Sonos + Cullens Mod

OK, you'll have to explain that to me.
Jitter can't really be undone to my understanding as it is an error in the incoming clock. If you re-clock you are just applying a different clock, you have no idea how that relates to the original clock. And could you explain the FIFO comment?
I thought I understood all this until the Naim White Paper (on their DAC), which was clearly no more that marketing smoke and mirrors as their DAC clearly doesn't correct Jitter, it just doesn't make it worse...

The Naim employs a RingDac. The Meridians use different techniques, using dual locked PLL circuits. The FIFO buffer effectively re-assembles all the input data, a clocks it out with a local clock (in Meridian's case a stable one!)
Have a look at the Meridian 518 manual (be careful there are many ways that you can use the unit). De-jittering is covered in Appendix 4. I've had one (actually two at different times!)and with older DACs found that it made a big improvement, but with a later Meridian DAC/rocessor, it made no audible difference so I sold it.

There is one for sale on PFM, they hold their value so you could buy it, try it and oif you don't like it sell it on without losing any money.

Spoke to the guy who does the Cullens mod in the US. He also does a DAC which he claims is able to undo Jitter. I'll leave it to you guys to decide. I had a long convo with him and he knows his Onions.

Lots of people in any industry make claims, but I prefer to buy hifi from respected companies where the equipment has a decent resale value if I decide to move it on or upgrade. I don't think that any DAC can eliminate jitter and often the audible effects of jitter are over emphasised.
Buy something on it's sound quality not on it's technical merits!

Totally agree. They offer home demo, so no risk. I just like to understand what I am buying. Naim, falsely project the myth that their DAC was immune to Jitter. I read the white paper, time and time again. Couldn't get my head round it. Then low and behold, it was all b

I have a hearing defect from birth, so it takes me a long time to appreciate music, as I have to "listen for it". Home demos, which last less than a month don't offer that much to me. Therefore I try to select stuff based on as much scientific fact as possible. That way, in a month, there is at least a small chance I'll like what I am listening too...

And Audiocom are expesnive as well.... Plenty of people who will fit Trichord clocks etc at a fraction of the price. The biggest issue with modding kit (just like with cars) is that you'll never see your money back at resale time. Is it better to just buy something decent in the first place?

Well had the WFS DAC for a week. Bloody hell it is good. Blows the Naim out the water. Thats DAC for DAC, no doubt a Naim PS would take the Naim to another level.
The WFS DAC is technically almost identical to the Weiss DAC and was recently reviewed against it, where it only just lost out. I suspect that was more to do with maintaining the Weiss hospitality.
What ever, at £1300 it is a real bargain.
Off on hols but when I get back I have a home demo of the new Antelope DAC, which is meant to be a step up from the Weiss.
