I'm tempted to say that if you have good equipment which is capable of covering a wide tonal spectrum, then finding Nirvana is more a matter of getting The Sound from your Mind to your Fingers. This would entail having the fingers follow the mind, so if, for example, you always keep your right hand in the same spot- well, let that sucker wander! Left-hand variations might also ensue. (Swap if left-handed!)
Recording introduces a whole different sack of woe to the picture; my attempts at home recording convinced me that there's very good reasons for engineers and producers to be well paid, and for dedicated recording studios to exist.
Still, perhaps the key is having The Sound You Want firmly in mind (allowing for your technical abilities at present), and to just keep your fingers looking for it (including any technical advances)- if you've got The Tone in the head-bone, it's got to leak out the finger-bones eventually! Meanwhile, you may discover some other tones you like too, and the sound of The Tone may grow richer as a result.
It's not always a matter of buying more stuff. Jimmy Page got some awesome guitar tones by putting a little Supro amp in a hallway or whatever- and by, you know, being Jimmy Page! Which do you suppose was most important?
YOUR tone is in you- keep playing till you get out of its way!
[Apologies if MY "tone" here is insufferably pseudo-Cosmic Debris/motivational-speaker-ish, but you get the idea.]
