Aren’t there five wires Si?

Even at full listening volume matched to the level I listen to my dac at there's no audible noise with an ear to the speakers. The first thing you hear is transistor roar and that only becomes audible with ear at speakers and the volume dial on my pre twice as far round as my usual listening level.

You boys must have some noisy tt's/wires.
I think a lot depends on the system and listening environment to be fair Simon. Whilst I couldn't actually hear much difference (there was a little in terms of loss of very fine HF low level detail as we replayed a track multiple times when conducting listening tests), the main difference were highlighted on the scope.

There was clearly a lot more "hash" on the signal when using unshielded plugs. Whilst this didn't result in a highly audible change didn't mean that good practice in shielding everything on the low level signal path wasn't worthwhile, as it was easy to do. I guess that just follows my approach generally which is if it can be done and makes a measurable difference then that's what I usually would choose to do. Attention to detail I do think matters at least when designing something to be as good as it can be.

Sometimes this might make no audible difference but I know at least everything is as good as I can get it. I'm a little fussy on details which is a disease unique to engineers! :lol: Where it doesn't matter as much, granted, is at line-level. That's just my personal approach to these things though and I appreciate that others may justifiably not be as bothered about these things.

You've clearly gone the extra mile with the Paradise, which by all accounts is an excellent phonostage. Hopefully I'll get to hear Chris's at some point this summer, something I'm looking forward to.

I'll be doing some work to chriss's at some point, not sure when. I have a new build slated as soon as I finish all the kite cad.

Mark, no there's just the four at that point, the fifth that earth's the arm connects at the exit point on the back of the arm via metal to metal connection to the headshell. There's no fifth wire in the arm tube.

Welcome any time Paul.

Glad you recall Simon, am hankering after getting it done when convenient to you, once travel restrictions are lifted in the not to distant. Thought was to perhaps drop it off on the way through to a work visit, then swing back around and stay local for a day on the way back a few days later, at the weekend perhaps?

I'll dig out the box of bits I have, z foils and the gold leg things. Not noticed any other developments but would be happy to throw the kitchen sink at it :-)

Humph :(, I’ve hit a bit of a stumbling block. I had thought that I could get all the bits 3D printed from plastic to check a bunch of geometry, force and aesthetic stuff out but...... I uploaded the files to a company yesterday and their quote was double what I had hoped for :( - pretty blooming expensive in other words. I’m not quite sure what to do now - bum! My problem is that I’ve previously done so much of the prototyping and build of projects myself I’m out of touch with how much companies charge for doing it for you!

Prices everywhere have gone up Mark. Only two years ago I was able to get specialist CNC machining services for £27/hr. That same company now charges £42/hr plus of course materials.

That's why I've enlarged the workshop and invested in more tooling and machinery, to do all that sort of thing myself now.

We've been forced to increase prices twice so far this year due to raw materials. Texan weather, fires at refineries, slow down at ports due to covid and a litany of other reasons.
