Best preamp is no preamp: always true?

Newerphile, My opinion, lost dynamics and frequency extremes, could sound flat and yes make it seem more like a digital boring source. maybe not every case but in most, basically look at it this way a preamp is sorta line level amplification like an EQ would be, it will boost some of the frequencys to a fuller sounding range not because that is really its intention but because no matter what you are playing with the tiny voltage signal coming from the cd and any extra gain added to a signal that small well will sound like 10 times more effective than going from like a 50 watt amplifier to a 350 watt amplifier if that makes sense, is it pure?, is it Zero distortion?, nothing is, but the closest it sounds like emotion in the music the better in the end, this is mostly achieved by using a preamp in the chain than not from my experiance.

I've tried it in the past and it's not bad. But the preamp/buffer stage makes it a whole lot better IMHO. It never sounded slow or fat. Just slightly hard on cymbals and such. It's like having too much of a good thing that wears on you over time.

If CD playback is your only source then you'll just need to get an expensive CD player with high output + volume control. In this case, the "less" component is better off.
This is different from having a passive preamp. I would go with that than having a passive preamp in between the sounce and amp.
The ONLY drawback is CD player choice. You will be limited to less than a dozen of expensive players to choose from.

As far as DAC goes, it is same idea as CD player with volume control. In this case, you'll be limited with DAC that has high output plus build-in volume control.

We have the same fancy (or as they say in the car industry, "pants") CD player as TVAD, and also find that we prefer having the preamp in the chain. It allows for better separation of the instruments, a preferable 'gain floor' as a complimentary support to the amps, and it conveys a more meaningful heft and density to the music. If we run direct--and our player does have an outstanding hybrid attenuator--the soundstage collapses, and on anything other than light chamber music, vocals or soft jazz, I'm just not feeling it. We take the preamp out, and it sounds like the music is struggling to get out, losing a sense of ease and realism in the process.

Some people will choose a configuration according to sonic preferences, while others wouldn't think of adding the preamp in the interest of maintaining a purist's approach. As TVAD suggests, you'll have to decide for yourself.
