Latest News, July 12, 2017

On June 23 the UK voted to leave the European Union, as a result the British pound has been declining in value week on week against the Yen (and US$ and Euro), unfortunately we buy a lot of our specialised parts in these 3 currencies, well, all of them in fact, so unfortunately we will be raising the prices of all the electrolytic capacitors on September 1, 2016 to reflect the considerable increases in cost we are facing.

However, since most of you will be buying in one of these three currencies there is not a real increase as such.

The tables below show the new prices, as the Pound keeps its slow slide in value, I unfortunately expect another price increase before the end of 2017.

Introduction

In September 2014 we started releasing our new range of exclusively designed and manufactured electrolytic capacitors. We have a close working relationship with Rubycon in Japan which is allowing us to experiment with different materials and manufacturing methods, this is proving crucial in helping us develop the best sounding electrolytic audio capacitors possible, culminating in the development of the replacements for the famous Black Gate capacitors.

The first types to be made available are the standard ‘Audio Note (UK)™ Electrolytic Audio Capacitor’, which were closely followed in October 2014 by the ‘Audio Note(UK)™ KAISEI Audio Capacitor, the AN KAISEI will be available in a standard polarised and a premium bi-polar or non-polarised version.

Overall we will build a complete audio capacitor range for each quality level needed initially to primarily make our own products, but also to allow DIY customers to improve their own designs with either the Audio Note™ Standard, Audio Note™ KAISEI polar and Audio Note™ KAISEI bi-polar/non-polarized, and eventually the Audio Note™ Black Gate replacement range, which should also be available in polarised and bi-polar versions.

Here is a list of the eventual range for each version, Standard, KAISEI polarized and KAISEI Non-Polarized/Bi-Polar, values available are shown separately below with prices and dimensions.

Needless to say, building up an inventory of this many capacitors will require not just a very serious investment, but also some considerable time to prototype, audition, order, produce and deliver, so please do not order anything on this list unless it is also priced up on the lists below.



The Audio Note™ Standard Electrolytic Capacitors

Even though these capacitors represent the starting level in our new range, we have found them to provide considerably better sound quality than any other currently available high voltage electrolytic capacitor, from any manufacturer. They achieve this excellent level of performance by combining a high quality electrolyte with the best available standard paper and a specially developed foil. The result is an electrolytic capacitor of exceptional quality and price, suitable for use in any high voltage power supply Audio application.

As they become available, the Standard Audio Note (UK)™ Electrolytic Capacitors will be introduced in all Audio Note(UK)™ finished products from Level Zero through to the lower Level Three (the power supplies of the higher Level Three products along with the Silver and Silver Signature models will be equipped with the KAISEI electrolytic capacitors).

A range of low voltage capacitors using the same materials and construction has also been developed, which allows us to offer a wide selection of competitively priced, high quality electrolytic capacitors under the Audio Note(UK)™ brand.

The Audio Note™ KAISEI Audio Quality Electrolytic Capacitors

The Audio Note™ KAISEI range has been developed over the past 4 years in collaboration with the engineering team at Rubycon (of Black Gate fame). Whilst working on our top of the line Black Gate replacements (which we should start releasing toward end of the second half of 2018 or hopefully earlier) we realised that it would be possible to put together a range of more affordable electrolytic capacitors that use all of the same materials as these supreme components (the same special electrolyte, foil and construction quality) apart from the hyper expensive and extremely difficult to produce Graphite impregnated paper, so the only difference between the KAISEI capacitors and the forthcoming Black Gate replacements is that the paper is not graphite impregnated in the KAISEI, otherwise they are the same.

The first Audio Note™ KAISEI range has been available since late September – early October 2014 and started with the following 4 values, we will add a 220uF/500 volt version late 2015 plus bi-polar versions of the 22uF, 50uF and 100uF, so the entire range of KAISEI capacitors will be available in both polarised and non-polarised (bi-polar).

As with the Standard Range we will be adding even more values over the next few months, so look out for further information.



The Audio Note™ KAISEI Low Voltage Electrolytic Capacitors



Pictured above are the first of what will become a wide range of KAISEI low voltage capacitors, they will all come in two versions, standard polarized and bi-polar, the bi-polar being the premium versions sonically and of course in terms of price.

100uF 100 volt Polarized Radial 8mm H 26 mm, W 15 mm £5.50
100uF 100 volt Non-polarised Radial 8mm H 35 mm, W 18 mm £11.00
220uF 100 volt Non-polarized Radial H 40 mm, W 25 mm £30.50

10,000uF 63 volt Polarised Snap in H 60 mm, W 35 mm £68.50


We are adding more values to the range in October/November 2017.





We intend to expand the KAISEI polar and bi-polar ranges as quickly as possible, one, because the polarised versions replace the low voltage versions of the Cerafine and the Silmic in our own products, as we can no longer get in all the values we need and, two, because both the KAISEI versions sound far better than either the Cerafine and Silmic they will be replaced as we get the KAISEI values needed in stock.



Forthcoming Audio Note™ Black Gate Replacements

The latest news is that we now appear to have a repeatable supply of the carbon impregnated paper, so progress has been made and we have received samples of the WKz equivalent 100uF/.500 volt and are in the process of running them in before listening to them seriously, all listening tests clearly show that, as expected, the samples are clearly of comparable quality to the original WKz Black Gate, slightly different tonality which is to be expected given that the paper is no exactly the same as before.

More to follow

It is perhaps pertinent to clarify the situation surrounding the Black Gate capacitors, Rubycon has not made these since 2006 and they are therefore not available, I should warn you that there are LOTs of fakes around, it is comparatively easy to make fake Black Gates, all it requires is a printed sleeve that looks like an original Black Gate, so except from one or two outlets who stocked up before they were discontinued most Black Gate capacitors offered on eBay, Alibaba and other auction sites are fakes, especially those coming from sellers in in South East Asia, so be very weary of “cheap” “genuine” Black Gates on offer from places like China, HK, Taiwan, Thailand, Singapore etc. they are most likely fakes.

For the past 7 years Audio Note™ has been working with Rubycon to design and make Audio Note™ branded Black Gate replacements, these will not be exact copies of Black Gates as such, but they will represent what we consider to be a further development of the Black Gate technology, primarily through improved materials but also by combinations of materials with the main focus on sound quality rather than purely measured performance, I think it is important to stress the fact that we at Audio Note™ still consider the Black Gate the finest sounding electrolytic capacitor ever made and we are therefore keen to reinstate and hopefully improve upon this level of quality before our internal stock of original Black Gates runs out.

That is really all there is to say at this time.
