Is no preamp the best preamp of all?

As an experiment I hooked up my OPPO BDP-95 (which has a volume control) directly to my amp. I was very pleasantly surprised to hear a significant improvement in clarity and sound quality. Typically I have the analog outputs on the OPPO running through my preamp in Analog Direct. I have heard that the circuitry within preamps can cause cross-talk in the analog signal, deteriorating the quality of the signal. So, would having no preamp (and therefore no other circuits to interfere with the signal) be better than an expensive analog or digital preamp running in Analog Direct? I am not really interested in Room Correction or DSP of any kind. I was considering purchasing a Bel Canto PRe6 (which I've read is excellent for multichannel analog), but would it be better to just have the OPPO running directly to the power amp?

Yes, the Lightspeed works without anything in the signal path!

I have an oppo bdp 95 too, but my grant fidelity cd 427 tube cdp player is my reference. I actually tried not using a preamp as far back as the 80's with a yamaha M 80 and it sounded flat. I guess on some equipment it works better simply because of the design. I agree with some of the comments, there is NO one solution to every setup, it's all a matter of taste and preference. If there was such a thing, it would be safe to say that everyone in this hobby would be buying exactly the same products and manufacturer if they had the funds.

I liked the response that said there is no such thing as no preamp.

It sounds like one must experiment to see if a preamp improves one's sound in one's system.

Removing the cables and circuitry when not needed should help, it seems.

I've been going from a Theta cd/dvd player to 300b amps with individual volume controls. Sounds great, but what am I missing?

I do need a preamp with phono and microphones, that's clear.

It seems like convenience is another reason to have a preamp -- selecting sources, remote volume in some cases.

But I probably don't need another preamp if the output from the cd player is enough and I have volume controls in my amps.

But I am tempted to try a tube preamp and remove the volume controls on my amps.

Your thoughts?

If you have volume controls in your amps you stand a good chance of making it work. When you have a stand-alone volume control with cables feeding it and it driving a cable, the math tends to go against you and you will loose bass and dynamics as a result.

So in this case, there could possibly be "no" pre-amp? I have a pair of SAR LABS "Little Walleys" monos with level controls. I tried this experiment with a player without controls to great success. Much better without the pre.
