Our latest blog post can be found at ABCaudio, on the subject of trust and decency in the audio industry (tl,dr: there isn't much). It contains some interesting recent history as well as our explanation for our use of fluffy audio-prose...

This is a test mule for a new amplifier by Colin Wonfor in a scrappy project box (the amp is in the scrappy box, not the Wonfor). It's only managing about 18W class A, and that much again in A/B due to a lack of serious heat sinks. But it keeps doubling down as impedance halves, to one ohm...

EWA audio Interconnects; the IC-25 is a state of the art expression of cable design and execution. Featuring extraordinary pure conductor cores in a litz arrangement, encapsulated as part of a complex coaxial design. Superb measured performance is guaranteed thanks to masterful cable geometry...

I will attempt to explain to explain the EWA loudspeaker cable range, with my apologies if I am not clear! We have: LS-25, LS-40, LS-50, LS-80. EWA cables look very similar to each other, so they are being visually re-refreshed end of September/October 2020 - partly to look more professional...

The first EWA USB interconnect, this has been a long time coming! Designed by Colin Wonfor to be the best high performance cable possible. Available at ABCaudio (just the first few pre-production items), until the main manufacturing run arrives in September. I'm using one now between an SOtM...

The new IC-25 interconnect from EWA (Elsdon & Wonfor Audio) is now in stock at ABCaudio. A complex and interesting design which features a revised conductor and lightweight, low mass RCA plugs, plus unique insulation material only used by EWA and a silver braided screen. IC-25 is carefully...

A class integrated by Colin Wonfor: Five watts SECA (single ended class A) then twenty five A/B. Total 30W RMS output. Superb sounding amplifier complete with USB input (inbuilt DAC) and line inputs. This is the last of the pre-production amps and it has been mine for 'testing' for almost a...

Well, not his personal one... but the one he has designed and built! The name 'Claymore' and 'Colin Wonfor' will forever be inextricably linked. The Inca Tech Claymore is still brilliant a amplifier design, and many are working perfectly to this day - some being forty years old now! They are...

EWA LS-25 is available at ABCaudio.biz. A blank slate design by Colin Wonfor, whose previous work for Tellurium Q won accolades, EWA LS-25 is a real development of his own design concepts. EWA cables are all designed to be immune to external noise, to not generate any RFI itself, and to...

Thank you Glenn for allowing us to use your lovely write up on the Q20. Hi Colin That was a most unexpected phone call Saturday afternoon but a very pleasant one and it was great chatting with you . So as promised I thought I would drop you a line and let you know my first impressions of the...

Demo is the wrong wording, these amps have only been used in my PIT (workshop) I am having a tidy up. First a Claymore 50W/Ch 8R 100W/Ch 4R Phone MC & MM etc see more:- https://www.elsdonwonfor.com/product-page/claymore-integrated-amplifier Next Q20 Power Amp :-...

...is finally back in production, thanks in large part to keen enthusiasts paying up front to finance production. 20180222_153029 by Alan Brown, on Flickr We are hoping to ship to our pre-order customers by the new year, although we cannot commit to that (it's in the hands of several...

OK got bored just finished a "Twin SECA Headphone Amp" It has two Headphones out 5W max each Two DAC inputs and two line in inputs. HP 1 can see inputs DAC 1 and Line 1 HP 2 can see inputs DAC 2 and Line 2 Ideal for couples who hate each others music. PIC's soon.

As some of you know, Elsdon Wonfor LS-25 remains out of production due to high costs. Now that Colin has retired from full time work in audio, we have been looking at how to produce this very fine loudspeaker cable again. Working together with EWA, ABCaudio hope to enlist support directly from...
