Tube rolling is SUPPOSED to be about finding the 'best' combination of tubes to highlight the strengths of a given amp - not endlessly changing tubes to suit your mood. Many amps ship with basic - often the cheapest available - tubes. Its only natural that those with something better will try the replacements.
As for bass and treble controls - sir, can you honestly come here and tell me that you dont know the contempt with which audiophiles hold such fripperies ?
Please, for your own sake, I urge you to read the article below. Its written by a dreadful snob, but a snob who knows what he is talking about - I am told that he designed a modified Magnepan speaker which is widely regarded as the best of its kind. I have pasted his thoughts on tone controls for your edification - just as his fanaticism for tube amps and vinyl matters little to me, I have no problem with amps with tone controls, for I am a music lover and not an audiophile. History has taught me that I have to be able to live with my neighbours - I would suggest that you might like to do the same.
Tone Controls - In almost all cases there are none. I know, you're used to 5 million bells and whistles and lights, and perhaps an lcd screen. Well, it turns out that's all crap. Good gear does not have tone controls because it doesn't need tone controls. You get a volume control, an input selector and (sometimes not even) a balance control. Why? First of all, the gear is doing it's job of reproducing the music right, so it doesn't need to be corrected. Secondly, every time the signal gets run thru something like that it gets degraded. So again, like in so many things in life, less is more. Don't be thrown by what looks like a lack of features. The features are built in. If corrections need to be made they need to be because your room has a flaw. Therefore the proper answer is to treat the rooms issue and not "break" the sound at the gear to accomodate a problem. A good example of modern "mid-fi" gear is this Jolida 502B integrated tube amp. Attractive looks, 8 tubes, a power switch and 2 controls. Your gateway to sonic bliss.
