May still be some floating around. I would assume better linearity, not that it is important to Aleph sound.

Happy to hear that someone shares my experience that the 9610 inputstage is still worth being tried.

My last experience with it was a J2 clone with them in the inputstage instead of double J109.
Also a fine sound!

I tried an R550 in an Aleph P, the sound was less dark but it was not a big jump forward in my ears.

Just for the record I want to mention it here:

From my own experience (at least if you do not have insanely sensitive speakers): Pa's SE amps do sound better with an active preamp. I plugged a Forte model 2 preamp(not the most analog sounding pre) to my Aleph (now its Aleph 30). It revealed some more details which SE amps hide compare to my F5, added some depth, a little bit punch and dynamics on intense, dense music. So, I will be making an active pre for SE amps from now on. (I do not need it on me F5Tv2 :-)

Me? It was not me ;-) I am still waiting for F6 kit and Primrose GB's. Maybe this is the time to build some preamps.
