What the benifit of using a separate dac?


Hi, I have a Sim Audio Moon Exclipse Cd Player, my question is what's the benifit of using a separate DAC, when do you know that your player is out dated to the point that you need to upgrade or are you better to use a external dac.Using the digital out put of the cd player are you by passing all internal clock and dac's etc, then the player becomes just a transport? Is there is a benifit to be gained by doing this, what sort of dac would you look for, what the differance between the better brands? I currently have Pass labs X1 pre and x350.5 power, mit 3.1 speaker cables, 2.2 interconnects and Talon firebird speaker, Iam only interested in red book, would be great if any body could shed some light on this subject for me.

I purchased a Sony ES player back in the 80's....done good player. But I got back into Hi End about a year ago. I felt that there had to be improvements made...so I wanted to keep my Sony 707 as a transport...A stand alone DAC was next on the list. Tubes or SS...well I read everything I could on the net...my Budget being about 1200....I chose a Monarchy dac....hooked it up....very good. I changed out the stock tubes for NOS Amperex...now that was a significant upgrade. The best was yet to come....swithed out the coupling caps....that did the trick. I'm done...as this dac now produces silky smooth,dynamic and crystal clear sound...all for 1500 not bad.

I can and do appreciate your exp and no doubt the modding path has been a beneficial one for yourself and I’m glad for you.

You and I aren't too different… nor for that matter are most of those who frequent the high end audio market. Very little of the abundance of gear is available for local preview. some of which that is available, I’ll just not go thear due to the way that dealership treats people routinely… and I’ve tried more than a couple times to do business with them in spite of their erudite and arrogant attitudes.

90% + of my rig has been purchased sight unseen/unheard. Nearly all were leaps of faith. Yet nearly all of these leaps of faith were fortified with plenty of press and other current & previous owners recommendations. In spite of some actually.

I do my due dilligence… as it is to me to do… and that’s exactly my point as you agreed by saying some of the modders will ‘sometimes’ show off their mods at some of the shows. I’d guess these show pieces are their full on mods as well.

Exactly. Some, sometimes, somewhere. Maybe.

Specific alterations for improvement aren’t for the greater part responsibly accounted for too often. Nor are those accounts ongoing in the more common areas one would look to for such reports… only short raves are posted from those who have subscribed to and paid for them.

As such, these reporters have a vested interest and can’t be considered objective descriptions IMHO.

Well, not 100% anyways. Neither do I discount them wholely.

On the other side of that coin of vaunted increase, is the reliability and contact issue. I tried a couple years ago to contact some of these after market aficinadoes and from some was not even given so much as a simple reply email. Only Steve of Imperical, Mr. Jesse out of Michigan and Richard Kern have spoken to me on some CDP improvements. One was far beyond my ability and the others were left unrealized given the results of the conversations.

A couple others I got to that have a reputation for upgrading components struck me as quite biased and arrogant outright talking down dissmissively of various manufacturers designs relative to their own efforts. Consequently I gave them no further thought.

People are people I suppose and I guess one can’t expect everyone to be polite and objective. I believe one can expect contact and communication to be part and parcel aspects of doing business with them however… and in my exp, this last facet has shown itself to be less than satisfactory. I’ll also add I’ve had even less satisfaction with standard ongoing prominent makers of high end gear too. Quite possibly this vein is simply put, what one has to deal with in upscale audio concerns… and that is indeed a shame.

Nevertheless, I understand the constraints of gear makers which follow a more wide spread concern dissallowing a no holds barred effort… and the after market adjusters which affford the end user an opportunity for greater gain.

Fine. Good.

I would merely prefer to see more objective accounts, such as those written on R. Kerns and D Wrights and others’ efforts. There are quite a few online outlets for such info too for this to not be done.

I see no reason to keep any viable measured performance enhancements as more the ‘well kept secrets’ variety, rather than the openly reported.

Hope you can see the sense in my opinion here… hopefully more modders do too. I’d dearly love to hear objective accounts from any of these hot rodders less than full on mod results in the same online publications we all enjoy and use routinely for help in making our buying decisions. Of course there are those rags which will not publish such matters yet there are those which would.

Naturally as I mentioned also having units on hand which possess such alterations for home trials would surely gain for them far greater appeal.

Shedding such a brighter light on things would benefit both modder and moddee.

I mean given the choice in our leaps of faith, would not all of us prefer to just jump a school bus or two, rather than the Grand Canyon?

We ain’t all Evil Knevils, ya know.

…and isn’t “BETTER” a pretty vague word after all.
Blindjim,

Interesting thoughts. Perhaps modding is partly based on a desire to differentiate - to have something better than or at least different from the next guy. To enhance the feeling of ownership pride by an extra level of customization. Audible benefits may be quite small but kudos is high in the mind of the owner. This is where the value comes - like the guy with the Honda all kitted out with various customized items - he wants his Honda to stand out from the other Honda's - it isn't only about improving the performance.

Hmmm. I never even considered that part.

Your analogy is eirily on target for me though. I had several scooters and had two of them modified, one Honda and one Kawasaki. Both were done through primier after market companies that had gained their reps by virtue of consistent results at the race track. Both Yoshimura Racing and Russ Collins Engineering, (respectively) recieved a lot of press not only on their build alterations, but from actual trials from the two wheel mags.

These full on or partial refits, or even their kits for the DIY'ers, were not inexpensive. Neither were the results subjective. The ride and the feel indicated the improvement, but it was the clock that truly told the story in that arena.

cosmetic changes too were made but mostly they were an afterthought and not the main thrust. I've always been more about the dash than the splash.

Value of the end product was seldom ever a consideration then. It was strickly all about performance and reliability. Getting there first without blowing up.

I got there first a lot... and yeah... I blew up too... once or twice. The explosions though were my bad not the modders.

Mo press is needed. As subjective as it may wind up being spent, if it could gain some modicom of objectivity via folks who do not have some vested interest would go a long way to further fill the voids in the minds of the prospective buyers, and the pockets of the professionals doing the alterations. IMHO
Blindjim - I don't get the connection to motorcycle performance mods aimed at boosting torque and HP for faster lap times. Those are mods easily measured by a mechanical (objective) device. Humans are not objective. Music is emotional. You can chart brainwaves, pulse rate, skin temp, finger movements, etc. But what all that actually translates to an individual cannot be quantified or experienced by anyone else. If you wanted to find a parallel in motorcyle performance mods, I would say it is more akin to mods to suspension, chassis, rubber, frame geometry - those things that are specifically tailored to an individuals preferences and riding style. If you ride you know that dyno charts do not tell you the whole story about how a bike will take you around a course. Even with the closer metaphor I would still say that the reproduction of music in your home is an emotionally charged experience and cannot be quantified by charts and numbers.
