fixings which provide filtering from wall vibration the VulKan wall shelf assembly has been designed to offer a consistent stable platform for a turntable.
VulKan is available with various options. The thin shelf (standard) is ideal for those using standard feet and 4 point spike decoupling. A spike is located beneath each foot and the shelf is rigid in this context. The threaded inserts are located in a hexagonal hole to ensure that they do not slip or rotate when the spikes are tightened and secured with a lock nut. Each spike is cross drilled to aid adjustment.
A thicker shelf is available for those using the Trampolin or Urika base plate which features inboard mounted feet. This ensures that the shelf remains flat and reduces warp or flex. Similarly, if you wish to use the optional 3 point spikes you should use the thicker shelf to prevent board flex.
In order to prevent the shelf being accidentally knocked the two wooden shelves feature security slots and two pins on either side of the frame to prevent accidental slippage.
