excellent Data Mining Mr. Apogee!

a lot of good discussions back in the early Aughts (2000's) - that can still illuminate the current day.

What are the sound differences between the F5 and Aleph J? Any thoughts from the group.

I am looking to build an amplifier and have narrowed my choices to either of this two due to pre-printed circuit boards being available, power, and damping factor.

they have most almost most opposite signatures in FW family :-). Nelson mentioned this earlier. F5 is very clean and holographical, with a great soundstage. AJ is more sweeter, a little bit of a sweet coloration. With an outstanding dynamics! I would go for AJ if you ask me, but it needs bigger heatsinks.

Aleph 3 is still the bestest

The game changer! Also the best looking!!! Hot Spiney Stuff

(TO-3 Fets = better sound than TO-247)

not so opposite as F5 vs. F1 , 2 , 3

regarding heatsinks - F5 and Aleph J are pretty much in same ballpark ..... meaning - juice is your choice , as long you're above Klunk! area

(not that J will give much above Klunk!)

The Amp Camp Amp has the characteristic that the 1W distortion raises slightly at high frequencies. 0.7% at 1KHz and below, 1% at 10KHz, 1.4% at 20KHz. I attribute this to the input capacitance of the IRFP240. I changed the IRFP240 to an IRF520 and that reduced the high frequency distortion. This softened the high end, graphs are posted in the ACA sticky thread. In listening tests I turned the tweeters up a couple of clicks, probably closer to flat with the !RF520 version. Overall the differences are small. Do other Pass amps do this?

Hi guys,

Where would something like the Adcom 5500 fit in sonicly? I know it's a different bird but available for reasonable pricing so ...thought I'd ask anyway.
