Default Between F4 and F5

Did anyone compare those two amps directly, or can comment about the sound quality difference between the two?

F5 (almost ) doesn't need preamp ;

F4 ( being follower , without voltage gain ) demands serious preamp ( decent voltage swing ) ;

that means that you only can compare F5 vs. preamp+F4

F5 very fast and detailed,bit dry.
F4 more ''Musical'' can sound great with tube preamp.

Okay than, any comparison between F5 and F4+pre?

P.S.,
When dealing with power amp, a pre-amp is given (in my mind and in my experience).

Thank you very much.
Your phrase {more "musical"} tells me all I wanted to hear.
Also, I'm using a tube pre-amp anyhow, and it isn't going to be changed.

P.S.,
I intend to use either one (F4 or F5) in a balanced-bridged mono configuration.
Right no my vote is for F4.

The only thing that stops me from building F5 is that every one is building one and everyone is raving about it and telling how good it is. Same with wines at my local wine store, if everyone is buying one I know it will not be good for me and will not satisfy me. Really I could have built F5 three times already by now if not the thing that everybody is building it and saying it is great amp. Having built Aleph 4, Aleph 3 and a couple of zens amps I bet with proper speakers F3 or F4 beats F5 hands down.

My mate built the F5, I've borrowed it a few times, but for me F4 & pumpkin is very hard to beat very musical.
