    DIY Interconnects

    Well Dave, perhaps some people can relate measured IC characteristics to a specific sound but unfortunately, I'm not one of them - for some strange reason, I did expect the $s spent on Audioquest, MIT, Chord, etc, etc cables to sound perfect in my system but they don't - perhaps in other systems they might. This is why I say that you have to try them in your own system to see if the result appeals to your hearing, not the measuring instrument. Perhaps designing a sound system sound on component specifications is the best way of organizing things but it doesn't seem to work well in my experience - maybe this works for you, but not me.

    Ah, right 'S', I'll dig up my old DNM ribbon and add some KLEs and have a listen again and see what happens - I have a 'cable burner' coming from Hagermann soon so that'll speed things up a lot - somewhere, I have a pair of that fancy Chimera Labs wired ICs around and will unbraid them and try the simple ribbon/tape idea and give them a run too - it's rather interesting, eh! Yes, it's rather surprisingly difficult to get appropriate replies that relate directly to specific questions, or maybe just an opportunity to pass on good advice even though it maybe off topic. Mind you, the inability to read clearly does continually surprise me, especially in people from an engineering background. …showing my GOM (grumpy old man) syndrome now!

    DIY Interconnects

    I would suggest to end this interminable discussion, Silent Screamer, is to simply get a couple of bits of wire and make up some simple tape interconnects and try it out for yourself - a simple experiment - I still have some cryoed UPOCC insulated wire from Chimera Labs if you want to get fancy ...

    My opinion, for what it's worth, is the ICs are just another component in the signal chain and so are subject to the components connected and this doesn't seem to be the passive tested parameters but rather, a combination of circuit type, impedance loading, and all those intangible things that really add up to 'guesswork' Many/most of us use a combination - for example, I blended the slightly bright sound of a pair of Curious Cable ICs with the slightly laid back sound of the MSA Black Magic ICs to good effect - not cheap, unfortunately. The Morrows used to be one of the best 'bang for buck' ICs but I've recently found an IC from Germany called 'Via Blue' available from Mark Thomson (M8Audio) that has the best transparency (and not just in the mids) and the basic unbal ICs (the s1) are a bit over $200 - if this suits your requirements, a very low priced high quality IC indeed. About the original question, I still have some of that ribbon wire from DNM in England (Denis Moorecrift Audio) that has the 4 parallel conductors in a clear plastic sleeve but I didn't take to them - maybe the new cable is better - about A$40/metre and an easy assembly - the idea of tape and individual insulated wires 'a la PC Audio' is an easy & cheap option.

    Yeah, I know - just mentioned a few of the obvious choices - a very wide field and where to start is a problem. I get quite impatient waiting for the cables to 'burn-in' (most take 100 - 200hrs) and ordered one of those 'cable burner' units from Haggerman - apparently, this only takes 3 days instead of a week and a half - it'll be interesting to see ...

    What particular suggestion/method of the video are you interested in? There are so many thoughts about interconnects that it's difficult to separate the well-engineered methods from the guesswork and I think it comes down to your own perception - some people can't tell much difference between the $5 ICs from Jaycar to the 1k$ Audioquest units and other people see it as 'chalk & cheese' What sort of wire (solid, multi, silver, copper, tinned, etc, etc) - what sort of RCA plugs on the ends (again, silver, copper, brass, Expensive ones, cheap ones, etc), what sort of solder, and so on ... I would imagine that you would be interested in the particular types of ICs that other people use in a system setup similar to your own, yes?

    Yeah, no problems One thing, if you haven't already 'got started', is the need to control the bass reverb times - basic acoustics - not at all difficult but the 'terms' are a bit unusual - and you don't need to spend huge $s either. We've got a rather interesting section here on SNA that's full of useful information and another is the 'Gearsluts' site.

    It's still on hold for the moment, unfortunately - these little Betsy K drivers exhibit quite low distortion when crossed over high enough and naturally, the Lorantz drivers are also very low distortion drivers too. However, there's phase/timing problem with the 2 different amplifiers that can't be compensated by an electronic Xover so my attention has been diverted to using a dsp Xover and I'm in the middle of this now - even with help, it's slow going, unfortunately. Personally, I think if you can get high quality bass drivers that'll be usable up into maybe 200Hz+, the Betsy's can then be used with a passive Xover, altho good components at this low frequency are still not cheap. The surprising clarity of the Betsy K drivers without any fatigue is definitely worth persevering with if you listening requirements run that way. I tried them on the small baffle and am a bit puzzled at the reports about this size, even on the floor, producing bass - to me, this small baffle struggles to produce signals at about 80Hz but maybe the OB version will do a better job. Mind you, IMO, good clean bass response is the foundation of good sound reproduction (the 'get the bass right first' brigade) but this mayn't be the same for you.

    SOLD: FS: HIFIMAN HE-400I - new.

    Are these much different to the HE-400s ones? I've got a pair of the Massdrop HE-4xxs that come with those u-beaut earmuffs and curious about any difference in the sound with the 'i' and the 's' version.

    US power board

    Good info - thanks Those Sydney Tools units, or similar, are available from Middy's, L & H, and indeed our local Bunnings - sometimes under the Arlec or HPM name - I haven't seen any made as flat packs like the ubiquitous power strips but no doubt, they're probably available, complete with the RCD, etc, protections.

    US power board

    A curious thing with my Ayre mains 'filter box' is that it's used the Oz brown/blue/green insulation colours instead of the usual US Black/White/Green I'm with 'ag' on the build quality of the big ceramic US plugs/sockets - I think those ceramic US sockets have superior contact surfaces/pressure to our own AU sockets, especially our current production units - nearly all our domestic plugs/sockets are becoming 'lighter duty' devices, some are of quite 'flimsy' construction indeed especially in comparison to the US big 'chunky' things built for high current and voltages. The available China line plugs seem to be built with slightly thinner pins (or blades, as they call them for some strange reason), and hence lower contact pressure, altho they do still seem to work quite well. I've never had any problems with the familiar IEC power plugs/sockets and tried some of the China built AES sockets with 'audiophile' copper pins (no difference to 'normal' version, IMO) but the pins are actually thicker than standard, go figure! Expensive little buggers too, more fool me! There is a certain confidence to get all plugs, sockets/cable tested and certified despite the cost - I was quite surprised to find that some, if not many, of the high priced audiophile power cords either aren't certified, or even checked, I think. I checked one locally assembled and crazy priced solid silver conductor power cable and the Act/Neu was indeed reversed - it's not something you like to see on any cable, let alone one at this price - a cheap simple testing plug would show this mistake immediately It's just another reminder to us all to 'pay attention' the small details,, eh !
  12. You might have a look at the Shahinian Acoustics (Obelisk) or maybe the Sonab OA-12s - well proven designs
  13. I'm rather interested in this too - no earth connection at all?! Is it double insulated with isolated shielding too?

    DIY Power "Conditioner"

    I've used the Schaffners for some years but I think these 'oeelsafe' ones have a similar inline filtering plus added surge protection - I would presume these aren't a cheap little board ...?

    US power board

    One thing about the US plugs/sockets that may be interesting - I recently changed out the rather solid, heavily built, ceramic US sockets on a 'US made' line filter box and the Active and Neutral wired connections were "back-to-front' to our sockets I often wonder if all the US built equipment is connected this way and if the importers/retailers correct this wiring - I don't know if this has any effect on the sound at all but it's a bit disconcerting to know that a US built amplifier, for example, may indeed have the mains fuse in the Neutral line and not the Active. Just something to keep in mind ...
