LP12 is like a traditional tube EL34/Kt88 tube. Some dismiss it as old school while others consider it musically charming and relevant.
I have heard LP12 sound very ordinary and very awesome.
Many modern TTs have very low (CD like?) noise floor and expansive soundstage, pin point imaging and big dynamics. Thats their achievement which is to be applauded. But do they represent music the way it was intended by the musicians? A lot of them just fall flat on this ground alone. An AMG Viela V12 sounds dead boring🥱. A Dohmann Helix takes pride in its all out effort for isolation, but play some Michael Jackson on it and see if the "king of the pop" feels like he is taking hou back in time to groove again. Just doesn't happen! All the imaging and soundstaging specificity is there to wow the listener as long as that's what the recording is all about. A Kronos TT sounds like a CD with better dynamics. Dry harmonics and discrete flow. I can go on and on. I have heard a lot of these TTs and it is extremely disappointing what today's one man designer voiced equipments sound like.
Before some consider me as a LP12 fanboy, my favourite reference TTs are Kondo Ginga, Hartvig, SME 30/12, EMT 927, Micro Seiki 5000 and 8000 etc
If I list out all the modern TTs which suck at keeping the integrity of the music, the list will be very long.
