The 24awg neotech interconnects have been running in continuously on my squeezebox for 3 days.   Just put them on the killerdac to ligthspeed connection, and unfortunately they have not hit a home run.    The top end is more pronounced than my penguin interconnects.

A few things;
- could be my dodgy workmanship
- could be the yarbo connectors
- my room has a tendency to the bright side,  any change that leans in that direction is immediately noticed.

I might change the connectors, as these yarbos are too freaking tight for my wbt's.


Might be RF. Might be grounding.

Your amps are solid state closed loop = very susceptible to RF. Your interconnects are nice antenna.

Most valve amps, especially SETs are very insensitive to it and just act like a big low pass filter.
SS amps can be a whole different kettle of fish.

2nd thing - how is the whole system grounded? Unbalanced consumer equipment (killerDAC)
can have many types of grounding configurations. Most home audio systems will have at least one ground loop
which may or may not pick up hum - it will most certainly have an effect on the sound even if there is no hum.

So whilst the interconnects are important (I've got lots of various hand made ones sitting around) it's worth remembering some of your audio is sneaking
around through / getting corrupted by various ground paths that you are unaware of.

Hey T,  I'm not running SS at the moment.

I'm running an old Radford tube amp into Tannoy golds.

And yeah, I do have a hum happening in the system.  I think it might be the amp, but am not sure.

Radford - nice amp! How are you finding the sound compared to your old active SS system?

WRT amp hum, unplug the interconnects to the amp and short it's inputs. If the hum is gone, it's not the amp per se,
but probably an earth loop.

The sgr's are cleaner, more extension, image better.

The Radford/Tannoy combo has a nice musicality, but there is some grain that I hear. Need to refresh the crossovers in the tannoys, and plan to make some cap changes in the amp.

I'll try that test with the amp, cheers.

Hay mate, I got some IC off Geoff, one pair using copper and silver, the other pair all copper with copper Eichmann plugs. I have the copper/silver in my system and a mate now has the all copper ones.

I was talking to Geoff and he has found the Neotech wire takes some brake in, it goes kind of flat sounding for a while until more hours are gained.

Maybe give the IC's some more time.

No shielding on these ICs

Hi A, I am a Tannoy fan myself and have an old pair of the entry level Saturn S8' dual concentrics sitting in my cupboard. The Saturns are not in the same league as the proper DC's but they do share the family sound.
I have heard it said (Mick Maloney and others) that all the Tannoy DC's have a bit of a spike in the mids which can add a bit of grain bit I still love the sound , as you say "very musical".
Listening with my ears :)

Hey G, things have evolved quickly, the grain has gone.  The issue was the cheapy tubes that came with the Radford.  New tubes throughout have made an incredible difference.

the other day I ordered the all copper kind, arrived yesterday.  I look forward to comparing them.

I did run them in on a second system. They weren't flat, they were bright.

Last night I changed the topology. I added a 2nd ground wire, and platted the 3 wires, with 1 of the ground wires only connected at 1 end.  Same connectors. Will see how that goes.

Following this thread closely as I'm looking to get a pair from Geoff too. How about digital cable? Can I use the IC from Geoff for digital cable?

Thanks,
William

Hay OZ, how did you go with the three braid IC's?

Oh, and what did you find with the IC's off Geoff?

The 3 braid is better, this topology is also different because I used 1 run of 20awg on the ground/neutral,  this thicker wire is connected at both ends. The other 24awg neutral only connected at 1 end. 

I forgot about geoffs ic's, they've been running in on my squeezebox on a continual loop.

I'll give 'em a try when I finish porting my tannoys.

Interesting, I have also read that a larger return path is preferred by some folk, haven't tried it myself yet.

With the ones Geoff makes, some have said that the presentation moves back a little, and I have also found this to be the case, but It's not a negative for me, just different to the other ICs i have.

Whacked the all copper Aurealis interconnects on, and they definetly sound better than my DIY cables. The Eichman plugs would have a big part in that.

Good value interconnects, that don't cost too much more than the cost of the parts.

Geoff has send me his newly developed IC's and i really like what I am hearing. More forward sounding than the previous version.

Side tracking a bit, I made a quick DIY digital cable cause I needed a quick fix till I find out if I can go I2s or not, and was using a borrowed digital cable (If I can't go I2s was thinking about a Lenehan dig cable). The one I was using was very good, to me anyways, really made an impact on my system (don't think for a minute I'm anywhere near the level you guys are at). So I got 3 strands 0.25 solid core, 1.5meters long, braided it (got mom to help 8)), 2 strands positive, 1 negative, cheap jaycar plugs, no solder. Sounded decent straight out :o

15 hours burn-in this thing started to really sing, was up till 5am on the second day when it started breaking in, and still continues to improve daily :o What can I say I'm blown away I was expecting pretty much NOTHING to come from this. Haven't made direct comparisons yet, but my money is going on the DIY to better the one I was borrowing. Surely this DIY cable is not true 75ohm.
