   MAGAZINE REVIEWS

Wychwood Audionics's F3 System wins Hi-Fi Choice 5 star award

Those adorable people at Hi-fi Choice have had their mitts on our beloved foo-free filters and it seems they liked them:

"produces an exceptionally capable performance"

"none of this gain in refinement comes at the expense of dynamics or energy"

"There is plenty of bass impact and none of the timing or sense of attack that the Naim review system excels at is blunted or removed"

"this is a very clever and well thought out product that delivers on the promise of improved performance at a very competitive price"

"If you want an extremely capable and flexible mains treatment solution and you don't want to spend a fortune, this is by some margin the most effective solution I have seen."

Wychwood Audionics's F3 System wins Hifi Critic Best Buy award

We were approached by industry legend Paul Messenger at 2015's NW Audio Show, and asked if we'd like to supply units for review in Britain's only truly independant hifi magazine - Hifi Critic (no adverts, no industry sponsors, no vested interests...).

One snapped-off arm later and the first review was published in Volume 10, No.1.

Paul evidently liked what he heard, finding our "modern approach" yielded a "lower noise floor" and so forth - awarding us a coveted "Best Buy"!

 

  ABOUT US :

We're a small British company established in 2007 and based in Lincolnshire.   We specialise in high performance, high value mains power treatments.

The core of our range are our high-current, filtered mains distribution units - termed Foo-Free Filters, or F3 for short.

What is "Foo"?   "Foo" is any sketchy pseudoscience misused in marketing!

We don't like foo so we research the effects of mains problems, experiment with valid solutions, build many prototypes and test them in real world systems.

F3 is a flexible, modular system:   F3 Prime & Lite provide distribution and 1st-tier protection  -  F3 micro adds versatile 2nd-tier immunity to locally-generated noise.

Our products are UK made - top quality materials are used: alloy cases, polycarbonate fixtures, overspecified components &c to ensure top performance and long life.

No shortcuts are taken - all components are fully safety compliant, and all safety features incoporate significant margins or back-up redundancy.




Why do YOU need F3?


This diagram illustrates how Wychwood Audionics 2 stage F3 system works

The effects of mains problems vary from poor sound to wasted power, noisy transformers and even equipment fires!   You may not know you have a problem until you treat it - but few households or hifi systems are immune.

1.   Electricity leaves the power station in good shape but industry, data transmission, radio, dimmers, thermostats, even your own hifi, TV and computer all add noise to the power supply.
The Filters in F3 remove this noise.

2.   Mains power is prone to surges caused by substation switching, storms, other users or industrial machinery.   Surges can damage your equipment, corrupt data - even start fires.
The Surge Arrestor in F3 MDUs protects against this.

3.   If a fault develops in your equipment you rely on a slow old-fashioned wire fuse for protection.
The RCBO circuit breaker in F3 Prime trips in milliseconds  -  it's a life-saver : avoiding electrocution and preventing fires.

4.   Some competitors rely on current-strangling chokes and PCBs, others add costs with empty gimmicks.
F3 eliminates unnecessary components to maximise current flow  -  no gimmicks, no hype - just value and performance!

All this safety, performance, convenience and quality comes at a great price :  

Similar products from competitors cost nearly 3X more for fewer features & poorer specs!

  Unsolicited feedback in our customers' own words:


“F3 arrived safely on Saturday.   I don't care if I'm deluded but my system has never sounded better!

“I received my F3 last week and am very happy with it.   It was a replacement for an IsoTek unit ... very happy to say that I actually perceived an very audible improvement with the F3 over the IsoTek unit ...!”

“...purchased it for my second system ... LED TV, Sky HD box, home cinema receiver, SBT. I turned it on ... bloody hell our TV picture has drastically improved - I mean seriously increase definitions / sharpness of the images and colours look more vivid. This was not at all subtle and i reckon you should try and measure / quantify these things for marketing as it is drastic. ... Keep up the great work.”

“...with the F3 in situ I'm hearing a lot more subtle detail at the leading edges of music - reverb, little bits of percussion, bits of stuff way in the background. Also the timbre of instruments and voices seems more defined and sharper but not in a harsh way.”

“...I am very chuffed with the F3, the overall improvement it has made to the system was very noticeable and lifted the whole sound to another level.”

“...blown away with the build quality of this unit.   It really is a triumph at this price point ... What I heard was awesome ...   I seriously couldn't see why you would bother with anything else.”

“... so value for money here and all i can say is that when placing my lugholes next to tweeters they have never been so quiet ... Everything is clean and not in a sterile way.   Now when the mags do their awards this should be in there.”

“...the hifi sounds better. There's more detail, bass sounds better defined, there's more bite so to speak on things like guitars...”

