CONVERSATIONS WITH COLIN / QUAD: 4-Pin DIN plugs to construct an interconnect for 33/303

Dear Colin, I’ve ordered a pair of 4-Pin DIN plugs to construct an interconnect for a Quad 33/303 system. Do both the channels need to be individually shielded, or is crosstalk not an issue here, and one could use something like this with just an overall shield? http://www.van-damme.com/14.html Failing that, can you recommend a really […]

IMPEDANCE: How to measure it?

Dear Colin, Zero autoformers; how to measure impedance please? I got a pair of Speltz zero autoformers recently but when I measure the total impedance, my multimeter sees only 0.4-0.6 ohm no matter what I do. It seems the multimeter could only read the DC resistance from the autoformer itself but not the total impedance […]

CONVERSATIONS WITH COLIN: Is material now the limiting factor perhaps?

Hello Colin. From reading your very cogent and helpful answers to those questions here I appreciate that you take the design of power supplies very seriously.

PS AUDIO: Infinity IRSV + Genesis Technology’s Gen II

Golden opportunities don’t often come our way but, when they do, we should grab them. Life’s short enough as it is. One of our HiFi Family members had emailed me a few weeks ago asking if I knew anyone that might be interested in owning a pair of Genesis Technology’s Gen II speakers. He was […]

CONVERSATIONS WITH COLIN: Why sell an under-optimized item that can be easily improved upon by the owner or a modder?

Dear Colin, If audiophile grade feet, power cords, and fuses can really improve sound quality, why don’t high end designers/manufacturers just incorporate these audiophile grade components at the time of build? Why sell an under-optimized item that can be easily improved upon by the owner or a modder? I guess you don’t do that at […]

Hi Colin. To what extent – if any – does marketing influence your designs? It has ….. for a few things. I’ve not really taken much notice of marketing and to be honest, if an audio business is run by money grabbing twits like those I’ve met in the past then … no thanks. I […]

CONVERSATIONS WITH COLIN / ELSDON – WONFOR: Boutique brand, or mass-market?

Hi Colin. First. Congratulations on rising phoenix-like from a difficult time with difficult people! From what I have read my impression is that you are intent on keeping Elsdon Wonfor Audio small; a boutique-brand if you will.

CONVERSATIONS WITH COLIN: Equipment break-in. Fact or fiction or a combination of both?

Hi guys. Is there or will there be an ‘official’ Elsdon Wonfor Audio policy on this. Here’s my view. I’m an adherent to the psychological theory of so-called break-in; it’s simply one’s brain adjusting to a new piece of audio equipment. I also like to compare it to the ancient therapy of acupuncture; break-in apparently […]

CONVERSATIONS WITH COLIN: Ideas are stolen everyday by people that could not imagine nor design anything new

Dear Colin, Can you tell us a little – or a lot if you wish – about the Integrated Amp design you are most proud and why please? The Claymore come to mind – the Inca Tech Claymore – it was designed on a whim for a US based company that never came back to […]

CONVERSATIONS WITH COLIN: External power supplies

Hello Colin. I seem to have read somewhere that you feel that external power supplies for audiophile equipment Is really an irrelevance if the original power supply design has been correctly implemented.

COUNTER-INTUITIVE: Yes … I’ll take the battered, dodgy-looking preamp please

Not my first rodeo! I’ve been the industry for a while and been taken behind the scenes of quite a few makers. The backroom people and not always males either are generally fairly approachable with only the occasional massive egos you read about. And the point of this is, err what? Many of them use […]

PS AUDIO: The next time someone messes with your creation, it’s ok to take it personally.

Paul McGowan: I came into the sound room to play something yesterday and it didn’t sound right.  After investigating I discovered someone had moved one of the speakers for some reason or another.  I was angry and took it personally.
