Preamps waste of money?


I've been forced to reevaluate the role of preamps. The best sound I have achieved is result of adding a stepped resistor volume control at the input stage inside of my tube amp. All other options I have tried or auditioned including both active and passive volume control(autoformer and LDRs)have "colored" the sound in one way or the other to an unacceptable degree compared the stepped attenuator at the input. Has anyone had similar experience?

Ralph, I have two digital sources and don't mind switching interconnects between the two, which I only do once in couple of months. Getting up from the chair to change volume and balance can be PITA, but I've gotten use to it. However, I have a solution...I'm getting remote controlled stepper motor for my Goldpoint attenuator that can adjust volume and balance. Two stepper motors, two Goldpoint mono attenuators, and control logic board including the hand held remote cost me about $500. Obviously you have install them yourself or pay someone to do it for you. I can't conceive of getting equal performance, unless I'm prepared to dish out serious money for a remote controlled preamp (ie, $15k+). It's mind boggling to me when I consider the amount of money I would have to spend on an external preamp to equal this simple setup in my system.
Last_lemming, I think your assumption less is more going the passive route is essentially correct, as long as you have equipment that are compatible and willing to make some sacrifices. I think I got lucky going this route.
The lack of odd order distortion is probably why many listeners find tube preamps more natural and realistic without likely knowing exactly why.Even order harmonics are consonant with music(overtones and funtamental) and nature.The thin and dry sound of 'some' SS components could just be the product of odd order disortion(no matter how small its presence?).
Brighter sound of SS amps is related to Transient Intermodulation distortion (TIM) caused by negative feedback used to linearize output transistors especially in class AB amplifiers. Product of TIM is overshoot of transitions (in time domain) equivalent of producing odd order harmonics (in frequency domain). On the other hand overly warm gear, that might sound great on guitar or voice, can make other instruments with complex harmonic structure sound wrong. For instance piano, that has harmonics much more complex than simple overtones, can sound almost "out of tune". Ideal amp shouldn't add anything of its own, IMHO, pleasant or not.
Kijanki, I used to own the Hyperion 938s, one of my favorites. I think I was the first to own a pair in the US having purchased them in 2004. I miss them, but to big for me. I would buy them again if my back wasn't so messed up. I have to say the 938s sound great with tubes and smooth SS.

I prefer an amp which is just a touch on the warm side of neutral. On 1 to 10 scale, 1 being sterile and bright, 5 being neutral, and 10 being overly warm/ripe, I prefer 6. Just because more recordings error on the lean side.
