preamp vs. no-preamp

Hi guys, I would like to know your opinions regarding the classic question (which also has been posted many times in this forum, I know, I know) whether or not a preamp is needed for a good (= musical sound). You see, if you can delete the preamp and connect the DAC into the poweramp, you can save lots of money, sometimes up to $ 15,000 for a Conrad-Johnson ART (this is off course an extreme example). The money you have spent on the preamp can be used for buying a better source or amplifier (mono's?). So theoretically if you don't have a preamplifier you can improve the sound reproduction by: deleting redundant audio circuitry and interconnect cables, upgrading the quality of you source, poweramplifier or speakers.
My personal experience is that without a preamplifier the sound is becoming thin and uninvolving, but I know there are audiophiles who don't have a preamp in their audio system.

Adsal,congratulation you have the BEST DAC in the world.
What did you have before? M100?

How close the sound compare to the analog ?

Sell your Tenor and buy the Ongaku Fuji !

Good Luck and love to hear your system.

Anyone knows if there is a DIY guide or circuitry for transformer based passive preamp?

I stay with my preamplifier! Poor Dazzdax, I wonder if he is going to count the results of this discussion and then go with the majority...As Tok20000 and Czbbcl I had the same experiences. Connecting my Accuphase directly to my Pass results in a flat non musical sound. Going through my ARC Ref1 preamplifier made the whole difference. I did the same test with a Wadia 861 and an ARC VTM200 and then through an ARC Ref2 preamplifier, same result. Finally, Wadia 861 to Nagra monoblocks directly, then going through the Nagra PL-P preamplifier...same result. In any case, I do not mind to keep testing, after all is part of this vicious hobby. But in my experience has allways been consistent. Going through a good preamp is the best way.

Marakanetz, there is good info at this link

www.bentaudio.com

They have parts, kits, and info on building these passive transformer volume controls.

They also have complete units, with either manual or remote controls.

Gecus- Your experiences are interesting, I would have to agree with the CD players you used. I had an Accuphase DC-300 digital pre and I never cared for the volume control on it- it like the players you tried use a digital volume control, which some claim drops bits. I did not experience bit dropping per se how ever it just never sounded smooth enough it always had that digital edge/glare to it.

Sutts- Thank you for reinforcing me trying that PC, I will have to give them a shot! Hey you never know until you get it into your system.

This is really very helpful, I never realized we were all this split in our opinions on the subject :) I nice friendly disagreement- Happy listening everyone even if you use a pre ;)
