Re: Preamps with DSs
Hi Folks, Regarding what happens if you "throw away bits" without dithering or filtering: If anyone would like a visual representation of some of the issues being discussed, here are a couple of MATLAB outputs (just randomly grabbed from the first page of hits when I Googled "Fourier Truncation").

Yet Another Praise of Source First =)
Hello Everyone! If you'll forgive my preaching to the choir: over the years I've read many posts extolling "Source First" -- but although I've consciously accepted this tenet, until this week I've never had a visceral, oh-my-goodness, personal experience to really drive it home. But now that that's ...

Unidisk's back!
Hello Everyone! The Unidisk SC has come back from warranty repairs, and is playing happily as I type. And for the possible reference of any other US-based Linn fans who might someday wind up in a similar situation, here's how everything worked out: 1) My poor little UniSC wound up needing a fair bit...

Unidisk SC Transports and Linn's 5 Year Warranty, in USA
Hello Everyone! Ostensibly this is a question that should go to the official Linn forums, but since I trust everyone here much more, I hope you'll forgive my asking on this forum. =) Here's the issue and question: The Issue: My father's Unidisk SC (purchased new just under 5 years ago here in the US...

Stability with age and environment? (And congrats, too!)
....I settled for the current circuit a year ago. Back then it was a tiny amp that could be housed in a Kikkin enclosure and the name of the project was 'Fling'.... I could have released Fling in spring 2011, but I ran into a problem. Variations in quality turned out to be big. In other words: The ...

Re: In Praise of the Pre-amp (Kinos with Unidisk SC)
But as the playback system is VERY good, any upgrade in the source/pre going to make big increase in performance. Been there done that :mrgreen: Yes, I look forward to being "been there done that" with a better source someday! :D Before the DS units began coming out, Source improvements beyond the ...

Re: In Praise of the Pre-amp (Kinos with Unidisk SC)
Mr. Lejonklou, thank you for the comments & reply -- I owe you a response, but for now let me quickly address Music Lover's post: And finally, why did Linn pair a nice source (the Unidisk SC's disc section) with a preamp that (apparently) limits the overall system performance? Is it a matter of cost...

Espek Position and Tune Dem
Hello Pete, Agreed: "swaying in the breeze" doesn't sound too optimal! :D Is it because the spikes aren't penetrating through the carpet?

Anticipated Performance?
Mr. Lejonklou, I don't really want to put you in an awkward position :D, but if you wouldn't mind making a performance prediction, where do you expect the Kikkin to fall performance-wise among the existing Linn preamps (in simple 2-channel stereo mode, of course)? That is, do you have a sense as to ...

It's not about "partially-cleaned" - it's about doing it correct!

This could be true in some cases, perhaps including the Keel. But in general I think it's incorrect.

Thank you, Mr. Lejonklou! Sounds like mass without gross damping is the goal; I appreciate the info on the solid vs. inverted-U bases. (Also, just to let you know: there's an option beyond steel or lead shot that I'm not pursuing -- fine garnet grains are also readily available (and they're even les...

Hi Ceilidh, Wow - that's certainly a good attempt at explaining the science behind source first. I don't think I'll comment on the detail if that's OK as its a bit over my head.

Thanks SaltyDog, :D Agreed that lead shot would offer considerably more damping (and it would also be cheaper, and easier to attain high weights and densities). My concern is threefold: 1) Somewhere in the maddeningly user-unfriendly Topica forum, there are posts made years ago by (I think) Mr. Lejo...
