My confusion too. Was thinking of sending my 3Cs to Audeze to get Fazored, thinking that is the only difference. I expected a little clearer top end, maybe better imaging. I went to my local dealer and auditioned the first 3F, to hear if there was much difference. I then took those home to audition and A/B with my 3C in my system. Quite a large difference, especially in the bass. I suspected then that they had different drivers. Took back those 3F, and bought a new pair. Those still sound quite different than my 3C.
Maybe Audeze should have released them as a LCD-4, or there is a true LCD-4 lurking very soon. They would look very luxurious with ivory cups.
Today I have heard LCD 3 Fasor for the first time
Source : Marantz CD player
Amp : Bakoon I forgot the model
My first impression more or less like yours
Compare to LCD 3 Classic
LCD 3 F
High : more clarity and better detail more presence
Mid : very sweet and analog , the best mid from all LCD series I have tried
Very intimate .i love the mid very much
Bass : very deep and clean , bass also the deepest in LCD series
Separation : very good
Soundstage : is wide with very good depth
Overall:
sound quality analog and neutral , with very good in detail and clarity
The strong point are mid so sweet and analog and intimate , I can not forget until now
The second strong point are bass very deep and clean and can going lower without distortion
Compare to LCD X
LCD X
High : is brighter and slightly better clarity compare LCD 3 F
Mid : is a bit backward , LCD 3 F is forward and more intimate
Bass : LCD 3 F is very deep and low Bass and very clean , LCD X can not produce so kind of bass
I guess maybe different material in metal LCD X and wood in LCD 3 F
Separation : LCD X has slightly better music separation
Soundstage : LCD X has wider soundstage , but less depth , LCD 3 F has better layering too
Today I wish I can bought LCD 3 F , but no stock , at the end I bought LCD X first
And I am waiting for the the next batch and I want to try LCD 3 F again
IMO
