Preamps can color sound considerably. Surprising?

Had the pleasure of listening to 4 hi end preamplifiers this weekend. And each preamp sounded very nice. But they were different. Each preamplifier has different circuitry and within the frequency spectrum there was more vibrancy in some areas versus other areas. Amplifiers are the same way.

It takes a while to appreciate sound differences between preamplifiers. And then you got the issue of Breakin which further changes the color.

clearly designers are playing around with all the internal circuitry in a manner that hopefully will be appealing. Clearly, these units do not get out of the way when it comes to moving a signal through the box.

I think solid state is more susceptible to coloring versus tubes. Tubes color sound as well.

It's all about marketing different ways to color Music. This isn't necessarily bad but it's never really talked about this way.

In general, I hate use of these long-stretch analogies with audio. They mainly serve to further derail a discussion that was already careening off track. Don't have relevant experience to the topic at hand? No problem! Anyone can make up a wild analogy!

Anyways, I'm surprised that team passive preamps hasn't compared the active preamp to an appendix 😅

Personally, I‘m rather in awe of the “Gallbladder machines“ one sees for sale from certain Chinese audio merchants….

It‘s funny how people argue about this subject. Attenuation and amplification are fundamentally different and the simple fact of the matter is that dacs only require the former. So what may be useful in amplifying a phono signal with rare exemptions become distorition when a dac is used.

@condosound.. 

"scm: Thanks re Tortuga LDR, I’ll try to listen to it sometime. But it needs external power, and so it is not truly passive. I have a 12 VDC battery-powered Dodd Audio preamp which is not passive, but it’s absolutely silent. Can you switch the Tortuga to battery power?"

.I have mine hooked up with a battery supply and it made for a much ’blacker’ back ground.

But one can also just use an amp as a buffer to change impedance.
If the DAC does the volume, and not other things need to be switched, then one does not need the attenuation nor the amp.

 

One of the rare exceptions is to drive the cables better to the amps, should the output be driven to very low listening levels. If the OP is not using horns and a high gain amplifier, and not listening at a low level, then they have less to consider.

But which arguments were you referring to?
