Once I tried LP, I realized I like well implemented Cavalli sound. I also realized his circuit designs are created for good taste in sound if that makes sense. A good design I find is a sound that is seemingly detailed or has the technical resolvability without sounding clinical. I'm afraid a lot of solid-state designs suffer this.
Like any designs, it takes work and effort to realize a good taste. It doesn't get handed on a chip.
Also, I'm not sure what is a real tuby sound or you are referring to. Is a real tubey sound desireable? If you listened to Eddie Current tube amps, they don't have stereotypical 'tubey' qualities, but are very technically sounding amps with qualities that a solid-state can have.
So, the question would be what is this tubeyness desired, and is this ultimately desireable for the sound outcome?
I personally like precision in the sound, so a realy tubeyness is likely a no no. I do not want warm, thick slow goeyness in sound, but high resolve, fast, with non-clinical musicalness with tubes or SS.
As far as LP sound I notice, it's thicker and meatier in the mids than neutral, also has good technicalities to sound detailed. It's likely more of a complementary to leaner sounding headphones than already thick. Ultimately about preference in how meaty you like your sound.
