Pass First Watt J2 vs F3

i heard both in my system and they are both excellent. i choose the J2 for two reasons:

1. More dynamic range in my system, the extra power.
2. The F3 has very low imput impedence and was a poor match with my Hovland pre.

awesome amps

Jeff's 2nd point is very important, those J and J2s really are easy loads for tube preamps, which is a must for me if I'm using a SS amp.

Another vote for Atma-sphere amps (own M60s), my favorite amps ever with appropriate speakers. That being said, the Pass Aleph 2, 3, XA30.5, and Aleph Js are all wonderful SS amps, and I assume the others I have not owned.

I heard a Pass XA30.5 driving a pair of JBL Everest speakers a couple of years ago. It was stunning. Too bad the Everest is around $50-60K.

I have owned both, liked both, and still have the J2. The funny thing is that I don't find them all that similar. The J2 is much more energetic, more detailed, more like the AJ with a slightly cleaner sound. To my ear, the F3 is ridiculously good--if your speakers are sufficiently sensitive. The J2 obviously brings more speakers into play, but it still needs 8 ohms. I hope that helps.

Jumping in 4.5 years later. Have J6 and Zu Soul Superfly on the way. Excited to pair it up with the VAC Ren preamp. Expecting some magic to happen . . .
