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.

My point from the onset is or was to illuminate further the curious lack of objective press reviews on the outcomes of after market mods of audio gear.

To that end, both courses of action before the facts were for proposed advantages or increases to performance. One being a scooter, the latter our audio apparatus.

The bike upgrades had better representation via the industry press. The theme here is tantamount to the same province, "imcreasing performance or improvements" via the same sort of after market enhancements... albeit without the same publicized notoriety.

I subscribed to, bought, and utilized those speculative hot rod modifications costing me thousands then due primarily to the coverage the industry press printed about them, by and large.

My last statement pointed to just that item… mo’ press from non invested reviews would lessen the leap of faith required to pursue these measures.

Sorry if it wasn’t clearer.

I’m not haranguing audio modifiers here but merely pointing out a viably solid path to quell reticence, or eliminate it altogether from the minds of those seriously interested in attaining said levels of augmentation

As for myself, I’m thinking to ask for a couple grand or more with but a subjective promise up front could well be fortified still further by such credible monologues ….

Truth be told, I find it curious such accounts aren’t ongoing and at least the now and then sorts.
Blindjim - just to toss monkey wrench: Empirical Audio converts upsampling jitter rejecting DAC (Benchmark DAC1) to NOS non-jitter rejecting DAC (plus other improvements) -you might be sorry with cheap transport and cable. I'm pretty sure Steve from Empirical Audio advices customers but others might not. The point is that modds sometimes can change functionality/make it worse and customer has to be informed.

I even suspect that some mods might introduce a little of harmonic distortions that Benchmark is free of to make sound more lively and less sterile (less clean).

My modding plans surround my Bel Canto DAC3 initially, and following that operation, perhaps an Oppo refference DVD player I believe I'm going to get as I'm going to go largely with the PC as a source now.

But that's an interesting point too, as each time I
've replaced an item with some likewise yet different thing, there has always been the need to re-address some of the cabling... or footers... or tubes.

it's seldom been a plug and play event. I suspect once a thing is 'changed' it would be the same deal again.

BTW it was because of the press and my limited talks with the Benchmark makers that sent me away from previewing that piece altogether.
...curious lack of objective press reviews...

That is an oxymoron. Where have yous seen "objective" press reviews on anything? How could there be such a thing, a review being written by a human being is bound to be subjective simply by definition.

Your clarification on your hot rod metaphor still doesn't connect with me. You're talking about mods that can be measured on a dyno (which really don't tell the whole story about how they translate real-world anyway - 90 ft lbs of torque may not be a good thing if the suspension and chassis isn't up to it, or if you don't know how to handle it). Also, there is an emotional disconnect with those mods, or rather it's not the same kinds of emotions involved in the enjoyment of music and the reproduction thereof. Bottom line is that the numbers do not tell the whole story and "objective" is only a tiny part of the picture. In my case I tend to largely ignore such things beyond the general knowledge of the component in question. What would an "objective" review of a modification read like?

Blindjim,

Interesting comment based on our discussion about one of the primary drivers for purchase decisions is the desire for differentiated products. The comment says more about you than the sound quality of Benchmark DAC1.

Is it possible that you chose not to preview it because of all the near universal accolades in the press and from professionals combined with relatively modest price means that this is an EBGO product in audiophile terms. EBGO = Everybody's Got One! Therefore the attractiveness of owning such a product is rather limited if you have any inkling to own a differentiated (more expensive) or "better" product.

If you mod your Bel Canto then you can feel even more secure that very few people have what you have!

FWIW: My friend and I bought two identical scooters when I was 15. Same store. Same model - probably produced within minutes of eachother at the factory from the same batch of parts. We had a 30 minute run to school each day and followed eachother. The performance was as near identical as you can get. At one time we got interested in modding to try and eek out more speed from these 50 cc slow-peds. instead of buying two racing type mufflers (with the motorcycle dealer assurance of a significant speed boost) we bought one and tested it. Well is sure sounded different - his scooter had a deep satisfying Harley imitation sound (nothing like that patented Harley sound mind you) while mine remained with its standard millions of scooters on the road sound. Now here is the kicker - my friend took it back a week later and got a refund because it did not make one IOTA of difference to the speed or acceleration.

To end the story, although I have lost track of this old friend, he also became an engineer. It may have been a formative experience. Engineers tend to trust higher authority. Engineers tend to believe text books. Engineers distrust anecdotal evidence without controlled testing and documented measurements to back it up. For Benchmark to plaster their measurements all over a manual with each of their products sold is a very bold thing to do (as any engineer or anyone with manufacturing experience knows). By offering so much detail and information one is exposing oneself to a potential huge embarassement (if anyon eproves you are full of it) and expensive product recall due to lack of performance/conformance should your products not live up to the published specifications (one year to the next). This is very unusual in audio.
