Best path to upgrade my source


I am a new start up in the stereo world. At present I have an Audible Illusions pre, 200 watt tube mono's, dynaudio 1.3 mk 11'S, and a highly modded marantz cd67se. I would like to upgrade the front end source. I am on a tight budget, and I'm considering either a Benchmark dac1 or Naim cdi or meridian 506. I prefer acoustic, soft jazz, and mild rock and roll. My listening habits revolve around detail and immediacy as my 53 year old ears have heard better. Any suggestions?

I'm happy with my Lavry DA10. As it has perhaps the most sophisticated reclocking, any old transport will do.
Anthony,

Aside from the general proposition that ANY component may benefit from a better power supply, do you have any information suggesting that the power supply of the Lavry DA-10 is inadequate? How does the Lavry "suffer"? Have you auditioned one? If you have any real information or experience please share it with us.
Anthony,

I've looked inside and don't find anything there that is surprising. There is nothing I can hear on a pretty revealing system that indicates an EMI problem. It is extremely quiet. (Specif. at -109db minimum not weighted)

I can't believe you have any experience with this DAC. If you want to prove me wrong why don't you share your advice with everyone, not just me privately. Let us know how you can improve this DAC. Perhaps then I can forward it on to Dan Lavry for his comments.
"You mentioned "Any old transport will do?"
It would depend on the answer of; "Does the music really matters?"

Anthony,

Almost any transport can deliver the bits. With error correction it doesn't even have to be 100% accurate.

A good reclocking circuit in the DAC liberates us from expensive players and cables. That's the main point that a lot of manufacturers and their allies among reviewers don't want you to know.

It's not only theoretically correct. My ears tells me it works.
Anthony,

You're way off base. I have changed, improved and altered enough power supplies in my time to recognize when there's a problem that needs it to be made better. You may or may not believe it, but the Lavry DA-10 doesn't need help in that respect.

I don't have to forward your views to Dan Lavry for he has already addressed the issue of a switching v. linear PS in writing. His contentions are that:

1. The generic audiophile critic, by which he must mean someone like yourself, probably has not kept up with the improvements in switching technology. That in the DA-10 is more expensive and better for the application than a linear. Switching PS are harder to design and many "audiophile" designers are simply not up to it.

2. A "linear" PS is only partly linear anyway as only the regulator is "linear". A diode bridge or a center tap 2 diode rectifier is not. The current through the filter caps and/or inductor switches.

3. Linears generate heat that adversly affects reliability and performance of components. Switchers do not. Linears also generate 120 Hz noise (within the audible range). A switching PS generates noise above the audible range, and keeping that noise above audibility is accomplished with good design.

Lavry designed the original DAC module for Mark Levinson, Wadia and Pacific Microsonics. His DA924 is used by many of the top mastering facilities. He is exceptionally well published, on the internet and elsewhere. I did my homework before making the purchase. A unit doesn't measure noise at -110db unweighted if its switching PS is not extremely well designed.

Perhaps you can tell us what you have designed and published.

If your understanding of error correction and a reclocking circuits are as wanting as your understanding of modern power supplies I rest my case.

PS: Ncwogger, save your money. Having Anthony replace the PS in the manner he describes will in all likelihood degrade Lavry performance.
