DAC to Amps bypassing preamp: Opinions please

A preamp has always sounded better in my system. This is playing with any top CD player with great analog volumes including a Opus 21, AA Capitole, Muse Thalia and Quad unit. Each and every time without fail a preamp was needed to get more dynamics, full and weightly sound and tighter bass. A ood pre is a must based on my experience and much if it :-)

Sure it will sound good without, but when you get around to putting in a good pre you will wonder why you waited so long.

the only plus going direct is the money savings that could go elsewhere in your system. A good pre that fits your taste is allways going to be more fun to listen to than a passive-allways(keeping the rest of the system the same). its the tradeoff of having something else in your system that is going to be better and the feelings of knowing that in your brain- ie. 7 thousand dollar better speakers for example that you will need to decide which you want more. to do a fair comparison you must keep the total dollar vallue of your system the same. Otherwise price becomes a deciding issue which is why so many people think they prefer passive in the first place. They drop a passive into their system and change nothing else- boy that sounds great! But any comparison that changes the total cost of your system is not a fair comparison at all.

Thanks for the responses. What I'm not sure I understand, is since a DAC outputs an analog signal, isn't there already a certain amount of 'pre-amplification' being done already at that point? If this is the case, why don't more manufacturers provide just a bit higher level of amplification with a volume control that is meant to drive amps directly? I now only have digital sources, where everything goes through the DAC, so having an extra preamp seems like a waste. It this digital age, that would seem like the way to go.

I disagree. Going direct, assuming the DAC's attenuation is done well, will give you clarity, purity, and image stability (among other things) that you will almost surely sacrifice some of when you add another component and set of interconnects. That's been my experience. Again, you may prefer the sound with the preamp. It's usually more dynamic, has more "body", and produces a larger soundstage. But it's not all upside IMO.

Smeyers, you are asking the question a thinking man asks, which is why should this be so. Other than impedence matching, which is usually not an issue, no one seems able to give a satisfactory answer. Which makes you wonder... It's a fertile topic for cognitive dissonance, that much is clear.

For the record, I've bounced back and forth for more than 10 years between going direct and using a pre.

Conrad-Johnson is introducing a $6500 "control amplifier", which is an integrated without a traditional preamp section. No doubt some people will use this thing with a separate preamp.

Probably above your price range, but George Mark Audio has a DAC/linestage which includes a true preamp linestage as well as the DAC processor. You could bypass the linestage if you like, although I don't know why you would do that if you're goint to drop $6k on the unit. It is a tube unit as well. This approach I believe is better than the DACs that just have a volume control. It is more expensive and you're not really eliminating the preamp from the equation, but it is also more compact and for those who have a one source system could work fine.

Mahandave - I'm in the middle of figuring out the passive and active dilemma. I have a Joule Electra LA-100 MkIII and love it. It is not mating well with my amp (too much gain overall). I'm using EVS Nude attenuators right now between the amp and preamp to drop the gain so I can get some flexibility on the preamp volume control. I have had a couple of passives in for audition and did not like them, but I do like these EVS attenuators which I tried with my DAC as well. I'll be getting a TVC this week custom built for me by K&K Audio using S&B transformers. This will be the final test.