“Pretty sure in a fight between a Hughes Apache and an F3 the little black box would win! I'm gonna order another few to keep beside the bed incase pesky burglars come calling!”

“Hi Paul, just to say thank-you for the F3 Prime ... All sounds fantastic with my new MBL amplifier. This is it for me - no more upgrading!

“I am very chuffed with the F3 the overall improvement it has made to the system was very noticeable and lifted the whole sound to another level.

“Very impressed by the quality of construction and initial impressions re performance are very positive. There's definitely greater clarity to the sound.

F3 is awesome, great build ... great upgrade!”

“I have changed a fair bit of my system recently so doing A/B stuff was difficult. Until my pal brought down his valve phono and transformer that is. Last time he did that there was hum like hell. This time? Silent as as dodo's fart! ... And does it affect the music? You bet it does!”

“...Have had it in my setup for a while now.   Well-made kit - highly recommended.”



  FAQ



►   Will F3 stop my system popping and clicking?   It will help, but may not stop it altogether.   These noises are usually caused by thermostatic switches operating (e.g. fridge, air-con, room thermostat etc.), and need a snubber installing across the switch by a trained professional.   A "Spikey" inserted into the same socket as an offending fridge or air-con may help.

►   Will F3 stop my transformers buzzing?   Possibly, but in most cases transformers buzz due to 4 main causes: underspecification of the transformer for the voltage encountered, underspecification for the current drawn by the device, magnetostriction due to DC offset in the mains supply, or damage to the transformer.   All require different solutions outside of F3's remit.

►   Will F3 change the sound of my system?   Often, but usually subtly - typically bass becomes tighter, faster and deeper, midrange becomes more articulate and colourful tonally, and treble is cleaner and more extended.   The one that may have the biggest impact on subjective sound is bass - because it will often go a little deeper, it can occasionally tip speakers which are marginal over the point of overdriving the room.   If this happens, the speakers can be moved further into the room away from rear and side walls, or have their ports partly or wholly bunged (use porous foam or even an old pair of socks!).

►   Can I use the circuit-breaker as a switch?   You can, but it's preferable not to as it's not designed for the repeated wear-and-tear of such use - it should trip rarely, if at-all.   If you need a switch on the unit, we can build you a bespoke unit to your specification - please drop us a line by email

►   Can I have a home demo?   We keep our prices low by building a product that's guaranteed to provide excellent functionality, safety, build and performance, and also by keeping our costs as low as possible.   Home demos cost a great deal in wear-and-tear, damage, loss, theft &c (mostly thanks to the "efforts" of parcels-carriers), so we do not offer this facillity.   Our products work well - we promise!   If for any reason you're unhappy with them - we're here to put that right!

►   The bulb in the surge-arrestor module is flickering, is something wrong?   No, nothing's wrong.   The bulb is a neon type which, as it ages, absorbs some of the gas in its tube onto the electrode surfaces, causing the glow discharge to become unstable, causing this flicker.   Memorise this and impress people at parties.

►   The bulb in the surge-arrestor module is extinguished - what's up?   You may have a power cut, a fuse upstream of your F3 may have blown, or the surge module may have reached the end of its life protecting your equipment.   If you still have power to your equipment, then it is the surge module that is no longer working.   All is safe and well, and you should return your F3 to us for replacement of the surge module at cost (a few Pounds + P&P).

►   The RCBO keeps tripping - why?   It's likely that something connected to the F3 has a potentially-lethal fault - do not touch any connected equipment - switch off the supply to the F3 at the wall and disconnect equipment from it.   Have your equipment checked by a competent, trained professional ASAP.

►   What leads should I use?   Any that are appropriately rated (240VAC / 13A in the UK) and properly safety-certified.   We recommend and can supply Supra LoRad (see above) as they offer great value, lifetime corrosion-resistance, full screening and are fully compliant with all existing safety standards.

►   Can F3 supply enough power to my system?   Yes.  

►   Really?   Dammright!   It's good for 16A / 3.5kW continuous - the maddest hifi systems may hit around 6A / 1.5kW momentarily during transients at certain frequencies if you play your system at authentically hearing-damaging levels.

►   What's the green binding post for?   It provides a low-impedence link to Earth - this can be used to ground equipment like turntables and phono stages.   It absolutely cannot and must not be used as an alternative route for mains Earthing!   Death is just one potential side-effect of doing so...

►   Is there a fuse in there?   No.   UK mains-leads are fused, so here's no need for yet another fuse in the F3.

►   How do I clean it?   A rub over with a VERY lightly-dampened cloth - then leave to dry for an hour.   Don't use solvents and cleaning agents, nor abrasives or polishes.
