In hindsight, perhaps the choice of the term ’color’ was a wrong one to start with. The term might imply some sort of artificial sweetness or making the sound unnatural. That was not what I was aiming for. I started to write my response but then I read @hilde45 ’s last message. He pretty much summed up my thoughts, albeit, in a vastly eloquent manner :) I wholeheartedly agree with everything he said.
My intent was to discuss how to shape the sound signature to something you enjoy but without taking away from the intrinsic nature of the original recording. This does not imply bad synergy or other weaknesses in the chain. I’m sure this is not a novel idea. There’s a reason many audiophiles combine SS amps with tube preamps. or use a hybrid amp, and are happy with the results. Obviously there is more than one way to skin the cat. I never understood why some audiophiles are so dogmatic (my way is the only right way) about these things. Relax, it’s a hobby that’s supposed to make you happy -- whichever path you choose to take.
Early on in my audio journey, I too was enamored by tweaking the sound by introducing a tube dac in the chain. I tried a couple of tube dacs but overtime I concluded that it was not always the best strategy, at least for me. Nowadays, I prefer my DAC to pass on the information as accurately as possible without altering the signal. But that’s just my preference. I’m sure there are many on this forum who are digging the sound of a tube dac as we speak. That being said, I never tried higher end tube dacs from, say, Lampizator’s upper models. I might try this route in the future.
For now, I’m thinking of trying a tube preamp with my SS amp. I want to point out that I’m perfectly happy, in fact more than happy, with how my system sounds right now. It has all the tonality, texture, presence, etc. that I had always desired. So the urge to try a tube preamp is purely an experiment in the realm of ’what-if’. Just to push the envelope a bit more. It might not work out in the end. I guess there’s only one way to find out.
